For some reason, mv /testbed causes the conda environment to break (most likely because some packages are installed inside docker are based on the absolute path of /testbed)

Lets do this, tbh I was idly wondering if mv isn't a bit harsh 👌

Oh yeah this should also work I think, because we're collecting diff directly in workspace/xxx, thanks! Not sure why I didn't see any issues when running eval in my PR.

Can you help post some error messages here for reference @xingyaoww? Just to trace back when the cp -r might causes some other weird behaviors...

I don't really have specific error messages beside the agent tries to conda install astropy because it fails to run python reproduce.py due to dependency issue 😓
