Docker安装配置JupyterNotebook详解-Toy模板网

这篇具有很好参考价值的文章主要介绍了Docker安装配置JupyterNotebook详解。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

因为Docker Hub无法打开，Jupyter Notebook等官方镜像也无法下载，所以另辟蹊径下载了热门的Python3基础镜像，从头开始安装纯净版本的Jupyter Notebook环境，本文记录了完整的Jupyter Notebook安装过程，方便自己查阅，也供其他人员参考，请确保当前已有Docker运行环境

直接拉取最新Python镜像，映射宿主机与容器内部目录，因为目前只用到Notebook的Web服务，所以只映射了一个端口开放使用

docker run -itd -p 2222:2222 -v /home/jupyter:/home/jupyter --name jupyter python

进入镜像容器内部

docker exec -it `容器编号` /bin/bash

设置pip下载镜像源为清华

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

下载jupyter，默认会下载最新版本7.X的Notebook，但是目前最新版本安装nbextensions插件会报错，所以这里下载6.X的Notebook最后版本

pip install jupyter

pip install jupyter notebook==6.5.5

生成Jupyter默认配置文件，并自定义配置选项

jupyter notebook --generate-config

部分系统或者其他版本下可能会提示 ModuleNotFoundError: No module named 'jupyter_server.contents',可以使用jupyter notebook --generate-config解决，并且后续启动也是使用jupyter notebook启动

生成配置文件后，控制台会打印生成的文件地址，通常是这个 `/root/.jupyter/jupyter_notebook_config.py`，如果生成的文件已经存在，会提示你是否需要覆盖，根据自己需要选择即可

因为此镜像没有`Vim`编辑器，我们可以按照如下步骤使用`cat`快速编辑保存配置

使用cat jupyter_notebook_config.py命令查看配置文件，并选中复制到电脑文本中
找到如下配置项，不同版本略有不同，但后缀相同，最后会附上当前完整配置以供参考
- c.NotebookApp.allow_remote_access = True # 允许远程访问
- c.NotebookApp.ip='0.0.0.0' # 自动获取服务器ip
- c.NotebookApp.allow_root =True # 打开root权限启动
- c.NotebookApp.open_browser = False # 服务端禁止自动打开浏览器
- c.NotebookApp.port = 2222 # 创建docker时候配置的端口号
上面设置项改完后，可以复制编辑好的全部配置文件，使用命令cat > jupyter_notebook_config.py ，覆盖当前所有配置，最后 Ctrl+D保存文本，也可以使用命令cat >> jupyter_notebook_config.py 追加自己更改的设置项

配置文件成功后，可以在当前目录使用命令 jupyter notebook启动服务，控制台没什么报错的话会打印Jupyter Notebook访问地址链接，复制好链接中的token后面的值，我们便可以在打开的页面中输入token值，用来设置初始访问密码

当然我们可以事先生成密码，然后设置到配置文件中，但是上面的方法更为简单，以下方法仅供参考

ipython
from notebook.auth import passwd
passwd()
Enter password: XXXX
Verify password: XXXX
Out[2]: '生成的密钥'

复制生成的密钥，填入配置文件的 c.NotebookApp.password 项中注意前面有 u

示例 c.NotebookApp.password=u'生成的密钥'

现在有更好的办法设置密码，并且解决在登录总是失败报错的问题

输入jupyter notebook password，根据提示，确认新的密码，密码将写入到jupyter_notebook_config.json文件中。该json配置文件的优先级高于此前设置的jupyter_notebook_config.py文件，写入完成后需要重启服务生效

后台运行Jupyter Notebook

上面使用命令jupyter notebook启动服务后，控制台不方便执行其他命令，可以先使用Ctrl+C中断服务，在当前目录下使用nohup jupyter notebook &以启动后台服务，默认当前目录为工作目录，新建的文件会保存在此处，也可以指定工作目录，如jupyter notebook --notebook-dir='工作目录地址',注意，如果当前端口存在冲突时，Jupyter服务的端口会自动顺延至下一个可用的端口，会导致服务无法访问，可以使用命令 ps aux |grep note查看当前是否已存在运行服务，然后使用kill -9 服务的PID杀掉对应进程

