Some package, such as DVC allow you to install extra dependencies to use additional features: to install a single extra dependency, whether by command line or in a requirements.txt, you simply use brackets:
# requirements.txt dvc[s3]
pip install -r requirements.txt
But how can you install multiple extra dependencies of a single package ? There is of course the possibility to create multiple lines
# requirements.txt dvc[s3] dvc[gs]
However this seems a bit unelegant to me, as if I want to specify a version, I have to make sure that both line use the same.
Would it be possible to do that on a single line ?
I have found no reference to a specific syntax, and have already tried dvc[s3][gs] and dvc[gs, s3], to no avail.

Of course, I found the solution right after posting, you just have to remove the space after the comma:
# requirements.txt dvc[s3,gs]
pip install -r requirements.txt
Works fine
