[Solved]MXNet to ONNX export bug with "out_shape" when using Crop

[AnaRhisT94]

Hi,
I know Crop is deprecated, and probably this why "out_shape" key isn't available. Is there a future fix for this?
The current available workaround for this is just specifying the height and width manually for the crop, but it's not a long-term fix, if I will be using other width/height, and so on.

Just used Crop with num_args = 1 and sliced the h_w accordingly in the .json file (Directly).
Also I suggest using ONNX==1.2.2 instead of 1.2.1, which has less op support for mxnet to onnx export functionality.

How to sliced the h_w accordingly in the .json file? Have you changed _op_translations.py? Thank U~

I didn't understand how to fix it, could you elaborate more
