I get "OSError: [WinError 6] The handle is invalid" when trying to run pysph examples about pysph

@githubrho -- you will need to install both compyle and pysph from github. I apologize for not pushing out releases for these and these are long pending but my semester has become never-ending and I have not had a break for a while. For now please try the following:

pip uninstall pysph compyle
pip install https://github.com/pypr/compyle/zipball/master
pip install https://github.com/pypr/pysph/zipball/master

Hope this helps.

@prabhuramachandran
Thanks for your reply, I totally understand, I am a professor myself - actually trying to work with some undergrads to apply SPH to solar system evolution. Cheers

@githubrho -- great, thank you!

got the following:

ERROR: spyder 5.0.3 requires pyqtwebengine<5.13, which is not installed.
ERROR: conda-repo-cli 1.0.4 requires pathlib, which is not installed.
ERROR: spyder 5.0.3 has requirement pyqt5<5.13, but you'll have pyqt5 5.15.4 which is incompatible.

I can probably live with using an editor other than spyder, but is the pathlib installation absolutely necessary?

also unable run examples:

...File "pysph\base\particle_array.pyx", line 1, in init pysph.base.particle_array
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

fixed: uninstalled then reinstalled numpy
