Python 3.12 installation crash

[AlexKurek]

shadems needs datashape:
Collecting datashape (from datashader<0.16.0,>=0.15.0->shadems==0.5.3->-r /opt/lofar/requirements3.txt (line 38))
datashape is not compatibile with Python 3.12:
blaze/datashape#245

(This is an upstream of tikk3r/flocs#100 (comment)).

Ugh, looks like we need to pin the Python version to <=3.11 until datashape is fixed... Thanks for the report!

[AlexKurek]

I dont think its getting fixed, last commit was ~5y ago.
BTW datashader now supports Python 3.12: https://github.com/holoviz/datashader/releases/tag/v0.16.1

[o-smirnov]

Hmmm, I'm confused where datashader<0.16.0 comes from then, we don't have an upper version pin in pyproject.toml. @Athanaseus any idea?

Hi @o-smirnov ,

This is because the caret (^) in semantic versioning (datashader = "^0.15.0") allows updates within the minor version range for versions below 1.0.0.
Valid versions: 0.15.0, 0.15.1, 0.15.2, etc., up to but not including 0.16.0.

Indeed, 0.16.1 supports Py3.12 and dropped Py3.8.
@AlexKurek please try with issue-124 branch.

Best regards

I checked, it works:

Hi @o-smirnov ,

Thanks! I learn something new every day.
