openvino.runtime.opset9.ctc_greedy_decoder_seq_len(data: Node | int | float | ndarray, sequence_length: Node | int | float | ndarray, blank_index: Node | int | float | ndarray | None = None, merge_repeated: bool = True, classes_index_type: str = 'i32', sequence_length_type: str = 'i32', name: str | None = None) → Node#

Return a node which performs CTCGreedyDecoderSeqLen.

Parameters:

  • data – The input 3D tensor. Shape: [batch_size, seq_length, num_classes]

  • sequence_length – Input 1D tensor with sequence length. Shape: [batch_size]

  • blank_index – Scalar or 1D tensor with specifies the class index to use for the blank class. Optional parameter. Default value is num_classes-1.

Returns:

The new node which performs CTCGreedyDecoderSeqLen.