下载插件管理器nbextensions，并安装

pip install jupyter_contrib_nbextensions && jupyter contrib nbextension install --user

当前我开启的插件，根据自己需求来

Export Embedded HTML
RISE
Hinterland
Nbextensions dashboard tab
Table of Contents (2)
Variable Inspector
Code prettify
Hide input all
Nbextensions edit menu item
zenmode

使用主题(优雅的主题更舒心)

pip install jupyterthemes

可以使用 jt -ls 查看当前所有主题名称，jt -t 主题名称可以切换到对应主题，切换主题，通常无需重启Jupyter Notebook，刷新Notebook页面即可看到变化，最后可以使用jt -r还原为默认主题

附我当前使用的主题配置 jt -t gruvboxd -fs 12 -cellw 80% -ofs 11 -dfs 11 -T -N

说明 -f(字体) -fs(字体大小) -cellw(占屏比或宽度) -ofs(输出段的字号) -T(显示工具栏) -N(显示自己主机名)文章来源地址https://www.toymoban.com/news/detail-704887.html

# Configuration file for jupyter-notebook.

c = get_config()  #noqa

#------------------------------------------------------------------------------
# Application(SingletonConfigurable) configuration
#------------------------------------------------------------------------------
## This is an application.

## The date format used by logging formatters for %(asctime)s
#  Default: '%Y-%m-%d %H:%M:%S'
# c.Application.log_datefmt = '%Y-%m-%d %H:%M:%S'

## The Logging format template
#  Default: '[%(name)s]%(highlevel)s %(message)s'
# c.Application.log_format = '[%(name)s]%(highlevel)s %(message)s'

## Set the log level by value or name.
#  Choices: any of [0, 10, 20, 30, 40, 50, 'DEBUG', 'INFO', 'WARN', 'ERROR', 'CRITICAL']
#  Default: 30
# c.Application.log_level = 30

## Configure additional log handlers.
#
#  The default stderr logs handler is configured by the log_level, log_datefmt
#  and log_format settings.
#
#  This configuration can be used to configure additional handlers (e.g. to
#  output the log to a file) or for finer control over the default handlers.
#
#  If provided this should be a logging configuration dictionary, for more
#  information see:
#  https://docs.python.org/3/library/logging.config.html#logging-config-
#  dictschema
#
#  This dictionary is merged with the base logging configuration which defines
#  the following:
#
#  * A logging formatter intended for interactive use called
#    ``console``.
#  * A logging handler that writes to stderr called
#    ``console`` which uses the formatter ``console``.
#  * A logger with the name of this application set to ``DEBUG``
#    level.
#
#  This example adds a new handler that writes to a file:
#
#  .. code-block:: python
#
#     c.Application.logging_config = {
#         'handlers': {
#             'file': {
#                 'class': 'logging.FileHandler',
#                 'level': 'DEBUG',
#                 'filename': '<path/to/file>',
#             }
#         },
#         'loggers': {
#             '<application-name>': {
#                 'level': 'DEBUG',
#                 # NOTE: if you don't list the default "console"
#                 # handler here then it will be disabled
#                 'handlers': ['console', 'file'],
#             },
#         }
#     }
#  Default: {}
# c.Application.logging_config = {}

## Instead of starting the Application, dump configuration to stdout
#  Default: False
# c.Application.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  Default: False
# c.Application.show_config_json = False

#------------------------------------------------------------------------------
# JupyterApp(Application) configuration
#------------------------------------------------------------------------------
## Base class for Jupyter applications

