While using tcn.tcn.TCN() from the new version
I am getting an error :

/usr/local/lib/python3.6/dist-packages/keras/engine/base_layer.py in _collect_previous_mask(input_tensors)
   1439             inbound_layer, node_index, tensor_index = x._keras_history
   1440             node = inbound_layer._inbound_nodes[node_index]
-> 1441             mask = node.output_masks[tensor_index]
   1442             masks.append(mask)
   1443         else:

AttributeError: 'Node' object has no attribute 'output_masks'

@marsln can you use keras 2.2.4? Seems like they introduced some compat breaking changes.
