ImportError: cannot import name '_get_logger' Niftynet

Question

I'm trying to run Niftynet on my PC. but it keeps showing this error. I had a CPU version for tensorflow and it worked. After that I installed tensorflow-gpu and now it stopped working.

Please do note that import tensorflow as tf works fine so I'm not sure what do to now to solve this problem.

Traceback (most recent call last):

You need to install only tensorflow-gpu, and install the correct version for it. First uninstall everything:

pip3 uninstall tensorflow-gpu tensorflow

Then reinstall the correct tensorflow-gpu version

pip3 install --user tensorflow-gpu==1.12

The version is mentioned in the installation guide: https://niftynet.readthedocs.io/en/dev/installation.html
