[BUG] Running `make html-noplot` yields errors.

Add Link

I ran the following command about 10 hours ago, around 12:20:00 utc and it gave me errors. (I am being specific about the time, because I was unable to find a release that I could point to).
git clone --depth 1 https://github.com/pytorch/tutorials.git

make: *** [html-noplot] Error 2

What did you expect to happen?

As stated in the README.md file, I expected a basic html version of the tutorial to be built at _build/html

Steps to Reproduce the error

1. Run the git command below
   git clone --depth 1 https://github.com/pytorch/tutorials.git

2. Run pip install -r .ci/docker/requirements.txt. I am aware the instruction was to pip install -r requirements.txt. But
   I keep encountering the errors below, so I improvised.

ERROR: Invalid requirement: '.ci/docker/requirements.txt': Expected package name at the start of dependency specifier
    .ci/docker/requirements.txt
    ^ (from line 1 of requirements.txt)

3. Run make html-noplot. For this one, I gnuWin32 make. This is what is available on Windows.

   I noticed that this error is similar to that found when I run re.compile('\c'). I am familiar with this scenario and so I looked further and traced the error to the code here. I was able to move on from this error by modifying my local version of the code to
   SPHINX_SHOULD_RUN = "|".join(get_files_for_sphinx()).replace('\\', '\\\\')
   I want to note that I do not feel confident in that action because I notice that code was last modified 2 years ago, unless I have a wrong interpretation of what the "2 years ago" that I see around there means. It was last modified 2 years ago! That means that working tutorials have been built with that piece of code. This makes me feel very strongly that something is wrong with my setup. But I resisted raising any issues because I considered that it might not be worth it to distract the attention of our dear conscientious developers whose efforts to maintain this codebase does not go unnoticed.

4. Run make html-noplot once more.
   The error above appears. I look at the error and I see multiprocessing.py there. I do not know how to do anything with code that runs on more than one thread or process. I would appreciate knowing what I have done wrong in my environment because surely the code in this repository works as it has been tested as required.

Describe your environment

Environment

• Python 3.10.5
• pip 25.1.1
• All commands were run in the top directory of the cloned repository
• All pip-installing was done in a fresh virtual environment created using venv and located in the top directory of the cloned repository. The command used for that was python -m venv doc-env.
• GPU (not cuda): Intel Iris Xe (Not sure this is relevant)

Start with the make html-noplot entry point and .jenkins/get_sphinx_filenames.py, then reproduce the documented build in the stated Windows, Python 3.10, and virtualenv environment. Check the requirements installation and the reported Sphinx gallery and multiprocessing errors; done means the basic HTML tutorial builds at _build/html without those errors.
