I’m writing a custom op for TorchScript, and the c++ function is like
at::Tensor myforward(const at::Tensor& input0, // input
const at::Tensor& input1, // weight
const optional<Tensor>& input2, // bias
because the bias may be None in python, and how to convert the optional to Tensor?
I tried input2.value_or(Tensor{})
but couldn’t be compiled.
