WebOct 14, 2024 · For me, integration with vmap is less important. However, functorch's explicit interface is much nicer to generally integrate with other autodiff systems like those in say Julia.I use it in PyCallChainRules.jl so that users can integrate their differentiable pytorch functions in Julia. WebIn your example ctx is the parameter and technically the property of self where you can put many tensors. Note: When you define torch.nn.Module define just the forward () function, that is not @staticmethod. When you define new autograd function you define both the …
