How are model checkpoints packaged?

[hermancollin]

How are model checkpoints usually dealt with? For example in https://github.com/ivadomed/model_seg_sci/tree/main I don't see any models. They are not listed in the repo assets either

Great question. Here are two examples of model checkpoints:

• https://github.com/ivadomed/model_seg_ms_mp2rage/releases
• https://github.com/ivadomed/model_seg_mouse-sc_wm-gm_t1/releases

The idea is to refer to these checkpoints in 3rd party software using these models. For example in SCT we have this file that does that.

Thanks @jcohenadad. The model_seg_mouse-sc_wm-gm_t1 example is what I was looking for. In short, this was the content of the asset: Only the selected fold is included, but validation results are also present. The filesize is further reduced by only keeping best or final checkpoint.

I was a bit concerned about how large the assets in a release can get (because nnUNet models are heavy). But their documentation says that:

Each file included in a release must be under 2 GiB. There is no limit on the total size of a release, nor bandwidth usage.

(which is good)
