How to disable progress bar in Pytorch Lightning

Question

I have a lot of issues withe the tqdm progress bar in Pytorch Lightning:

• when I run trainings in a terminal, the progress bars overwrite themselves. At the end of an training epoch, a validation progress bar is printed under the training bar, but when that ends, the progress bar from the next training epoch is printed over the one from the previous epoch. hence it's not possible to see the losses from previous epochs.

INFO:root:  Name    Type Params
0   l1  Linear    7 K
Epoch 2:  56%|████████████▊          | 2093/3750 [00:05<00:03, 525.47batch/s, batch_nb=1874, loss=0.714, training_loss=0.4, v_nb=51]

• the progress bars wobbles from left to right, caused by the changing in number of digits behind the decimal point of some losses.
• when running in Pycharm, the validation progress bar is not printed, but in stead,

I would like to know if these issues can be solved or else how can I disable the progress bar and instead, just print some log details on the screen.

Answer 1

F.Y.I. show_progress_bar=False deprecated since version 0.7.2, but you can use progress_bar_refresh_rate=0

---

update:

progress_bar_refresh_rate has been deprecated in v1.5 and will be removed in v1.7. To disable the progress bar, set enable_progress_bar to false

progress_bar_refresh_rate: How often to refresh progress bar (in steps). Value ``0`` disables progress bar.
    Ignored when a custom progress bar is passed to :paramref:`~Trainer.callbacks`. Default: None, means
    a suitable value will be chosen based on the environment (terminal, Google COLAB, etc.).

    .. deprecated:: v1.5
        ``progress_bar_refresh_rate`` has been deprecated in v1.5 and will be removed in v1.7.
        Please pass :class:`~pytorch_lightning.callbacks.progress.TQDMProgressBar` with ``refresh_rate``
        directly to the Trainer's ``callbacks`` argument instead. To disable the progress bar,
        pass ``enable_progress_bar = False`` to the Trainer.

enable_progress_bar: Whether to enable to progress bar by default.
