@bowang007 Can you move the auto plugin gen tests to a runner other than the one used for converter tests?

It looks like flashiner-python installation is problematic on CI. After resolving this issue, can you also check if this works for python 3.13 because we are going to support 3.13 as of 2.7 release while some packages may not be available for 3.13.

@zewenli98 I think this is expected since in the official doc it says it supports until python 3.12 here: https://docs.flashinfer.ai/installation.html

I updated the requirements.txt to get the python3.13 restriction @zewenli98

I saw some CI errors, not sure if that's related. I restarted the failed jobs. If they pass then LGTM
