[harsh8398]

Completes #1427

Description:

• Added example notebook showing usage of HandlerTimeProfiler
• Added notebook entry in README as well

Just want to add that, while modifying README I noticed that pre-commit was suggesting lot of whitespace related changes in the README.

@harsh8398 thanks for the PR ! I was wondering if you also see the cell with printed results like below:

About the precommit, I think it should be related to #1468. Could you please dump the diff once with the precommit, maybe it is OK and just accept them ?

@vfdev-5 Yes, I am seeing the same output. I was able to fix that spill by using the trick mentioned here. The output looks as follows now:

Sorry, I didn't get you. What are you suggesting? Do you want me to add those precommit changes in this PR?

@sdesrozis could you please review the PR and merge if it is OK

@harsh8398 Maybe we should add a line to install Pytorch-ignite in notebook

!pip install --upgrade --pre pytorch-ignite

What do you think ?

There is a warning from ignite/contrib/handlers/time_profilers.py:587

UserWarning: To copy construct from a tensor, it is recommended to use sourceTensor.clone().detach() or sourceTensor.clone().detach().requires_grad_(True), rather than torch.tensor(sourceTensor).
  data = torch.tensor(data, dtype=torch.float32)

Could we remove it ?

EDIT : mentioned points are not mandatory and should be addressed in PRs (others notebooks don't have install command and warning is not directly related to this work).

[harsh8398]

@sdesrozis I have added the suggested cell at the top. Also, I've raised a PR(#1487) for the change required to remove the warning.

@harsh8398 I think you didn't commit the good installation command line in notebook. Could you check and fix please ?

[harsh8398]

@sdesrozis Sorry for that, Its fixed now.

@harsh8398 Thank you LGTM !