## Answer yes to any prompts.
#  Default: False
# c.JupyterApp.answer_yes = False

## Full path of a config file.
#  Default: ''
# c.JupyterApp.config_file = ''

## Specify a config file to load.
#  Default: ''
# c.JupyterApp.config_file_name = ''

## Generate default config file.
#  Default: False
# c.JupyterApp.generate_config = False

## The date format used by logging formatters for %(asctime)s
#  See also: Application.log_datefmt
# c.JupyterApp.log_datefmt = '%Y-%m-%d %H:%M:%S'

## The Logging format template
#  See also: Application.log_format

## Instead of starting the Application, dump configuration to stdout
#  See also: Application.show_config
# c.JupyterApp.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  See also: Application.show_config_json
# c.JupyterApp.show_config_json = False

#------------------------------------------------------------------------------
# NotebookApp(JupyterApp) configuration
#------------------------------------------------------------------------------
## Set the Access-Control-Allow-Credentials: true header
#  Default: False
# c.NotebookApp.allow_credentials = False

## Set the Access-Control-Allow-Origin header
#
#          Use '*' to allow any origin to access your server.
#
#          Takes precedence over allow_origin_pat.
#  Default: ''
# c.NotebookApp.allow_origin = ''

## Use a regular expression for the Access-Control-Allow-Origin header
#
#          Requests from an origin matching the expression will get replies with:
#
#              Access-Control-Allow-Origin: origin
#
#          where `origin` is the origin of the request.
#
#          Ignored if allow_origin is set.
#  Default: ''
# c.NotebookApp.allow_origin_pat = ''

## Allow password to be changed at login for the notebook server.
#
#                      While logging in with a token, the notebook server UI will give the opportunity to
#                      the user to enter a new password at the same time that will replace
#                      the token login mechanism.
#
#                      This can be set to false to prevent changing password from
#  the UI/API.
#  Default: True
# c.NotebookApp.allow_password_change = True

## Allow requests where the Host header doesn't point to a local server
#
#         By default, requests get a 403 forbidden response if the 'Host' header
#         shows that the browser thinks it's on a non-local domain.
#         Setting this option to True disables this check.
#
#         This protects against 'DNS rebinding' attacks, where a remote web server
#         serves you a page and then changes its DNS to send later requests to a
#         local IP, bypassing same-origin checks.
#
#         Local IP addresses (such as 127.0.0.1 and ::1) are allowed as local,
#         along with hostnames configured in local_hostnames.
#  Default: False
c.NotebookApp.allow_remote_access = True

## Whether to allow the user to run the notebook as root.
#  Default: False
c.NotebookApp.allow_root = True

## Answer yes to any prompts.
#  See also: JupyterApp.answer_yes
# c.NotebookApp.answer_yes = False

## "

#  Default: False
# c.NotebookApp.autoreload = False

## DEPRECATED use base_url
#  Default: '/'
# c.NotebookApp.base_project_url = '/'

## The base URL for the notebook server.
#
#                                 Leading and trailing slashes can be omitted,
#                                 and will automatically be added.
#  Default: '/'
# c.NotebookApp.base_url = '/'

## Specify what command to use to invoke a web
#                        browser when opening the notebook. If not specified, the
#                        default browser will be determined by the `webbrowser`
#                        standard library module, which allows setting of the
#                        BROWSER environment variable to override it.
#  Default: ''
# c.NotebookApp.browser = ''

## The full path to an SSL/TLS certificate file.
#  Default: ''
# c.NotebookApp.certfile = ''

## The full path to a certificate authority certificate for SSL/TLS client
#  authentication.
#  Default: ''
# c.NotebookApp.client_ca = ''

# c.NotebookApp.config_manager_class = 'notebook.services.config.manager.ConfigManager'

## The notebook manager class to use.
#  Default: 'notebook.services.contents.largefilemanager.LargeFileManager'
# c.NotebookApp.contents_manager_class = 'notebook.services.contents.largefilemanager.LargeFileManager'

