Public Functions

PoissonNLLLossImpl(const PoissonNLLLossOptions &options_ = {})
void reset() override

reset() must perform initialization of all members with reference semantics, most importantly parameters, buffers and submodules.

void pretty_print(std::ostream &stream) const override

Pretty prints the PoissonNLLLoss module into the given stream.

Tensor forward(const Tensor &log_input, const Tensor &targets)
