bug(tqdm): creating multiple rows after 70%
🐛 Bug
When I run a training loop, every epoch it would do tqdm well until roughly 70%, and then create more rows until finished:

Expected behavior
No new tqdm rows

Additional context
Running this using PyCharm, not directly on the terminal.
This seems to happen directly in the terminal as well, in tmux