## Extra keyword arguments to pass to `set_secure_cookie`. See tornado's
#  set_secure_cookie docs for details.
#  Default: {}
# c.NotebookApp.cookie_options = {}

## The random bytes used to secure cookies.
#          By default this is a new random number every time you start the Notebook.
#          Set it to a value in a config file to enable logins to persist across server sessions.
#
#          Note: Cookie secrets should be kept private, do not share config files with
#          cookie_secret stored in plaintext (you can read the value from a file).
#  Default: b''
# c.NotebookApp.cookie_secret = b''

## The file where the cookie secret is stored.
#  Default: ''
# c.NotebookApp.cookie_secret_file = ''

## Override URL shown to users.
#
#          Replace actual URL, including protocol, address, port and base URL,
#          with the given value when displaying URL to the users. Do not change
#          the actual connection URL. If authentication token is enabled, the
#          token is added to the custom URL automatically.
#
#          This option is intended to be used when the URL to display to the user
#          cannot be determined reliably by the Jupyter notebook server (proxified
#          or containerized setups for example).
#  Default: ''
# c.NotebookApp.custom_display_url = ''

## The default URL to redirect to from `/`
#  Default: '/tree'
# c.NotebookApp.default_url = '/tree'

## Disable cross-site-request-forgery protection
#
#          Jupyter notebook 4.3.1 introduces protection from cross-site request forgeries,
#          requiring API requests to either:
#
#          - originate from pages served by this server (validated with XSRF cookie and token), or
#          - authenticate with a token
#
#          Some anonymous compute resources still desire the ability to run code,
#          completely without authentication.
#          These services can disable all authentication and security checks,
#          with the full knowledge of what that implies.
#  Default: False
# c.NotebookApp.disable_check_xsrf = False

## Whether to enable MathJax for typesetting math/TeX
#
#          MathJax is the javascript library Jupyter uses to render math/LaTeX. It is
#          very large, so you may want to disable it if you have a slow internet
#          connection, or for offline use of the notebook.
#
#          When disabled, equations etc. will appear as their untransformed TeX
#  source.
#  Default: True
# c.NotebookApp.enable_mathjax = True

#  Default: []
# c.NotebookApp.extra_static_paths = []

## Extra paths to search for serving jinja templates.
#
#          Can be used to override templates from notebook.templates.

# c.NotebookApp.extra_template_paths = []

#  Default: ''
# c.NotebookApp.file_to_run = ''

## Generate default config file.
#  See also: JupyterApp.generate_config
# c.NotebookApp.generate_config = False

## Extra keyword arguments to pass to `get_secure_cookie`. See tornado's
#  get_secure_cookie docs for details.

#  recompilation
#  Default: False
# c.NotebookApp.ignore_minified_js = False

## (bytes/sec)
#          Maximum rate at which stream output can be sent on iopub before they are
#          limited.

# c.NotebookApp.iopub_data_rate_limit = 1000000

## (msgs/sec)
#          Maximum rate at which messages can be sent on iopub before they are

## Extra variables to supply to jinja templates when rendering.
#  Default: {}
# c.NotebookApp.jinja_template_vars = {}

## The kernel manager class to use.
#  Default: 'notebook.services.kernels.kernelmanager.MappingKernelManager'
# c.NotebookApp.kernel_manager_class = 'notebook.services.kernels.kernelmanager.MappingKernelManager'

## The kernel spec manager class to use. Should be a subclass of
#  `jupyter_client.kernelspec.KernelSpecManager`.
#
#  The Api of KernelSpecManager is provisional and might change without warning
#  between this version of Jupyter and the next stable one.
#  Default: 'jupyter_client.kernelspec.KernelSpecManager'
# c.NotebookApp.kernel_spec_manager_class = 'jupyter_client.kernelspec.KernelSpecManager'

