How do I troubleshoot this error? I have never used the API before.

It’ll be hard for us to pinpoint the issue without a code snippet indicating the specific code you’re trying to execute. From what I can glance from the traceback, the following line suggests that you’re running the code with a numpy installation/version different from the one you used when installing emmet-core.

Value error, numpy.dtype size changed, may indicate binary incompatibility.

The code I’m trying to run is

from mp_api.client import MPRester

Just that one line.

I have no idea when emmet_core was installed, presumably when I did pip install mp_api earlier today? The numpy installation would be older.

Do I need to uninstall emmet_core and reinstall it?

Try to set up your python dependencies in a new and dedicated conda environment.

This eventually worked. I think something else besides emmet-core had an issue, but the fresh environment with just numpy, mp_api, and dependencies installed worked.
