Pin Numpy: numpy<2.0.0, Prevent ModuleNotFoundError

[lapp0]

Addresses: #976

Fixes vllm-project/vllm#5582

We should close 976 after we fix Outlines to be compatible with Numpy >= 2.0.0, which this PR doesn't do.

Problem

Cannot import outlines due to outlines/base.py importing from numpy.lib.function_base import ( which no longer exists in numpy 2.0.0.

Temporary Solution

Pin numpy<2.0.0

Major revision bumps (1.x.x -> 2.x.x) always have breaking changes. Should the other requirements not be limited in this way as well?

That would have to wait, though. This issue affects all scripts and modules that import outlines, and should be merged ASAP.

Good idea, I created an issue for that #981

Hi @rlouf, could you please make a new release? vLLM imports outlines for the OpenAI server and is currently broken because of this Numpy issue.

Will do right now
