Description

There is a bug, maybe this one - https://github.com/tqdm/tqdm/issues/485 which prevents from using tqdm_notebook in JupyterHub, Lab or Notebook. At the moment the output is blank.

The easiest way seemed to simply use tqdm, I don't want to implement another progress bar. Screenshot 2019-03-13 at 12 39 57
