I installed pymc4 in google colab and got this error when importing the library

!pip install pymc==4.0.0
import pymc as pm

RuntimeError: 
Could not import 'mkl'.  If you are using conda, update the numpy
packages to the latest build otherwise, set MKL_THREADING_LAYER=GNU in
your environment for MKL 2018.

If you have MKL 2017 install and are not in a conda environment you
can set the Aesara flag blas__check_openmp to False.  Be warned that if
you set this flag and don't set the appropriate environment or make
sure you have the right version you *will* get wrong results.

This is a known issue with Aesara on colab, you can use this magic command before importing pymc or aesara to fix it: %env MKL_THREADING_LAYER=GNU
