The token has not been saved to the git credentials helper. Pass `add_to_git_credential=True` in this function directly or `--add-to-git-credential` if using via `hf`CLI if you want to set the git credential as well.
Token is valid (permission: write).

Login successful.
Note: Environment variable`HF_TOKEN` is set and is the current active token independently from the token you've just configured.

Script: train_pi0fast.py
Train args: --dataset fixed_motion_simple --steps 5000 --batch-size 6 --lr 5e-5 --save-freq 1000 --push-to-hub --num-workers 8 --task-text move arm back and forth
The following values were not passed to `accelerate launch` and had defaults used instead:
`--num_machines` was set to a value of `1`
`--mixed_precision` was set to a value of `'no'`
`--dynamo_backend` was set to a value of `'no'`
To avoid this warning pass in values for each of the problematic parameters or run `accelerate config`.
