Bump torch and transformers versions

[lapp0]

• Confirming the issue with torch reproduces in CI.
  • torch 2.0.1 resulted in test failure

In torch>=1.13.1,!=2.0.*, the OSError described in #568 is resolved.

fixes #568

We also should upgrade outlines version, as you cannot directly install outlines[serve] due to the dependency conflict between vllm==0.3.0 (requires transformers>=4.37.0) and outlines==0.0.26 (requires transfomers==4.36.2)

Thank you !

In torch>=1.13.1,!=2.0.*, the OSError described in #568 is resolved.

Any way we can simplify this by forcing torch >= X?

We also should upgrade outlines version, as you cannot directly install outlines[serve] due to the dependency conflict between vllm==0.3.0 (requires transformers>=4.37.0) and outlines==0.0.26 (requires transfomers==4.36.2)

You mean cutting a new release once this has been merged?

Will do.

Yep, due to the dependency conflict pip is resolving outlines[serve] to 0.0.19

Fresh venv:

pip3 install "outlines[serve]" -q

pip3 freeze | grep -P "(outlines|vllm)"
outlines==0.0.19
vllm==0.3.0

pip3 install "outlines[serve]==0.0.26"
ERROR: Cannot install outlines[serve]==0.0.26 and vllm==0.3.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    outlines[serve] 0.0.26 depends on transformers==4.36.2
    vllm 0.3.0 depends on transformers>=4.37.0
