1.安装opencv: python -m pip install opencv-python

调用时为import cv2

2.要from PIL import Image

安装：conda install pillow

3.标准库：https://www.jb51.net/article/57834.htm

出现错误：
ERROR: Could not install packages due to an OSError: [WinError 5] 拒绝访问。: ‘d:\sf\anaconda3\envs\pytorch\lib\site-packages\~5py\defs.cp36-win_amd64.pyd’
Consider using the --user option or check the permissions.

则在package名称前面加上–user,增加管理员权限
如pip install tensorflow→pip install --user tensorflow

4.一些库对应python版本的安装版本：pypi

5.出现错误：安装h5pyViewer==0.0.1.6时

ERROR: Command errored out with exit status 1:

解决：python2版本的print是没有括号的，例如print x即可,且整数型数字前不能加0，例如x=0256不可以，要把0删掉。
而python3是python(x)

6.安装pycocotools==2.0时

ERROR: Command errored out with exit status 1:

解决：原本以为Cython_Build也需要pip install，但其并不是一个库，看样子应该是Cython内的一个子类别。使用pip show看一下自己的Cython有没有pip,pip成功了即可。——在这里我遇到了我pip install Cython显示succesfully,但是pip show Cython却说没有安装这个库，我重复了几次pip install就成功pip show了。
