The commit doesn't depend on sphinx. This is a standalone script now.
The requirements file is at tools/net/ynl/requirements.txt not in sphinx

It disapperared because the original patch version was a sphinx module,
thus, pyaml was not at sphinx dependency.

In the commit final form, the script is a standalone script inside
'tools/net/ynl', and PyYAML is already tracked in
`tools/net/ynl/requirements.txt`.

That said, can you try to install `tools/net/ynl/requirements.txt` and
see if you are able to reproduce the problem?
