Ctc input_lengths must be of size batch_size
WebA model containing this layer cannot be trained with a 'batch_size_multiplier'!= 1.0. The input layer DLLayerInput must not be a softmax layer. The softmax calculation is done internally in this layer. WebAug 17, 2016 · We also want the input to have a fixed size so that we can represent a training batch as a single tensor of shape batch size x max length x features. ... (0, batch_size) * max_length and add the individual sequence lengths to it. tf.gather() then performs the actual indexing. Let’s hope the TensorFlow guys can provide proper …
