Issue with customized object

[Debottam]

Dear Developers, In https://github.com/Debottam/onnxExamples/blob/master/keras2onnx_Issue.ipynb I am getting an error from

def streched_tanh(x):
    beta = 5
    return beta*K.tanh(x)

It will be great if you guys have a look at https://github.com/Debottam/onnxExamples/blob/master/keras2onnx_Issue.ipynb and suggest.

Thanks, Debottam
