@ftshijt Do you know how I can fix this issue?

[sw005320]

Are these models using s3prl?
If so, the test should include it in the installation stage.

It is a little bit difficult decision as we want to make espnet_model_zoo installation as light as possible.
But anyway, can you first try it?

[siddhu001]

They do use s3prl. Sure I will do that!

[sw005320]

Can you fix the conflict?

[siddhu001]

Sure! I will work on it now!

I think the earlier error due to ASR streaming model has been fixed now with the help of previously merged pull request - #57.

I have fixed the import ordering. I think after this pull request is merged - espnet/espnet#3928, the test should hopefully pass.

The issue seems to be connected to facebookresearch/fairseq#1400. There seems to be some issue with pytorch hub cache. I will try using workaround mentioned in this issue.
