2129180716 PR_kwDOAMm_X85mld8X 8736 Make list_chunkmanagers more resilient to broken entrypoints 90008 closed 0     6 2024-02-11T21:37:38Z 2024-03-13T17:54:02Z 2024-03-13T17:54:02Z CONTRIBUTOR   0 pydata/xarray/pulls/8736

As I'm a developing my custom chunk manager, I'm often checking out between my development branch and production branch breaking the entrypoint.

This made xarray impossible to import unless I re-ran pip install -e . -vv which is somewhat tiring.

This should help xarray be more resilient in other software's bugs in case they install malformed entrypoints

Example:

```python

from xarray.core.parallelcompat import list_chunkmanagers

list_chunkmanagers() <ipython-input-3-19326f4950bc>:1: UserWarning: Failed to load entrypoint MyChunkManager due to No module named 'my.array._chunkmanager'. Skipping. list_chunkmanagers() {'dask': <xarray.core.daskmanager.DaskManager at 0x7f5b826231c0>} ```

Thank you for considering.

This is mostly a quality of life thing for developers, I don't see this as a user visible change.
