Hi, everyone! While trying to import pymatgen, it doesn’t show any errors. However, when attempting to import pymatgen.io.vasp.inputs, I encounter an error titled ‘ValueError: dictionary update sequence element #0 has length 1; 2 is required.’ Could you please suggest some solutions for this error? Am I missing something? Below are some details about the versions I am using.

Your .pmgrc.yaml is compromised. Open it in your text editor and look for keys without values. If you can't find the issue, try starting from a fresh .pmgrc.yaml.
