MPRester Query Crashing

Hi, thanks for this report. Your code should now work as expected. The issue was that some of the elasticity data was including structure data in MP’s structure notation language (snl) format, and newer versions of pymatgen do not install the packages required to decode them into Python objects. To correct this, we

  1. no longer include structure information with elasticity data (this was never necessary; consider it a fixed bug in our database build process), and

  2. Warn MPRester users that they may need to install extras via

    pip install pymatgen[matproj.snl]

    (this warning will appear in the next release of pymatgen.

Thanks for the report.
