Getting error in siam-mot baseline submission "pack exceeded maximum allowed size"

I’m getting an error “remote: fatal: pack exceeds maximum allowed size” while pushing siam-mot baseline to the repo.


Hello @paulids

You need to use Git LFS to push the large files in your repository (your saved models, etc.,). You can find more information on how to use LFS here

I did that. List of the commands in order:

  1. git clone siam-mot starter-kit
  2. git remote add aicrowd{aicrowd_username}/airborne-detection-starter-kit.git
  3. git lfs install
  4. git lfs track “*.model”
  5. git add .gitattributes
    6 git commit
  6. git push aicrowd master

I haven’t changed anything other than those mentioned in the siam-mot template.

Hi @paulids,

The starter kit code already contains the model files in git-lfs etc, due to which you shouldn’t have face this issue. I assume you downloaded repository (not clone) and trying to recreate it?

The error you shared is happening because you have used example i.e. for *.model files directly.
While the SiamMOT baseline contains *.pth files.

You need to repeat the above commands for *.pth instead of *.model.

In case, you have already committed *.pth files without git-lfs in your repository, please use git lfs migrate command as well.

Yes, it should be *.pth. I made a mistake while posting the details. Started with a fresh clone, did everything as mentioned, still getting the same error.

Hi @paulids,

I suspect that you did git commit before doing git lfs install, etc.

But we can debug it in case you are still facing the issue, can you share output for following commands to help in debugging?

❯ git ls-files | xargs ls -l | sort -nrk5 | head -n 10
❯ git ls-tree -r -l --abbrev --full-name HEAD | sort -n -r -k 4 | head -n 10
❯ git lfs ls-files
❯ git --no-pager log --pretty=format:"%h%x09%an%x09%ad%x09%s" | head -n 10


As asked output of commands listed below

Hi @paulids,

Everything looks perfectly fine in your repository based on the outputs.

Can you share the exact error on doing git push ideally with the full command you are doing so?
It is still giving you “remote: fatal: pack exceeds maximum allowed size”? :thinking:

  1. git push aicrowd master
Locking support detected on remote "aicrowd". Consider enabling it with:

Hi @paulids,

Thanks for raising the issue and it is indeed an issue in default commands shared in the starter kit (happening because the total size of the repository has grown over time to be pushed at once).

You can push your repository using the below command as a workaround (only needed when pushing for the first time). We will meanwhile look for how to fix it cleanly as well.

❯ git rev-list --reverse master | ruby -ne 'i ||= 0; i += 1; puts $_ if i % 10 == 0' | xargs -I{} git push aicrowd +{}:refs/heads/master 

Thank you. I was able to push the repo.

This issue has been resolved, and the workaround is no longer needed!

Why was it failing?

The final pack file was too large to be pushed. Shifting data/dataset-playground.ipynb to LFS brought back the pack file size within acceptable limits.

But I’m still getting the same error!

The starter kit has been updated, and in order for this to work, you’ll need to clone it again.

Hi @nq1,

We had a storage issue in Docker builds yesterday but is resolved.
I missed re-queuing your submission and have done now. :raised_hands:

(seemingly resolved using !git lfs migrate import --everything)

Any commits with models are showing this error:
remote: fatal: pack exceeds maximum allowed size

(and work when commenting out the shutil.copyfile line below)

Code below:
!ssh -Tvvv

!apt-get install git-lfs
!git clone
!git lfs fetch --all
!git lfs track *.pth *.ipynb *.ckpt
shutil.copyfile(SOURCE_PATH, ‘model.pth’)
!git remote add aicrowd
!git lfs track *.pth *.ipynb *.ckpt
!git add .gitattributes
cd /content/airborne-detection-starter-kit
!git add .
!git commit -m ‘Commit’
!git push aicrowd master
