Hi MelancholyBeetle72 , that's a very interesting case. I can totally understand how storing a model and then immediately renaming it breaks the upload. A few questions, is there a way for pytorch lightning not to rename the model? Also I wonder if this scenario happens a lot (storing model and changing it) . I think the best solution is for Trains to create a copy of the file and upload it in the background. That said the name will still end with .part What do you think?
