1.安装tensorflow-gpu

Building wheels for collected packages: tensorflow-gpu

  Building wheel for tensorflow-gpu (setup.py): finished with status 'error'
  Running setup.py clean for tensorflow-gpu
  error: subprocess-exited-with-error

  × python setup.py bdist_wheel did not run successfully.

        File "/tmp/pip-install-i6frcfa8/tensorflow-gpu_2cea358528754cc596c541f9c2ce45ca/setup.py", line 37, in <module>
          raise Exception(TF_REMOVAL_WARNING)
      Exception:

      =========================================================
      The "tensorflow-gpu" package has been removed!

      Please install "tensorflow" instead.

      Other than the name, the two packages have been identical
      since TensorFlow 2.1, or roughly since Sep 2019. For more
      information, see: pypi.org/project/tensorflow-gpu
      =========================================================


      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for tensorflow-gpu
Failed to build tensorflow-gpu

Other than the name, the two packages have been identical since TensorFlow 2.1 也就是说安装2.1版本的已经自带GPU支持。

2.Docker使用GPU

不同型号的GPU及驱动版本有所区别，环境驱动及CUDA版本如下：

[root@localhost ~]# nvidia-smi
# 查询结果
+-----------------------------------------------------------------------------+
| NVIDIA-SMI 460.27.04    Driver Version: 460.27.04    CUDA Version: 11.2     |
|-------------------------------+----------------------+----------------------+

2.1 Could not find cuda drivers

# 报错
I tensorflow/tsl/cuda/cudart_stub.cc:28] Could not find cuda drivers on your machine, GPU will not be used.

在Docker容器中的程序无法识别CUDA环境变量，可以尝试以下步骤来解决这个问题：

检查CUDA版本：首先，需要确认宿主机上已经正确安装了CUDA。在宿主机上运行nvcc --version命令来检查CUDA版本。
使用NVIDIA Docker镜像：NVIDIA提供了一些预先配置好的Docker镜像，这些镜像已经包含了CUDA和其他必要的库。可以使用这些镜像作为Dockerfile的基础镜像。
设置环境变量：在Dockerfile中，可以使用ENV指令来设置环境变量。例如，如果CUDA安装在/usr/local/cuda目录下，可以添加以下行到Dockerfile中：ENV PATH /usr/local/cuda/bin:$PATH。
使用nvidia-docker：nvidia-docker是一个用于运行GPU加速的Docker容器的工具。

检测CUDA版本是必要的，由于使用的是导出的镜像文件，2和3的方法无法使用，最终使用-e进行环境变量设置：

# 添加cuda的环境变量
-e PATH=/usr/local/cuda-11.2/bin:$PATH -e LD_LIBRARY_PATH=/usr/local/cuda-11.2/lib64:$LD_LIBRARY_PATH

# 启动命令
nvidia-docker run --name deepface --privileged=true --restart=always --net="host" -e PATH=/usr/local/cuda-11.2/bin:$PATH -e LD_LIBRARY_PATH=/usr/local/cuda-11.2/lib64:$LD_LIBRARY_PATH -v /root/.deepface/weights/:/root/.deepface/weights/ -v /usr/local/cuda-11.2/:/usr/local/cuda-11.2/ -d deepface_image

2.2 was unable to find libcuda.so DSO

I tensorflow/compiler/xla/stream_executor/cuda/cuda_diagnostics.cc:168] retrieving CUDA diagnostic information for host: localhost.localdomain
I tensorflow/compiler/xla/stream_executor/cuda/cuda_diagnostics.cc:175] hostname: localhost.localdomain
I tensorflow/compiler/xla/stream_executor/cuda/cuda_diagnostics.cc:199] libcuda reported version is: NOT_FOUND: was unable to find libcuda.so DSO loaded into this program
I tensorflow/compiler/xla/stream_executor/cuda/cuda_diagnostics.cc:203] kernel reported version is: 460.27.4