## The full path to a private key file for usage with SSL/TLS.
#  Default: ''
# c.NotebookApp.keyfile = ''

## Hostnames to allow as local when allow_remote_access is False.
#
#         Local IP addresses (such as 127.0.0.1 and ::1) are automatically accepted
#         as local as well.
#  Default: ['localhost']
# c.NotebookApp.local_hostnames = ['localhost']

#  See also: Application.log_datefmt
# c.NotebookApp.log_datefmt = '%Y-%m-%d %H:%M:%S'

## The Logging format template
#  See also: Application.log_format
# c.NotebookApp.log_format = '[%(name)s]%(highlevel)s %(message)s'

#  Default: ''
# c.NotebookApp.mathjax_url = ''

## Sets the maximum allowed size of the client request body, specified in the

#  open files. This is not applicable when running on Windows.
#  Default: 0
# c.NotebookApp.min_open_files_limit = 0

## Dict of Python modules to load as notebook server extensions. Entry values can
#  be used to enable and disable the loading of the extensions. The extensions
#  will be loaded in alphabetical order.
#  Default: {}
# c.NotebookApp.nbserver_extensions = {}

## The directory to use for notebooks and kernels.
#  Default: ''
# c.NotebookApp.notebook_dir = ''

## Whether to open in a browser after starting.
#                          The specific browser used is platform dependent and
#                          determined by the python standard library `webbrowser`
#                          module, unless it is overridden using the --browser
#                          (NotebookApp.browser) configuration option.
#  Default: True
c.NotebookApp.open_browser = False

## Hashed password to use for web authentication.
#
#                        To generate, type in a python/IPython shell:
#
#                          from notebook.auth import passwd; passwd()

#                        The string should be of the form type:salt:hashed-
#  password.
#  Default: ''
# c.NotebookApp.password = ''

## Forces users to use a password for the Notebook server.
#                        This is useful in a multi user environment, for instance when
#                        everybody in the LAN can access each other's machine through ssh.
#
#                        In such a case, serving the notebook server on localhost is not secure
#                        since any user can connect to the notebook server via ssh.
#  Default: False
# c.NotebookApp.password_required = False

## The port the notebook server will listen on (env: JUPYTER_PORT).
#  Default: 8888
c.NotebookApp.port = 2222

## The number of additional ports to try if the specified port is not available
#  (env: JUPYTER_PORT_RETRIES).
#  Default: 50
# c.NotebookApp.port_retries = 50

## DISABLED: use %pylab or %matplotlib in the notebook to enable matplotlib.
#  Default: 'disabled'
# c.NotebookApp.pylab = 'disabled'

## If True, display a button in the dashboard to quit
#          (shutdown the notebook server).
#  Default: True
# c.NotebookApp.quit_button = True

## (sec) Time window used to
#          check the message and data rate limits.
#  Default: 3
# c.NotebookApp.rate_limit_window = 3

## Reraise exceptions encountered loading server extensions?
#  Default: False
# c.NotebookApp.reraise_server_extension_failures = False

## DEPRECATED use the nbserver_extensions dict instead
#  Default: []
# c.NotebookApp.server_extensions = []

## The session manager class to use.
#  Default: 'notebook.services.sessions.sessionmanager.SessionManager'
# c.NotebookApp.session_manager_class = 'notebook.services.sessions.sessionmanager.SessionManager'

## Whether the banner is displayed on the page.
#
#                          By default, the banner is displayed.
#  Default: True
# c.NotebookApp.show_banner = True

## Instead of starting the Application, dump configuration to stdout
#  See also: Application.show_config
# c.NotebookApp.show_config = False

## Instead of starting the Application, dump configuration to stdout (as JSON)
#  See also: Application.show_config_json
# c.NotebookApp.show_config_json = False

