WebJan 11, 2024 · Thank you for your reply. This makes sense to me. But I think the ‘dy/dz’ in the comment # dy/dz calculated outside of autograd should be ‘dz/dy’. My understanding of your example is that you let the MXNet do the autograd on dy/dx which should be 2, and told autograd you already have the dz/dy part manually which is [10, 1., .1, .01].Then … WebTo begin, import the np and npx module and update MXNet to run in NumPy-like mode.
