Import error of GlassNet in 0.4.2

[charlesll]

Hi, we updated GlassPy to 0.4.2 (from 0.4.0), and since then cannot load GlassNet. It seems that a model file is missing in 0.4.2.

The problem is solved downgrading to 0.4.0 for now. We did not test if it replicates in 0.4.1, but in 0.4.2 we replicated the problem on two different installs on two Mac OS computers.

The exact error message is the following:

FileNotFoundError Traceback (most recent call last)

Thanks a lot @charlesll! It should be fixed now in v0.4.3. Could you please test and report back?

[charlesll]

I now get another error, from a file not found at module import:
FileNotFoundError: /Users/charleslelosq/anaconda3/envs/ml/lib/python3.9/site-packages/glasspy/chemistry/data/chemical_properties.csv not found.

Thanks again for your input, @charlesll. For now, please try to install GlassPy using pip install --upgrade git+https://github.com/drcassar/glasspy, it should work. I am sorting out some problems to upload the current version to PyPI as it is above the allowed limit (100 Mb).

[charlesll]

I confirm, it works!

[drcassar]

Thanks! I will leave the issue open until I sort out how to work with the size limit on PyPI.

Hi @charlesll, if possible, could you please test installing GlassPy v0.4.4 from pip (pip install --upgrade glasspy)? This new version now downloads SciGlass data from Zenodo as soon as it is needed (instead of shipping the data with the module). I tested this on linux and it seems to be working, but I do not have access to a Mac OS computer to test.

[charlesll]

Hi @drcassar, install is good on Mac OS 13.4.1 (Intel processor). GlassNet predictions work. Getting data from SciGlass effectively download SciGlass and it seems to work well.

[drcassar]

Great, thanks a lot @charlesll! I will close this issue as it seems to be solved now.
