Progress bar does not display in jupyter lab

[ivaniadg]

Hi!

I'm running the library on my computer (ubuntu 18.04.5) on a jupyter lab notebook.

I'm using the model IFALsConjugateGradient and when training I set the option progress=True but it does not display the progress bar.

obj = pyreclab.IFAlsConjugateGradient( factors = 50,
                                           dataset = TRAIN_PATH.as_posix(),
                                           dlmchar = b',',
                                           header = True,
                                           usercol = 0,
                                           itemcol = 1,
                                           observationcol = 3 )
obj.train(progress=True)

Is there an additional library I should install?

These are the python libraries I have installed.

Hi @indonoso, thanks for your report ! ...

you don't need an additional library to fix it. There's a known issue related to standard output writing and jupyter notebook.

https://stackoverflow.com/questions/46068321/jupyter-notebook-does-not-show-c-output-cout

I'm going to figure out if there is a work around to solve this problem.
