Hi!
I have a question about the size of the training model.
When we submit our trained models, is there a size limit for the models?
The normal maximum file size is 50MB.
For uploading the larger files, you can submit files of size up to GBs via git lfs.
In case you are not familiar with it can check the quick help doc here: How to upload large files (size) to your submission

Thank you for your prompt response!
Is there a capacity limit when using git lfs?
As far as I searched, the free version allows uploads up to 1GB.
If I pay $5/month, I can upload up to 50GB.
Is this correct?
No, I guess you looked for pricing @ GitHub.
We use our own-hosted version at gitlab.aicrowd.com, which you need to use for making submissions as well. It doesn’t have such limits or pricing and is free for the participants to use for the purpose of the AIcrowd challenges.

After I upload the model file using lfs, torch.load cannot read the file correctly.
_pickle.UnpicklingError: invalid load key, 'v'.
Hi @yue,
It is possible that your file isn’t pushed properly via git lfs, hence torch.load can’t read it.
