Facing issue with installation of witwidget (google what-if too) on Windows in Anaconda

Question

I am facing issue with installation of What-If tool.

Step 1: pip install tensorflow (This completed successfully)

Step 2: pip install witwidget (this completed successfully)

Step 3: jupyter nbextension install --py --symlink --sys-prefix witwidget (this failed and the error log is given below)

Environment: Windows 10 Python version: 3.7.0

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

Answer 1

I was able to resolve the issue and it seems it was primarily due to tensorflow version. Well here are the steps I followed to install witwidget on my Windows laptop with Anaconda Python (v3.7)

pip install pyhamcrest pip install google-auth conda update wrapt

Now is the important part. You need to uninstall tensorflow, if it is version > 2.0. So try running this command to install tensorflow v 2.0

pip install tensorflow==2.0.0

Then execute these commands and you are good to go

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

Thanks !
