[GitHub] [incubator-mxnet] flexwend opened a new issue #19803: Failed to load mobilenetv2-7 of ONNX model zoo with MXNet
flexwend opened a new issue #19803:
URL: https://github.com/apache/incubator-mxnet/issues/19803
## Description
While trying to load the mobilenetv2-7 (onnx 1.2.1, opset 7, [Mobilenet in ONNX model zoo](https://github.com/onnx/models/tree/master/vision/classification/mobilenet)) with mxnet the following error occures. I am using:
- onnx 1.7.0
- mxnet 1.7.0
- python 3.8.5
Other examples work fine like:
- googlenet-3.onnx
- googlenet-9.onnx
- resnet18-v2-7.onnx
- tinyyolov2-8.onnx
- vgg16-7.onnx
Some are failing too with similar errors:
- mtiny-yolov3-11.onnx
- yolov2-coco-9.onnx
- yolov3-10.onnx
- yolov4.onnx
When will the changes to [contrib/onnx](https://github.com/apache/incubator-mxnet/tree/master/python/mxnet/contrib/onnx) be introduce into a stable version?

## To Reproduce
```
import onnx
import mxnet.contrib.onnx as onnx_mxnet
model_path = 'mobilenetv2-7.onnx'
onnx_model = onnx.load(model_path)
onnx.checker.check_model(onnx_model)
print("checked")
sym, arg, aux = onnx_mxnet.import_model(model_path)
```
## What have you tried to solve it?
1. other onnx version (1.8, 1.6, problems installing older versions)

Thanks for the reply @Zha0q1. The use case is to load and fine-tune an onnx model followed by inference, similar to this [tutorial](https://mxnet.apache.org/versions/1.7.0/api/python/docs/tutorials/packages/onnx/fine_tuning_gluon.html)

Hi @flexwend, yeah the onnx support has been a little behind but we are actively working on improving it. We are trying to prioritize mx2onnx at the moment. We do have many models trained in mxnet that you can export to onnx fine (https://cv.gluon.ai/model_zoo/index.html). May I ask your use case after import? Are you trying to train or inference? Thanks!
