Pip install fails due to numpy/PIL error

[nhmasterolt]

Hello,

I just tried installing sfepy on windows 11 using various python versions from 3.7, 3.8, 3.9 and 3.12. However, all raised
"AttributeError: module 'numpy.typing' has no attribute 'NDArray'";
If I got it right, the issue lies in some sub-module taking a numpy version <1.20 while >1.20 is installed. Unfortunately, however, trying to install different numpy versions before installing sfepy does not resolve the issue, and my installation fails.

Best,

Hello, maybe try the installation in a fresh virtual environment, so that no version clashes occur. Are you using conda?

Hello, thanks for your answer.

I'm trying pip in a fresh venv.

As an alternative to installing from pypi directly, cloning the source code, version sfepy-release_2024.2, and install using pip install -e . I can successfully install, but running sfepy-test, I run into

ImportError while importing test module '\tests\test_dg_field.py'.
Hint: make sure your test modules/packages have valid Python names.

Can you try just pip install ., i.e. no editable install?
