JAX has some limitations and gotchas on what it can compute the gradient of and can require workarounds, but most of them feel quite “natural” (e.g. that PRNG requires explicit state) and I haven’t hit those in practice with my toy example.

We create two tensors a and b with requires_grad=True. This signals to autograd that every operation on them should be tracked. import torch a = torch.tensor( [2., 3.], requires_grad=True) b = torch.tensor( [6., 4.], requires_grad=True) We create another tensor Q from a and b.
WebTo check the first possibility (we touch a contour line of f ), notice that since the gradient of a function is perpendicular to the contour lines, the tangents to the contour lines of f and g are parallel if and only if the gradients of f and g are parallel. Thus we want points (x, y) where g(x, y) = c and for some where WebThis file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.
