[GitHub] [incubator-mxnet] becauseofAI opened a new issue #17942: error when
slice_axis exporting to onnx
becauseofAI opened a new issue #17942: error when slice_axis exporting to onnx
URL: https://github.com/apache/incubator-mxnet/issues/17942
## Description
An error occurred when exporting the ```slice_axis()``` operation of mxnet to onnx.
### Related code
```python
branch1_conv3 = mxnet.symbol.Convolution(data=branch1_relu2,
kernel=(1, 1),
stride=(1, 1),
pad=(0, 0),
num_filter=2,
name=prefix_name_branch1)
predicts = mxnet.symbol.softmax(data=branch1_conv3, axis=1)
predict = mxnet.symbol.slice_axis(predicts, axis=1, begin=0, end=1)
```
The corresponding json code block is as follows:
```json
{
"op": "Convolution",
"name": "branch1_conv3",
"attrs": {
"kernel": "(1, 1)",
"num_filter": "2",
"pad": "(0, 0)",
"stride": "(1, 1)"
},
"inputs": [[45, 0, 0], [46, 0, 0], [47, 0, 0]]
},
{
"op": "softmax",
"name": "softmax0",
"attrs": {"axis": "1"},
"inputs": [[48, 0, 0]]
},
{
"op": "slice_axis",
"name": "slice_axis20",
"attrs": {
"axis": "1",
"begin": "0",
"end": "1"
},
"inputs": [[49, 0, 0]]
}
```
### Error Message

```
### Environment
mxnet==1.5.0/1.5.1/1.6.0
onnx>=1.4.0 # the above error occurred
onnx==1.1.1/1.3.0 # exported successfully
So if I want to use onnx==1.6.0 to export successfully, what can I do for this error?

Hi @becauseofAI,
I also experienced issues with the slice operator export and created a PR about this:
https://github.com/apache/incubator-mxnet/pull/17827
Unfortunately, MXNet lacks support for ONNX versions > 1.3.0 at the moment:
https://github.com/apache/incubator-mxnet/issues/14589
I think MXNet should aim to support the latest ONNX versions.
Otherwise it won't benefit from all the bug fixes which were implemented in newer ONNX version.
