Cannot download files from a crashed run

Hi, could anyone tell me what’s going on with the API call?

I’m downloading a checkpoint through API from a run that crashed for some reason in Kaggle notebook, I promise the permission is the point of why the errors appeared(I own this project), and then the internet reason, I have tried in the other computer, and different notebook platform.

The below is my code:

api = wandb.Api()
run ="keahi/finalProjectCV&algorithm/ujp50jup")
file_name = "expt_6_prototype_vit_weightedSampling_dataset_ps16_tl12_numhead12_state_dict_epoch_60.pth"
file = run.file(file_name)

and then output as shown in the below:

wandb: W&B API key is configured. Use `wandb login --relogin` to force relogin
wandb: WARNING If you're specifying your api key in code, ensure this code is not shared publicly.
wandb: WARNING Consider setting the WANDB_API_KEY environment variable, or running `wandb login` from the command line.

The process of troubleshooting I’ve tried:

  • change platform → Not working
  • try to download a file from a different run → succeeded and very smoothly
  • try to download the same file from the dashboard directly → succeeded.

Looking forward to your help!!!
Thank you in advance.

Sorry, something that I missed is:

I’ve double-checked that the file name or run_id is correct.

Hi @keahixie thank you for writing in. Can you please try to print all file names as follows to see if there’s a matched output with the specified one?

api = wandb.Api()
run ="keahi/finalProjectCV&algorithm/ujp50jup")
for f in run.files():

Hi @keahixie we wanted to follow up with you regarding your support request as we have not heard back from you. Please let us know if we can be of further assistance or if your issue has been resolved.

Sorry, sir!
I’m quite busy these days because I’m in final exam week! I’ll send the feedback back in a week from now. Thanks for your understanding !!


Thank you for the update, @keahixie, and best of luck with your exams! Sounds good, let me know once you had time to look into this next week and we can take it from there.
