Detailed Documentation

Returns embeddings for given indices.



Constructs a EmbeddingBagOffsetsBase operation.

    const Output<Node>& emb_table,
    const Output<Node>& indices,
    const Output<Node>& offsets,
    const Output<Node>& default_index,
    const Output<Node>& per_sample_weights

Constructs a EmbeddingBagOffsetsBase operation.

EmbeddingBagOffsetsBase constructs an output tensor by replacing every index in a given input tensor with a row (from the weights matrix) at that index



tensor containing the embedding lookup table of the module of shape [num_emb, emb_dim1, emb_dim2, …] and of type T


of shape [num_indices] and of type T_IND. Required


tensor of shape [batch] and of type T_IND containing the starting index positions of each “bag” in indices. Required.


tensor of the same shape as indices and of type T. Each value in this tensor are multiplied with each value pooled from embedding table for each index. Optional.


scalar of type T_IND containing default index in embedding table to fill empty “bags”. If not provided empty “bags” are filled with zeros. Optional.


virtual const NodeTypeInfo& get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.

virtual void validate_and_infer_types()

Verifies that attributes and inputs are consistent and computes output shapes and element types. Must be implemented by concrete child classes so that it can be run any number of times.

Throws if the node is invalid.
