I am using the doped package and some parts require the old version of MP, but after adding the key, I keep getting an error."ValueError: No API key (either api_key parameter or ‘PMG_MAPI_KEY’ in ~/.pmgrc.yaml or ~/.config/.pmgrc.yaml) was supplied. This is required for automatic competing phase generation in doped, as detailed on the installation instructions:

Moving this to the pymatgen forum since the doped package seems to be using pymatgen’s MPRester.
