Hey there, thanks for reporting this— for anyone else who was encountering this issue, make sure you’re doing wandb login on the command line where you’re running your training script so that your machine is authenticated.

@tumbleintoyourheart just quick sanity check, make sure you are logging by pasting your api (wandb login your_api_key_here). I was logging in without my api key and that’s when I got that error logs, after correctly logging everything is working as expected.