## Shut down the server after N seconds with no kernels or terminals running and
#  no activity. This can be used together with culling idle kernels
#  (MappingKernelManager.cull_idle_timeout) to shutdown the notebook server when
#  it's not in use. This is not precisely timed: it may shut down up to a minute
#  later. 0 (the default) disables this automatic shutdown.
#  Default: 0
# c.NotebookApp.shutdown_no_activity_timeout = 0

## The UNIX socket the notebook server will listen on.
#  Default: ''
# c.NotebookApp.sock = ''

## The permissions mode for UNIX socket creation (default: 0600).
#  Default: '0600'
# c.NotebookApp.sock_mode = '0600'

## Supply SSL options for the tornado HTTPServer.
#              See the tornado docs for details.
#  Default: {}
# c.NotebookApp.ssl_options = {}

## Supply overrides for terminado. Currently only supports "shell_command". On
#  Unix, if "shell_command" is not provided, a non-login shell is launched by
#  default when the notebook server is connected to a terminal, a login shell
#  otherwise.
#  Default: {}
# c.NotebookApp.terminado_settings = {}

## Set to False to disable terminals.
#
#           This does *not* make the notebook server more secure by itself.
#           Anything the user can in a terminal, they can also do in a notebook.
#
#           Terminals may also be automatically disabled if the terminado package
#           is not available.
#  Default: True
# c.NotebookApp.terminals_enabled = True

## Token used for authenticating first-time connections to the server.
#
#          The token can be read from the file referenced by JUPYTER_TOKEN_FILE or set directly
#          with the JUPYTER_TOKEN environment variable.
#
#          When no password is enabled,
#          the default is to generate a new, random token.
#
#          Setting to an empty string disables authentication altogether, which
#  is NOT RECOMMENDED.
#  Default: '<generated>'
# c.NotebookApp.token = '<generated>'

## Supply overrides for the tornado.web.Application that the Jupyter notebook
#  uses.
#  Default: {}
# c.NotebookApp.tornado_settings = {}

## Whether to trust or not X-Scheme/X-Forwarded-Proto and X-Real-Ip/X-Forwarded-
#  For headers sent by the upstream reverse proxy. Necessary if the proxy handles
#  SSL
#  Default: False
# c.NotebookApp.trust_xheaders = False

## Disable launching browser by redirect file
#
#          For versions of notebook > 5.7.2, a security feature measure was added that
#          prevented the authentication token used to launch the browser from being visible.
#          This feature makes it difficult for other users on a multi-user system from
#          running code in your Jupyter session as you.
#
#          However, some environments (like Windows Subsystem for Linux (WSL) and Chromebooks),
#          launching a browser using a redirect file can lead the browser failing to load.
#          This is because of the difference in file structures/paths between the runtime and
#          the browser.
#
#          Disabling this setting to False will disable this behavior, allowing the browser
#          to launch by using a URL and visible token (as before).
#  Default: True
# c.NotebookApp.use_redirect_file = True

## DEPRECATED, use tornado_settings
#  Default: {}
# c.NotebookApp.webapp_settings = {}

## Specify Where to open the notebook on startup. This is the
#          `new` argument passed to the standard library method `webbrowser.open`.
#          The behaviour is not guaranteed, but depends on browser support. Valid
#          values are:
#
#           - 2 opens a new tab,
#           - 1 opens a new window,
#           - 0 opens in an existing window.
#
#          See the `webbrowser.open` documentation for details.
#  Default: 2
# c.NotebookApp.webbrowser_open_new = 2

## Set the tornado compression options for websocket connections.
#
#  This value will be returned from
#  :meth:`WebSocketHandler.get_compression_options`. None (default) will disable
#  compression. A dict (even an empty one) will enable compression.
#
#  See the tornado docs for WebSocketHandler.get_compression_options for details.
#  Default: None
# c.NotebookApp.websocket_compression_options = None

## The base URL for websockets,
#          if it differs from the HTTP server (hint: it almost certainly doesn't).
#
#          Should be in the form of an HTTP origin: ws[s]://hostname[:port]

