Cannot import pymc3 module due to geweke

It looks like the issue is related to the version of python (3.6) you are using and a dependant library pyMC use called arviz.

Make sure you uninstall the old version and follow the following steps to reinstall everything.

Uninstall using :

• pip uninstall Theano Theano-PyMC PyMC3

Make sure you remove theano left overs by running :

sudo rm -fr the_python_path_u_are_using/lib/python3.6/site-packages/theano

And then install arviz with :

• pip install arviz==0.10.0

And finally, install pymc3 again.

pip install pymc3

Try again and it will work.

It depends on your environment

For Anaconda: Uninstall “arviz” Use: conda uninstall arviz

Now, install the latest version of “arviz” For today, it is version 0.11.1 Use:

conda install arviz==0.11.1

For Non Anaconda environments: Uninstall “arviz” Use: pip uninstall arviz Now, install the latest version of “arviz” Use:

pip install arviz==0.11.1

My environment: Ubuntu 18.04, Python 3.7.10

I have similar problem, after read this error at https://discourse.pymc.io/t/attributeerror-module-arviz-has-no-attribute-geweke/6818/4. The following commands solve the problem of AttributeError: module 'arviz' has no attribute 'geweke'

pip uninstall arviz
pip install arviz==0.11.0
pip install pymc3==3.10.0
