Numpy+parmed error during dash-bio import

[celia-lm]

These error happens during import dash_bio in Python 3.12 if numpy>=2.3.0 because of this change:

Removed the np.compat package source code (removed in 2.0)

(gh-28961)
Ref: https://numpy.org/doc/stable/release/2.3.0-notes.html#expired-deprecations

The fix would be to update the dash-bio code to adhere to numpy>=2.0.0.

In the meantime, a workaround is to fix/specify numpy<2.3.0 in the environment where you are running this code.

Environment to reproduce the issue:

• Python 3.12
• requirements.txt:

dash-bio==1.0.2
# these two should get installed automatically as dependencies unless there are other (different) existing versions
numpy>=2.3.0
parmed==4.3.0

The error happens at the import step, so no need to use a specific Dash app. If needed, any sample app from the docs can be used: https://dash.plotly.com/dash-bio/molecule2dviewer

No version of ParmEd is specified in the current dependencies of dash-bio: https://github.com/plotly/dash-bio/blob/v1.0.2/setup.py#L36

In any case, in Python 3.12, only ParmEd >=4.2.1 is available: https://github.com/ParmEd/ParmEd/releases/tag/4.2.1
