How do I resolve this TensorFlow error in PyCharm?

Question

tensorflow_installation_test.py

import tensorflow as tf
import os
os.environ["CUDA_VISIBLE_DEVICES"] = "-1"

print(tf.__version__)

the following is the output:

How do I fix this?

Answer 1

So according to this link on StackOverflow, this is not a problem just for you. The real clue to your error is the WinError 126. Some causes I could find online listed here on ErrorTools. My recommendation would be to perhaps, if you are using Anaconda environments, to create a new environment and install TensorFlow there and see if it works. If it does not, perhaps there is something wrong with your DLLs.

Another option, in that case, would be to follow the stack trace that is laid out to you to debug until you reach this line: self._handle = _dlopen(self._name, mode) in __init__.py under the ctypes directory. At that point, you can examine what is the value of self._name and see if it matches any of the problems outlined on the linked StackOverflow question above.

If you are unsure where to find all of these files for future debugging on your own, I would recommend that you use Everything by VoidTools since it performs much quickers searches than File Explorer.
