ImportError: cannot import name 'MutableSet' from 'collections'

[GrantFoley]

I am attempting to install from PyCorrFit from source, but this error message keeps popping up. How should I got about fixing this issue?

Do you have the full traceback? Looks like some third-party module does not support the latest Python version. MutableSet is in collections.abc.

Here is the most recent traceback when I try to run PyCorrFit using the python -m pycorrfit command

Right, I get the same error fresh in pip. As a short-term fix, change the import statements in those files to collections.abc.

Which version of lmfit do you have? In version 1.1.0, this import is not there anymore: https://github.com/lmfit/lmfit-py/blob/1.1.0/lmfit/model.py

[GrantFoley]

I currently have lmfit 0.9.2 installed.

[paulmueller]

OK, it's probably that. You have to upgrade lmfit.

[GrantFoley]

Ok I think that did it. PyCorrFit was able to open, and I was able to load my .cor file into it. Thanks to both of you for all of your help. I will let you know if any more issues arise.
