tf.keras.backend.ctc_batch_cost(
    y_true, y_pred, input_length, label_length
)

Arguments
`y_true`	tensor `(samples, max_string_length)` containing the truth labels.
`y_pred`	tensor `(samples, time_steps, num_categories)` containing the prediction, or output of the softmax.
`input_length`	tensor `(samples, 1)` containing the sequence length for each batch item in `y_pred`.
`label_length`	tensor `(samples, 1)` containing the sequence length for each batch item in `y_true`.

Returns
Tensor with shape (samples,1) containing the CTC loss of each element.
