cannot import name '_collect_type_vars' from 'typing'

[GattiMh]

Hello!

Thank you for the tool.

I'm running it on a silicon Mac and I get this error when running the tutorial notebooks.

ImportError: cannot import name '_collect_type_vars' from 'typing' ([/opt/miniconda3/envs/qsartuna/lib/python3.11/typing.py](http://localhost:57643/opt/miniconda3/envs/qsartuna/lib/python3.11/typing.py))

When running:

import sklearn from optunaz.three_step_opt_build_merge import ( optimize, buildconfig_best, build_best, build_merged, )

Has anyone seen it before?
Many thanks

I think #38 is a similar issue

Yes this is a python version issue- QSARtuna is not currently compatible with 3.11+.

A wider large update for QSARtuna will be coming with 3.11+ support and much more - this will fix your issue.

In the meantime you can downgrade QSARtuna version or downgrade your python to 3.10 to keep the latest version

Thank you.

I downgraded to 3.10, which version should I use instead of QSARtuna? In the instruction is 3.1.4

[lewismervin1]

The latest version of QSARtuna is comptible with python3.10
