SimpleSeq2Seq

[natank1]

When I train SimpleSeq2Seq I get the error :

optional_input_placeholder = _to_list(_OptionalInputPlaceHolder().inbound_nodes[0].output_tensors)[0]
AttributeError: '_OptionalInputPlaceHolder' object has no attribute 'inbound_nodes'

from recurrentshop . I am using Python 2.7.13

Thanks
