[Regression] ValueError: The name "151" is used 4 times in the model. All layer names should be unique.

With the current version i am not able to export S3FD anymore. Tested with you gist from the split issue in keras2onnx (https://gist.github.com/nerox8664/cbf70c39967b59d29f49afd9f9205a1b) This happens regardless of setting a name_policy or not.

Traceback (most recent call last):

151 is one of the 4 outputs of the split layer. So it seems like this is realted to layers with multiple outputs.

Ok, so it is because in https://github.com/nerox8664/onnx2keras/blob/master/onnx2keras/operation_layers.py#L208 all outputs get the same name. Expect a PR soon(ish)
