AttributeError: The layer "concatenate" has multiple inbound nodes

AttributeError: The layer “concatenate” 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.

I reloaded the notebook but it didn’t work this time can someone help me fix it !
