[ONNX] Missing and outdated operators

Development
#1

Hello everyone,

I’m trying to compile the official ONNX SSD model, but I got missing operators: NonMaxSuppression and TopK (even though they exist in Relay).

I tried to add them in tvm/python/tvm/relay/frontend/onnx.py, but now I get an error on the Slice operation, coming from the change in ONNX operators version (current operators vs outdated operators).

I can’t resolve it, and it is probable that other errors will arise due to the version change.
How can I help you? Providing a list of outdated operators? I’m not 100% sure about my fixes for NonMaxSuppression and TopK.

Thanks!

We meet the same situation.
Are you going to add V10 Slice OP? Or try to modify V10 Slice OP to V1?
