How can I get exhaust list of functions available to grad_fn for backward() function in Pytorch?

Question

Tensors which can calculate gradient will have grad_fn=AddBackward0 or MulBackward0 or SubBackward0.

Is there any Python command that can list all these "xxxBackward0" methods and their respective forward and backward formulas?

Answer 1

I don't know about a singular python command, but you can check out the methods for torch.Tensor.

Basically all tensor operations that aren't "hard" (ie like argsort, logical operators) have a backward method implemented.
