Hi, seems that I made a silly mistake: the tensorboard in my virtual environment was not installed properly. Now I make it right and it works (without Jupyter).  Also I’ve tried to use it in a remote Jupyter Lab, and the tensorboard works, too. But I’m not sure how the environment is set up because it is provided by a cloud service providers. Maybe you can add some custom log callback to log your loss in a text file and visualize it manually?
