tqdm_notebook doesn't work on Google Colab platform.

[IAmSuyogJadhav]

While working on notebooks in the Google's cloud computing environment (Google Collaboratory), the tqdm.tqdm_notebook seems to be not working.

It raises error saying "NameError: name "IntProgress" is not defined"

How to reproduce:

1. Create a new notebook on colab.research.google.com (given you have a google account. The platform is free, however)
2. Try to use tqdm_notebook.

@IAmSuyogJadhav tqdm_notebook requires the installation and compatibility of ipywidgets (https://github.com/jupyter-widgets/ipywidgets), which Google Collaboratory does not have (googlecolab/colabtools#60).

Since this is an upstream problem, there is nothing to do on tqdm. You may wait some days, perhaps Google will fix the compatibility of ipywidgets.

An alternative way is to use tqdm instead of tqdm_notebook, like this:

Although it is imperfect, it does work.

@casperdcl I suggest close this issue until the upstream compatibility problem is fixed.

thanks @chengs @IAmSuyogJadhav

Oh I see! Thanks for helping out ! @chengs

@IAmSuyogJadhav can you try this #640 and give me some feedback?

[chengs]

I reopen this because I am trying to solve it.
#640

[IAmSuyogJadhav]

Tried #640 on Google Colab.
Looks to be working fine. Only a minor compatibility issue I see here, though.

@chengs is this still an issue? maybe we can close this issue?

[IAmSuyogJadhav]

I have been using tqdm in jupyter notebooks without any trouble for quite a while now. I can confirm this is no longer an issue. This can be closed, from my side at least.

I have ran into this problem recently and it uses a lot of ram. See this issue on colab github:

here is how "from tqdm.auto import tqdm" looks like on google colab.
