ERROR: Invalid requirement: 'transformers[sentencepiece,torch]<4.26>=4.23.0': Expected end or semicolon (after version specifier)

Description

Pip 24.1 rejects the multi-constraint version.
I don't know if this is the issue with PEP440 enforcement, but the error msg is certainly misleading.

pip version

24.1

Python version

3.10

OS

Ubuntu 22.04

How to Reproduce

Have transformers[sentencepiece,torch]<4.26>=4.23.0 in requirements.txt and python3 -m pip install -Ur requirements.txt.

You are missing a comma. The correct format is

transformers[sentencepiece,torch]<4.26,>=4.23.0

[xkszltl]

Yes, I know, the problem here is that format was previously supported, and I cannot find any doc explicitly saying "this is deprecated and should be replaced by something else". All I found is PEP440 syntax doesn't include this.

but the error msg is certainly misleading.

I beleive the error message comes from packaging , while it isn't exactly identifying what you are missing, it is pointing to where the error is:

ERROR: Invalid requirement: 'transformers[sentencepiece,torch]<4.26>=4.23.0': Expected end or semicolon (after version specifier)
    transformers[sentencepiece,torch]<4.26>=4.23.0
                                     ~~~~~^ (from line 1 of requirements.txt)

I'm not an expert on how pip and packaging interact, but for improvements to the error message I beleive you will need to raise an issue over there.
