music-demixing-challenge-starter-kit's Issues

Better error handling

we assume that the sample rates of the signals and the length of the references and estimates are the same. However often, users might not be aware of this and it would make sense to warn them already in the local test submission.

we have:

music-demixing-challenge-starter-kit/evaluator/music_demixing.py

Lines 95 to 96 in 4cd3be8

reference, _ = sf.read(reference_file)
estimate, _ = sf.read(estimate_file)

I think we should add

  • a check of the sample rates (the second argument _) these should the same (int(reference_rate) == int(estimate_rate))
  • a check of the shape of the files (reference.shape == estimate.shape)

Struggling to get setup

Hi,

I'm having trouble making a test submission using the repo.

I am working in a fresh nvcr.io/nvidia/cuda:11.3.0-cudnn8-runtime-centos8 docker image. Following that I have:

  • Installed GCC, git, nano via Yum.
  • Installed miniconda.
  • Generated SSH key and added it to my profile.
  • Git cloned the repo & installed requirements.
  • Changed the aicrowd.json to my username.
  • Run the below:
# Add AIcrowd git remote endpoint
git remote add aicrowd [email protected]:errorfixrepeat/music-demixing-challenge-starter-kit.git
git push aicrowd master

This gives me the error:

The format of the wav file is unknown.

I get a RuntimeError when I run the fourth Try out random prediction codebase present in test.py. in Setup.
I found that the format of the wav file in data/test was unknown.
I opened this wav file in audacity, but it showed up as a file of unknown format.
Is this wav file the correct one?
Sorry if this is my mistake.
The full text of the error is below.

README submission template for mediocre submissions

Hello!

Not to be too down on myself - I'm happy with my work and progress - but my place in the leaderboard is pretty low (lower than 30) - i.e. it may not be too interesting of a model to be published, etc. Do I necessarily need to fill the special submission README?

https://github.com/AIcrowd/music-demixing-challenge-starter-kit/blob/master/README_SUBMISSION_TEMPLATE.md

Is it only for the top 10 submissions that will be included in the final writeup/summary?

Error cloning repo

Hi

When I try to clone the repo, I get an error when it gets to the data/test/Mu - Too Bright/bass.wav file

fatal error: unexpected signal during runtime execution
[signal 0xb code=0x1 addr=0xb01dfacedebac1e pc=0xca0b0]

I have already seen the posts that suggest trying git lfs pull, which I have tried without joy. See below:

fatal error: still in list

Git version is 2.31.1 on macOS 10.15.7.

Any help would be much appreciated.

Cheers
