[Tensorflow][Relay] relay.concatenate requires all tensors have the same ndim;

Troubleshooting
#1

Hi,

I have a model with a concat operator in TF. It has a concatenate operator in which apparently one of the input tensor has a different shape. Then I got the error relay.concatenate requires all tensors have the same ndim;. Is this a limitation of TVM?, What are possible solutions for this issue?

Thanks

@tico did you ever resolve this?

I resolved it by removing the offending concat operator from my model and implementing that part of the model in an alternative way. After checking the model with the concat operator I was not able to identify anything wrong with that operator.
