Installing error

[KGhorbani]

Hello,
Thank you for developing this Python package for the SPH method. I tried installing pysph on Windows 10 using "pip install pysph", but encountered the following error:

There are some fixes that are pending. Meanwhile, could you try this in a fresh python 3.11 venv:

pip install --upgrade pip setuptools wheel
pip install numpy cython h5py
pip install https://github.com/pypr/cyarray/zipball/master
pip install https://github.com/pypr/compyle/zipball/master
git clone https://github.com/pypr/pysph.git
cd pysph
git fetch origin pull/400/head:interim
git switch interim
pip install -r requirements.txt -r requirements-test.txt
pip uninstall -y numpy
pip install oldest-supported-numpy
pip install -e . --no-build-isolation

I am not sure if it should be done like this, but this might get it going for you until the fixes are done, I guess.

Cheers
Navaneet