# Session(Configurable) configuration
#------------------------------------------------------------------------------
## Object for handling serialization and sending of messages.
#
#      The Session object handles building messages and sending them
#      with ZMQ sockets or ZMQStream objects.  Objects can communicate with each
#      other over the network via Session objects, and only need to work with the
#      dict-based IPython message spec. The Session will handle
#      serialization/deserialization, security, and metadata.
#
#      Sessions support configurable serialization via packer/unpacker traits,
#      and signing with HMAC digests via the key/keyfile traits.
#
#      Parameters
#      ----------
#
#      debug : bool
#          whether to trigger extra debugging statements
#      packer/unpacker : str : 'json', 'pickle' or import_string
#          importstrings for methods to serialize message parts.  If just
#          'json' or 'pickle', predefined JSON and pickle packers will be used.
#          Otherwise, the entire importstring must be used.
#
#          The functions must accept at least valid JSON input, and output
#  *bytes*.
#
#          For example, to use msgpack:
#          packer = 'msgpack.packb', unpacker='msgpack.unpackb'
#      pack/unpack : callables
#          You can also set the pack/unpack callables for serialization directly.
#      session : bytes
#          the ID of this Session object.  The default is to generate a new UUID.
#      username : unicode
#          username added to message headers.  The default is to ask the OS.
#      key : bytes
#          The key used to initialize an HMAC signature.  If unset, messages
#          will not be signed or checked.
#      keyfile : filepath
#          The file containing a key.  If this is set, `key` will be initialized
#          to the contents of the file.

## Threshold (in bytes) beyond which an object's buffer should be extracted to
#  avoid pickling.
#  Default: 1024
# c.Session.buffer_threshold = 1024

## Whether to check PID to protect against calls after fork.
#
#          This check can be disabled if fork-safety is handled elsewhere.

#  Default: 65536
# c.Session.copy_threshold = 65536

# c.Session.digest_history_size = 65536

## The maximum number of items for a container to be introspected for custom serialization.
#          Containers larger than this are pickled outright.
#  Default: 64
# c.Session.item_threshold = 64

## execution key, for signing messages.
#  Default: b''
# c.Session.key = b''

## path to file containing execution key.
#  Default: ''
# c.Session.keyfile = ''

## Metadata dictionary, which serves as the default top-level metadata dict for
#  each message.
#  Default: {}
# c.Session.metadata = {}

## The name of the packer for serializing messages.
#              Should be one of 'json', 'pickle', or an import name
#              for a custom callable serializer.
#  Default: 'json'
# c.Session.packer = 'json'

## The UUID identifying this session.
#  Default: ''
# c.Session.session = ''

## The digest scheme used to construct the message signatures.
#          Must have the form 'hmac-HASH'.

## The name of the default kernel to start
#  See also: MultiKernelManager.default_kernel_name
# c.MappingKernelManager.default_kernel_name = 'python3'

## Timeout for giving up on a kernel (in seconds).
#          On starting and restarting kernels, we check whether the
#          kernel is running and responsive by sending kernel_info_requests.
#          This sets the timeout in seconds for how long the kernel can take
#          before being presumed dead.
#          This affects the MappingKernelManager (which handles kernel restarts)
#          and the ZMQChannelsHandler (which handles the startup).
#  Default: 60
# c.MappingKernelManager.kernel_info_timeout = 60

## The kernel manager class.  This is configurable to allow

#
#      - unicode, not url-escaped

## handler class to use when serving raw file requests.
#
#          Default is a fallback that talks to the ContentsManager API,

#
#          Local files-based ContentsManagers can use a StaticFileHandler subclass,
#          which will be much more efficient.
#
#          Access to these files should be Authenticated.
#  Default: 'notebook.files.handlers.FilesHandler'
# c.ContentsManager.files_handler_class = 'notebook.files.handlers.FilesHandler'

## Extra parameters to pass to files_handler_class.
