Unable to run what-if tool commands in jupyter notebook in Anaconda environment on Windows10

[agarwal...@gmail.com]

Hi,

I am trying to do what-if tool setup in my windows10 machine

I am following the instructions given at : https://github.com/pair-code/what-if-tool

pip install witwidget
jupyter nbextension install --py --symlink --sys-prefix witwidget
jupyter nbextension enable --py --sys-prefix witwidget

First command(pip install witwidget) is successful but following command throw error as below

(base) C:\Users\paresh.agwl>jupyter nbextension install --py --symlink --sys-prefix witwidget

I am not sure what is this issue and missing dependencies in my system. I tried same setup in Ubuntu 18.04 installation was successful.

Please help me to resolve this issue as I am struck and unable to use what-if tool

Thanks for reaching out. This seems to be an error with the TensorFlow installation not working correctly inside your anaconda environment on Windows (witwidget has a pip package dependency on tensorflow). Have you previously used tensorflow in this environment before? I imagine you would get the same error in your environment if you pip installed tensorflow and tried to do an "import tensorflow" statement in a python module.

Here is a stackoverflow link of others dealing with similar-sounding tensorflow install issues on windows and possible solutions: https://stackoverflow.com/questions/42011070/on-windows-running-import-tensorflow-generates-no-module-named-pywrap-tenso

Let me know if any of the possible solutions in that link help you get past that error.
