Error in mos_prediction (for finding file `system_mos_all_trackwise.csv`)

Hi there,

I got an error while trying to execute mos_prediction downstream. The error said,

FileNotFoundError: [Errno 2] No such file or directory: '/groups/gac50538/VCC/VCC_2018/VCC2018_Results/system_mos_all_trackwise.csv'

After inspecting, the error is caused by the following lines in expert file.

https://github.com/s3prl/s3prl/blob/2bfd8485c2ba84654c993abf689621200acc6060/s3prl/downstream/mos_prediction/expert.py#L47-L51

That file (system_mos_all_trackwise.csv) is not given in the original dataset. So, I thought the authors make a script to generate that csv file from the data in the VCC 2018 dataset.

Also, the README in the mos_prediction is not complete and it differs from the current downloaded VCC databases for both 2016 and 2018 versions. The unzipped folder names are not the same per README. In the future, it will be better to provide a py file for preprocessing the dataset in the given path as in other downstream folders.

Any help will be highly appreciated, @RayTzeng ?

Hi,

Just to keep you updated. @RayTzeng is now working on preparing the csv file, and will push new commits to fix this soon. Thanks for reporting!

Thanks @RayTzeng for the fix!

I am confirming now mos_prediction downstream works without any issues after PR #287. The only specific requirement is it needs to be run on python3.8 (or maybe higher, but not lower, due to initial argument in itertools’s accumulate, the error happens in lower python version if this argument is skipped).

I will close this issue.
