TensorFlow on Windows: ImportError: no module named '_pywrap_tensorflow_internal'

Question

I am trying to make TensorFlow work on Windows. But after installing Python 3.5 and TensorFlow, I keep getting the following error when importing the TensorFlow module:

>>>import tensorflow
Traceback (most recent call last):
  File "C:\Users\amit\AppData\Local\Programs\Python\Python35\lib\site-packages\
tensorflow\python\pywrap_tensorflow_internal.py", line 18, in swig_import_helper

    return importlib.import_module(mname)
  File "C:\Users\amit\AppData\Local\Programs\Python\Python35\lib\importlib\__in
it__.py", line 126, in import_module

ImportError: DLL load failed: %1 is not a valid Win32 application.

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

Please indicate what is missing at my end so that the aforementioned runtime error can be removed.

Answer 1

This error occurs when one of the libraries (DLLs) that TensorFlow depends on cannot be found. To diagnose such an error, I wrote a script that you can download here ; running the script will print suggestions on what steps to take to fix the error.

• TensorFlow , DLL, , MSVCP140.DLL. Microsoft Visual ++ Redistributable Update 3, .

• TensorFlow GPU, , CUDA cuDNN . TensorFlow Windows CUDA 8.0 ( ) cuDNN 5.1 ( ). , cuDNN CUDA, %PATH%.

Answer 2

, . , CUDA 8.0 install cudnn64_5.dll cudnn64_6.dll.
