ImportError: cannot import name 'get_module' from 'plotly.optional_imports'

TL;DR: plotly 6.2.0 was a broken release; its own submodules cannot import. Move off 6.2.0 (upgrade to the fixed release or downgrade to 6.1.x) and the import works.

The error

ImportError: cannot import name 'get_module' from 'plotly.optional_imports'

Fix it

1. Check you are on the broken release:

   pip show plotly | grep Version

Expected: shows 6.2.0.

1. Upgrade past it:

   pip install -U plotly

Expected: installs a release newer than 6.2.0.

1. If the fixed release is not out for your index yet, downgrade instead:

   pip install "plotly==6.1.2"

1. Verify:

   python -c "from plotly.subplots import make_subplots; print('ok')"

Expected: prints ok.

When this applies

Use this when any plotly import fails with the get_module error and the installed version is exactly 6.2.0.

When it does not apply

If your plotly version is not 6.2.0, this is a different problem; check for a corrupt install. If the error names another symbol, look it up separately.

Compatibility

plotly 6.2.0 only. Both 6.1.x and the fixed 6.2.x+ releases import fine.

Root cause

The 6.2.0 release shipped with an internal refactor of plotly.optionalimports that dropped the getmodule helper while other submodules still imported it, so the package could not even finish importing itself.

Edge cases

If pip keeps resolving to 6.2.0, pin explicitly to the version you want in requirements. In CI, unpinned plotly can silently pick up a bad release; pinning avoids the surprise.
