Epochs + Training loss TensorBoard

Hello. I am new to Nvidia Modulus so I apologize if my questions are naive.

First I would like to make sure that the steps in NVIDIA Modulus represent iterations and not epochs? In that case what is the correspondance with the epochs?

Secondly I wonder how to change the frequency of training losses points in TensorBoard plots. In the custom file I change the rec_results_freq, but for me it has only an impact on the validation and inference plots. The training losses are always plotted every 1000 iterations. Is there a way to change that?

Thanks for your answer.
