defrna_loss(log_probs,# type: torch.FloatTensorlabels,# type: torch.IntTensorframes_lengths,# type: torch.IntTensorlabels_lengths,# type: torch.IntTensoraverage_frames=False,# type: boolreduction=None,# type: Optional[AnyStr]blank=0,# type: int):"""The CUDA-Warp Recurrent Neural Aligner loss. Args: log_probs (torch.Tensor): Input tensor (float) with shape (T, N, U, V) where T is the maximum number of input frames, N is the minibatch size, U is the maximum number of output labels and V is the vocabulary of labels (including the blank). labels (torch.IntTensor): Tensor with shape (N, U-1) representing the reference labels for all samples in the minibatch. frames_lengths (torch.IntTensor): Tensor with shape (N,) representing the number of frames for each sample in the minibatch. labels_lengths (torch.IntTensor): Tensor with shape (N,) representing the length of the transcription for each sample in the minibatch. average_frames (bool, optional): Specifies whether the loss of each sample should be divided by its number of frames. Default: ``False''. reduction (string, optional): Specifies the type of reduction. Default: None. blank (int, optional): label used to represent the blank symbol. Default: 0. """# type: (...) -> torch.Tensor
