test installation under MS-Windows

[gdmcbain]

There have been some infrastructural changes recently, so it was thought to be a good idea to check that installation remains as smooth as it has been under MS-Windows. I'll do this and report back.

In an Anaconda PowerShell Prompt (Miniconda3), with conda version 4.8.5, Python version 3.8.3.final.0:

conda deactivate
conda create -n skfem-msw python
conda activate skfem-msw
pip install scikit-fem

This brings in scikit-fem 2.2.1, meshio 4.3.0, numpy 1.19.2, scipy 1.5.2

git clone [email protected]:kinnala/scikit-fem
python scikit-fem\docs\examples\ex01.py

This raises ModuleNotFoundError for matplotlib. I could have done pip install scikit-fem[full]. (I think it's right that matplotlib is not brought in by default; it brings in a lot of other stuff and might not be needed when skfem is used as an internal library.) Pressing on.

pip install matplotlib
python scikit-fem\docs\examples\ex01.py
mspaint .\scikit-fem\docs\examples\ex01_solution.png

Looks good.

conda install pytest-xdist
pytest -n auto .\scikit-fem\tests\

Results:

Let's try that again.

pip install pacopy==0.1.2 pygmsh<7
pytest -n auto .\scikit-fem\tests\

This time:

FAILED scikit-fem/tests/test_examples.py::TestEx32::runTest - ModuleNotFoundError: No module named 'pyamg'

[gdmcbain]

One more:

pip install pyamg
pytest -n auto .\scikit-fem\tests\

which gives

That TestEx09 passes after installing PyAMG is pure #469.

[gdmcbain]

TestEx32 is missing Gmsh. It'd be nice to rewrite the test so that it didn't need that; see #490. (I'm not sure whether #491 would work under Windows though. My experiences with Docker and Windows have been very rocky.)

pip install gmsh
python .\scikit-fem\docs\examples\ex32.py

No good, still FileNotFoundError for Gmsh. (I suspect that that's a pygmsh bug as gmsh 4.6.0 is on $env:PATH and can be invoked from the Anaconda PowerShell Prompt. No bug fixes for pygmsh<7 though.)

[gdmcbain]

Summary:

• With pip install pacopy==0.1.2 pyamg, the suite passes except TestEx32.
• ex32 is an upstream Gmsh or pygmsh<7 problem generate ellipsoidal ex32.mesh in other than pygmsh #490, not really a scikit-fem concern?
• A reminder to look at ex09 regression in build_pc_ilu in ex09 #469.
