cannot run train_with_warp_drive

[Emerald01]

I meet a few errors when running train_with_warp_drive,

one is from scripts.run_unittests import import_class_from_path seem not good, it will complain scripts cannot be found in module, so I remove scripts., I believe the Python path of this lib shall be cleaned up a little bit

the 2nd problem is when I run this training script, the first time is fine, but the second time and on I constantly got this error, I believe it comes from the package importer, can you check on that?

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Thanks for pointing this out @Emerald01 , we really appreciate it. Could you please give more information, like a list of the versions of the modules and the OS that you are using so that we might be able to replicate this issue?

Besides, did you try following the tutorial notebook via Colab? Are the issues also showing up here?
