🐛 Bug description

Currently, the CI is broken due to recent changes of tqdm v4.49.0 :

• https://travis-ci.org/github/pytorch/ignite/jobs/726808846#L4137

Idea is to fix tqdm's version to v4.48.0 for all CI here:

@vfdev-5 Hi, I'd like to give this a try for my first Hacktoberfest issue. Can you assign this to me and I will give it ago

[vfdev-5]

@benji011 sure, thanks !

PS: a short note

for my first Hacktoberfest issue

As we are still in September, PRs opened now won't count for Hactoberfest PRs. https://github.com/pytorch/ignite/issues/1257#issuecomment-688461008
But this counts a lot for the projects you are contributing !

[vfdev-5]

@benji011 could you please send a PR in coming days (monday, tuesday) as fixing CI is important ?
If you need any guidelines or you have any questions, please ask.

@vfdev-5 I thought this was a Hacktoberfest issue, Is it still ok to submit before October 1st?

[vfdev-5]

@benji011 well, it is a HF issue. As organizers stated in their docs:

September is Preptember – a full month for maintainers to groom your repositories and for contributors to learn about making quality pull requests.

So, yes, it is OK to submit before October 1st to "learn about making quality pull requests".
