2、If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.

升级或者降级

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn protobuf=3.20.1

3、cannot detect archive format
ERROR: Cannot determine archive format of C:\Users\XXX

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

改成

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn xxx

4、permission deny

权限错误：[errno 13]权限被拒绝

错误原因：

文件无法打开，可能产生的原因是文件找不到，或者被占用，或者无权限访问，或者打开的不是文件，而是一个目录。

把打开的文件关闭。。。。

5、Cannot convert a symbolic Tensor (lstm/strided_slice:0) to a numpy array.

原因是 tensorflow 和 numpy 版本不兼容的问题

activate TF2.1
pip list
pip uninstall numpy
python -m pip install numpy==1.18.5

6、在加载训练之后的hdf5模型时，‘str’ object has no attribute ‘decode’

AttributeError: 'str' object has no attribute 'decode'

将h5py==2.10.0版本改为：

C:\Users\Administrator>python -m pip install h5py==2.10 -i https://pypi.tuna.tsinghua.edu.cn/simple
