  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

The error persists when using pip install --no-cache-dir --extra-index-url https://pypi.nvidia.com cuml-cu11 or when targeting specific cuml-cu11 versions. It used to work well until a few days ago. Looking for help!

the issue disappeared for a few days, but now it’s back :(
still looking for help! thanks
