Describe the bug While running marie container `3.0.22-cpu' we get in the logs.

process completes but it looks like we are not compiling the models.

Describe how you solve it N/A

[fuseraft]

Is g++ installed in the container? Also this torch issue might be related.

You could also try setting the TORCH_INDUCTOR_INSTALL_GXX environment variable and pytorch inductor will try to install gcc (along with g++) using conda.

[gregbugaj]

I do have g++ installed in container. I will check out details on the task referenced.

Is this still an issue? I built and ran 3.10-cpu and it worked fine.
