CodePudding user response：

I googled the error message and found this thread as the first result:

That could be because you still have the old theano installed (instead of the new fork theano-pymc). Try to uninstall PyMC and Theano and install PyMC again.

CodePudding user response：

First you have have to open cmd as administrator mode. then you type those command first you update all packages using conda update --all then used those command

conda install -c conda-forge pymc conda install -c
conda-forge/label/gcc7 pymc conda install -c
conda-forge/label/cf201901 pymc conda install -c
conda-forge/label/cf202003 pymc
