PanickyMoth78 'tensorboard_logger' is an old deprecated package that meant to create TB events without TB, it was created before TB was a separate package. Long story short, it is not supported. That said if you just run the same code and replace tensorboard_logger with tensorboard, you should see all scalars in the UI

background:
ClearML logs TB events as they are created in real-time, TB_logger is not TB, it creates events and dumps them directly into a TB equivalent event file
