win10 install TensorFlow 2.2.0

Enter the following command on the cmd command line

 pip install tensorflow==2.2.0 -i https://pypi.tuna.tsinghua.edu.cn/simple

Since my cuda version is 10.2, the TensorFlow version I downloaded is 2.2.0.
If you want to download other versions, you can change 2.2.0 of the above command to the corresponding version number. If you want to download the GPU version, the command is as follows

pip install tensorflow-gpu==2.2.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
