ImportError: cannot import name 'MPRester' from 'pymatgen' (unknown location)

I am using python 3.8.5 in jupyter notebook. I am getting an error while doing:

from matminer.data_retrieval.retrieve_MP import MPDataRetrieval
mpdr = MPDataRetrieval(api_key='my_api_key')

The error is :

ImportError: cannot import name 'MPRester' from 'pymatgen' (unknown location)

I have installed pymatgen and matminer. Why did this error occur?

It was moved to from pymatgen.ext.matproj import MPRester.

So the matminer code is outdated, try updating it and/or downgrading your pymatgen package to an older version.

see pymatgen docs.
