No Module Named '_pywrap_tensorflow_internal&#

Question

I have the same problem as in the similar question and tried the proposed solution, but it did not work. Below you can find the stacktrace. I am on Windows 10 x64 with Python 3.5.2 and GPU NVidia Geforce 1050. I also checked the TensorFlow site for common errors.

Failed to load the native TensorFlow runtime.

above this error message when asking for help.

I am working on a research problem within Algorithmic Trading and need GPU support to speed up learning. I very much welcome any solution to this problem.

Answer 1

Most of the time, this is due to missing DLLs (or missing paths thereto).

@mrry mentionned here his helpful script to diagnose this kind of error, which you can find there.

Answer 2

Go to cuda\bin directory in file explorer rename the single dll file to cudnn64_5.dll Done.
