Query: Using additional operators and custom operators

[fritzthekid]

Probably, this query is better placed on some user forum - but I did not find any. My goal is to use custom operators, which have better performance on slow hardware. Such operators are supported by many languages.

First I used the operator (TF2) tf.nn.softsign, which seems to be support by onnx operators (Softsign) - but I could not get it working with keras2onnx. Next I tried to extend the available operators by custom operators (which I defined and used with TF2 and therefore have export them), but now success. Python 3.7.9, tensorflow 2.3.1, onnx 1.7.0, keras2onnx 1.7.0
