How to properly display Pytorch's math notation inside docstring?
When looking at the docstring of Pytorch functions, the math notations are not properly displayed, e.g.: 
https://pytorch.org/docs/stable/_modules/torch/nn/modules/loss.html

.. math::
    \text{loss}(x, class) = weight[class] \left(-x[class] + \log\left(\sum_j \exp(x[j])\right)\right)


Only if I use my IDE to display the documentation, it renders the latex notation properly.

Is there any switch for displaying math on the website?

The docs in source code won't render unless you try some script injection via Greasemonkey or so.
But first have a look at the standard docs where you can find the rendered formula.
