That is, the gpu version of tensorflow cannot find a dll file of cuda and cannot perform GPU acceleration
The first possibility: cuda version does not match tensorflow version
It can be seen that the version of cuda10.1 required by cuda, so the version of cuda10.2 cannot be used.
You can try to change the dll file name;
it is best to download the cuda10.1 version;
tensorflow and cuda matching information:
https://tensorflow.google.cn/install/source
The second possibility: cuda version matches, tensorflow cannot find the dll file
Then you need to confirm whether the dll file is in the corresponding path:
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin
If it exists,
add this path to the system environment variables and try again.
