Description

Hello!

Is there a tutorial on how to inspect gradient/hessian calculation when using diffrax?

I am trying to calculate gradients and hessians, but the returned values are always nans, and I do not know where to start "debugging".

Research direction

Start by reproducing the reported NaN gradient and Hessian calculation in diffrax and inspect the autodifferentiation path. The issue names no file, test, or example, so a useful contribution would first need a minimal reproduction and a documented way to inspect the calculation.
