How can I check the loss during pretraing huggingface/transformers

 thanks in advance.
I trained roberta model from scratch.
But I cant  check the training loss during pretraining.
I did it by refering below link.
https://colab.research.google.com/github/huggingface/blog/blob/master/notebooks/01_how_to_train.ipynb
in above link, loss is printed every 500 steps,
but when I did, there is no loss print.

training loss should be printed every 500 iteration, but there is no log in pretraing.
(parser.add_argument("--logsteps", help="logging steps", type=int, default=500)<|||||>Hi! This wasn't intentional, so we've fixed it with #6097. If you rerun the script, you should see the losses now.
