Hi @sw005320 @ftshijt ,

One of the CI test of the previous test set (71a08ad) failed with the following error:

However, all the other CI tests passed this stage of accessing this google drive link. So I am guessing it was a temporary issue? If there is something we need to do to fix it, please do let us know!

[sw005320]

LGTM.
Once it passes the CI, I'll merge it.

[bharaniuk]

@sw005320 It appears that the CI is failing due to the google drive access issue again.

This pull request is now in conflict :(

[sw005320]

Can you merge the master?
We fixed the CI issue.

@sw005320 I believe that a recent PR has a PEP issue as seen in the error message
egs2/zh_openslr38/asr1/local/check_train_test_duplicate.py:35:89: E501 line too long (94 > 88 characters)
It seems to be from this PR which is why our tests seem to be failing.

[sw005320]

Thanks a lot.
It seems like that.
Our CI was recently broken and I overlooked the issues in #4181 due to that.

[ftshijt]

Could you merge the latest master branch to fix the CI?

[ftshijt]

LGTM! Many thanks
