"No Op registered" error - IR Version Issue?

[avatarrokuaskingquestions]

Firstly thanks for making this tool! I was trying to use it on the palm model here and Python 3.10.11, I get the following error:

openvino2onnx --model-bin palm_detection_FP32.bin --fp32 palm_detection_FP32.xml
[E] Failed to build graph to onnx model v10 opset=17
Traceback (most recent call last):

==> Context: Bad node spec for node. Name: conv2d_prelu/Neg_1/mul_/Negate OpType: Negative

Tried the other opsets and got the same error. Since the model is 'version=10' I tried installing openvino==2022.3.0 but that didn't change anything. If it was an IR Version issue would I need to do anything else on my end? Or do you think it's something else?

This repo doesn't cover all openvino opsets, and the op Negative is missing a converting rule here, if possible, you could add a rule for Negative, thanks!

Please try v1.0 again
