ImportError: Dependencies for InstructorEmbedding not found.

[namin]

Hi,

After a recent upgrade, I am getting the error: ImportError: Dependencies for InstructorEmbedding not found.

What package should I be installing to fix this error?

Thank you.

Thanks for report the issue, the package known as InstructorEmbedding.

Thanks for the response. Something seems wrong: even after I ensure the package is installed, I get the same error.

Oh, OK. It works when I also install sentence_transformers. Thanks!
