IOPub Problem when saving multiple PyTorch models

I implemented the pix2pix model and saved the result of each epoch for the discriminator and the generator in the same file by following:

SAVING AND LOADING MULTIPLE MODELS IN ONE FILE USING PYTORCH

but when the model is training a warning arise said that:

IOPub message rate exceeded.
The notebook server will temporarily stop sending output
to the client in order to avoid crashing it.
To change this limit, set the config variable
`--NotebookApp.iopub_msg_rate_limit`.

Current values:
NotebookApp.iopub_msg_rate_limit=1000.0 (msgs/sec)
NotebookApp.rate_limit_window=3.0 (secs)

The model is still training but I want to know that is training properly, and thanks in advance.

Note: I’m using a Kaggle notebook.
