I’m doing something wrong already in the djmodel function (the 1st graded function); the test gives me:
AttributeError: The layer “lstm” has multiple inbound nodes, with different output shapes. Hence the notion of “output shape” is ill-defined for the layer. Use get_output_shape_at(node_index)
instead.
If it’s OK to post my code here, please let me know. I must be missing something basic, but I’m just stuck.
