running simply this:
from mp_api.client import MPRester
produces
ValidationError: 23 validation errors for EmmetSettings
What exact versions of each mp-api/dependency work together? can someone paste in their requirements file?
Hi @edwardghbaker,
Running a pip install --upgrade --no-cache-dir mp-api in a fresh conda environment works on my end.
The current versions pip will resolve to are mp-api==0.45.12 and emmet-core==0.86.0rc1
Running the same thing with the latest dev release (mp-api==0.45.13rc4) is also working on my end.
Hello, sorry to ask again but im getting a new error with mp-api.
Im trying to make a pourbaix diagram, so I have the mpcontribs-client package too.
with MPRester(my_api) as mpr:
entries = mpr.get_pourbaix_entries([“Cu”])
NB there is an indent but it just doesnt show here.
The “entries” line errors with the following code:
AttributeError: ‘FieldInfo’ object has no attribute ‘_copy’
pip install --upgrade --no-cache-dir mp-api worked to solve the first problem 
so i can import the MPRester package now.
@edwardghbaker Do you happen to have the full traceback for the error? Which mpcontribs-client version are you running? Did you install all dependencies in a fresh environment?
Hi @tschaume,
thanks for helping me with this one.
It is in a fresh environment, version: mpcontribs-client==5.10.4
Ive copied the full error traceback below:

We’ve been working to resolve compatibility issues with pydantic, can you try:
pip install mp-api==v0.45.13rc5 emmet-core==v0.86.0rc1 pydantic==2.12.3
to see if that fixes it?