在Linux环境下，Docker可以支持将宿主机上的目录挂载到容器里。这意味着，如果宿主机上的目录包含软链接，那么这些软链接也会被挂载到容器中。然而，需要注意的是，这些软链接指向的路径必须在Docker容器中是可访问的。也就是说，如果软链接指向的路径没有被挂载到Docker容器中，那么在容器中访问这个软链接可能会失败。
原文链接：https://blog.csdn.net/u013546508/article/details/88637434，当前环境下问题解决步骤：

# 1.查找 libcuda.so 文件位置
find / -name libcuda.so*
# 查找结果
/usr/lib/libcuda.so
/usr/lib/libcuda.so.1
/usr/lib/libcuda.so.460.27.04
/usr/lib64/libcuda.so
/usr/lib64/libcuda.so.1
/usr/lib64/libcuda.so.460.27.04

# 2.查看LD_LIBRARY_PATH
echo $LD_LIBRARY_PATH
# 查询结果
/usr/local/cuda/lib64

# 3.将64位的libcuda.so.460.27.04复制到LD_LIBRARY_PATH路径下【libcuda.so和libcuda.so.1都是软连接】
cp /usr/lib64/libcuda.so.460.27.04 /usr/local/cuda-11.2/lib64/

# 4.创建软连接
ln -s libcuda.so.460.27.04 libcuda.so.1
ln -s libcuda.so.1 libcuda.so

2.3 Could not find TensorRT&&Cannot dlopen some GPU libraries

Follow the guide at https://www.tensorflow.org/install/gpu for how to download and setup the required libraries for your platform.

这个问题实际上是Docker镜像文件未安装TensorRT导致的，可以在Dockerfile里添加安装命令后重新构建镜像：

RUN pip install tensorrt -i https://pypi.tuna.tsinghua.edu.cn/simple

以下操作不推荐，进入容器进行安装：

# 1.查询容器ID
docker ps

# 2.在running状态进入容器
docker exec -it ContainerID /bin/bash

# 3.安装软件
pip install tensorrt -i https://pypi.tuna.tsinghua.edu.cn/simple

# 4.提交新的镜像【可以将新的镜像导出使用】
docker commit ContainerID imageName:version

安装后的现象：

# 先导入tensorrt后使用tensorflow看我用

尝试解决，在容器启动要执行的py文件内加入以下代码，我将以下代码加入到app.py文件内：

import tensorrt as tr
import tensorflow as tf

if __name__ == "__main__":
    available = tf.config.list_physical_devices('GPU')
    print(f"available：{available}")

加入代码后的文件为：

# 3rd parth dependencies
import tensorrt as tr
import tensorflow as tf
from flask import Flask
from routes import blueprint

def create_app():
    available = tf.config.list_physical_devices('GPU')
    print(f"available：{available}")
    app = Flask(__name__)
    app.register_blueprint(blueprint)
    return app

启动容器：

nvidia-docker run --name deepface --privileged=true --restart=always --net="host" -e PATH=/usr/local/cuda-11.2/bin:$PATH -e LD_LIBRARY_PATH=/usr/local/cuda-11.2/lib64:$LD_LIBRARY_PATH -v /root/.deepface/weights/:/root/.deepface/weights/ -v /usr/local/cuda-11.2/:/usr/local/cuda-11.2/ -v /opt/xinan-facesearch-service-public/deepface/api/app.py:/app/app.py -d deepface_image

未安装cuDNN导致的问题，安装即可。

2.5 CuDNN library needs to have matching major version and equal or higher minor version

安装版本跟编译项目的版本不匹配，调整版本后成功使用GPU。文章来源地址https://www.toymoban.com/news/detail-713328.html

E tensorflow/compiler/xla/stream_executor/cuda/cuda_dnn.cc:425] Loaded runtime CuDNN library: 8.1.1 but source was compiled with: 8.6.0.  CuDNN library needs to have matching major version and equal or higher minor version. If using a binary install, upgrade your CuDNN library.  If building from sources, make sure the library loaded at runtime is compatible with the version specified during compile configuration.
