_The documentation is not available anymore as the PR was closed or merged._<|||||>Hi @AdiaWu and @JuheonChu, thank you for the contribution 🚀 The doctest is confirmed to pass with this change, but there are 2 lines that should not be deleted in this PR. Once that part is reverted, we are ready to merge 💯 <|||||>Hi @ydshieh Thank you very much for your advice, we will work on it now! <|||||>Hi, @AdiaWu, 

[Update]

You created a new file `src/transformers/utils/documentation_tests.txt`. This should be removed, and we only need to add 1 line in  the existing file `utils/documentation_tests.txt`.

~~I am not sure if something changed since yesterday, but currently, the file `documentation_tests.txt` is completely  modified, in particular in [this commit](https://github.com/AdiaWu/transformers/commit/657de28e023ff305fde3356e187b96c29bca1f07)~~

~~Why that file is re-created in that commit? Before we can merge this PR, you will have to make that file clean - there should be only 1 line change instead of all file being changed.~~



<|||||>I am sorry for the trouble. However, I only added line 172 and line 173 as you instructed yesterday. May I ask you what is the one line that you want me to revise? We will try to work on it again. <|||||>Dear @ydshieh 
and from this site: https://github.com/huggingface/transformers/pull/21446/commits/82d5a6216e3c4596f2213dbee440f12bdaa35fcb. You can check that I only added two lines to the document... Not sure if somewhere went wrong.. 
Agian, sorry for the trouble. <|||||>One commit before, there is unusual changes:

https://github.com/huggingface/transformers/pull/21446/commits/657de28e023ff305fde3356e187b96c29bca1f07<|||||>@ydshieh Thank you! We will remove the file right away.<|||||>@ydshieh Hello, I just wanted to double check. So, what @JuheonChu and I should do is deleting "`src/transformers/utils/documentation_tests.txt`" file. Are we understanding correctly?<|||||>> @ydshieh Hello, I just wanted to double check. So, what @JuheonChu and I should do is deleting "`src/transformers/utils/documentation_tests.txt`" file. Are we understanding correctly?

Yes<|||||>Hi @AdiaWu If you check on the changed file page

https://github.com/huggingface/transformers/pull/21446/files

It shows the file `utils/documentation_tests.txt` is not there (or points to `src/transformers/utils/documentation_tests.txt`.

I suggest you verify the file locally, make sure `utils/documentation_tests.txt` exist, not a symbolic link to other files, and with the expected one-line change you want to add for this PR 🙏.<|||||>@ydshieh Is the file `utils/documentation_tests.txt` already in our commits? <|||||>Dear @ydshieh , 
Since the file "utils/documentation_tests.txt" is missing. @JuheonChu and I just updated the "utils/documentation_tests.txt". There should be no problem with the file now. Please check it whenever you are available and see if there are still some errors this time. <|||||>Hi @AdiaWu 

- The file `src/transformers/utils/documentation_tests.txt` should not be added.
- The file `utils/documentation_tests.txt` should not be deleted.

It seems at some point of your commits, you have done something to these  2 files.

What needs to be done is:

- remove the newly added file `src/transformers/utils/documentation_tests.txt`
- make sure  `utils/documentation_tests.txt` exist, and is not a symbolic link to any other file
- make sure `utils/documentation_tests.txt` is updated with one line `src/transformers/models/timesformer/configuration_timesformer.py`

I hope this is clear and we can merge the PR once everything is fine, thank you.
I can help to resolve this issue if necessary, please let me know :-) <|||||>Dear @ydshieh , I am sorry for misunderstanding your instructions, we have now deleted the "src/transformers/utils/documentation_tests.txt" file, and the "utils/documentation_tests.txt" is currently in the path with only one line added. I hope this time this PR should be all good and ready to be merged. Thank you very much! <|||||>> Dear @ydshieh , I am sorry for misunderstanding your instructions, we have now deleted the "src/transformers/utils/documentation_tests.txt" file, and the "utils/documentation_tests.txt" is currently in the path with only one line added.
