[TVM Discuss] [Questions] Lambda op for Keras


Operator Lambda is not supported for frontend Keras. Have plan for support?

@zchuang11 Supporting those operators looks difficult in near future.  I think trying other models is better for now, unfortunately.

@kazum Thanks for your reply in patience. 

I have converted the keras model '*.h5' to tensoflow model(*.pb). There are four ops are not supported using 'tensorflow frontend using relay.frontend.from_tensorflow', as:
```Python
otImplementedError: The following operators are not implemented: {'DenseToDenseSetOperation', 'NonMaxSuppressionV3', 'SparseToDense', 'Unique'}
```
Could you help me to support it?  Thanks a lot!

The Lambda layer can contain anything, so I think it's difficult to support.

If your keras model contains Lambda, I'd suggest converting it to a tensorflow model and use the tensorflow frontend instead.  c.f. https://github.com/amir-abdi/keras_to_tensorflow/
