Class Documentation

class MultiheadAttentionImpl : public torch::nn::Cloneable<MultiheadAttentionImpl>

Applies the MultiheadAttention function element-wise.

See https://pytorch.org/docs/main/nn.html#torch.nn.MultiheadAttention to learn about the exact behavior of this module.

See the documentation for torch::nn::MultiheadAttentionOptions class to learn what constructor arguments are supported for this module.

Example:

MultiheadAttention model(MultiheadAttentionOptions(20, 10).bias(false));

Public Functions

inline MultiheadAttentionImpl(int64_t embed_dim, int64_t num_heads)

explicit MultiheadAttentionImpl(const MultiheadAttentionOptions &options_)

std::tuple<Tensor, Tensor> forward(const Tensor &query, const Tensor &key, const Tensor &value, const Tensor &key_padding_mask = {}, bool need_weights = true, const Tensor &attn_mask = {}, bool average_attn_weights = true)

virtual void reset() override

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

Protected Functions

inline virtual bool _forward_has_default_args() override

The following three functions allow a module with default arguments in its forward method to be used in a Sequential module.

You should NEVER override these functions manually. Instead, you should use the FORWARD_HAS_DEFAULT_ARGS macro.

inline virtual unsigned int _forward_num_required_args() override

inline std::vector<torch::nn::AnyValue> _forward_populate_default_args(std::vector<torch::nn::AnyValue> &&arguments) override
