The document is incorrectly converted.

This may be happening in other places as well.

In the following function's argument, the subs is passed as a tuple. And it is correct.

matplotlib/lib/matplotlib/ticker.py

Line 2272 in b71ee62

def __init__(self, base=10.0, subs=(1.0,), numdecs=4, numticks=None):

But if it is documented, the argument subs is passed as a scalar. This is wrong.

class matplotlib.ticker.LogLocator(base=10.0, subs=1.0, numdecs=4, numticks=None)[source]

Thanks for the report!

This is a sphinx issue. I've reported this upstream in sphinx-doc/sphinx#9364.

I'm closing this because we cannot do anything about it.
