[AutoGPTQ] Add correct installation of GPTQ library + fix slow tests

[younesbelkada]

What does this PR do?

Per the instructions of installing auto-gptq library we need to slightly update the Dockerfile otherwise it will install the 0.3.2 version which is not compatible with the integration

Will also update some expected values to make the slow tests pass

Can confirm the Docker image is built successfully

works for me. Thank you for confirming the build is successful.

So basically we want to install the same version but with cu118 support, right?

The documentation is not available anymore as the PR was closed or merged.

Can confirm the slow tests now pass in the docker image

So basically we want to install the same version but with cu118 support, right?

It is slightly trickier than that, auto-gptq listed in pypi does not contain the latest supported versions (>= 0.4.1), one needs to install that directly through the command that I have shared. Also that way you get the pre-built wheels instead of building auto-gptq at each install (which is the case right now if you do pip install auto-gptq)

LGTM ! Thanks for checking that the image is built correctly :)
