Introduction:
This page tracks the current status and development to support ONNX on Mxnet. We currently support import of ONNX models into Mxnet.
ONNX-MXNET Import Module
We have two repositories for the import module:
- onnx-mxnet repository inside onnx https://github.com/onnx/onnx-mxnet (deprecated)
- A newly created and refactored module inside Mxnet -> contrib. https://github.com/apache/incubator-mxnet/tree/master/python/mxnet/contrib/onnx/_import
Operator Coverage:
This table keeps track of the status of all ONNX operators supported by Mxnet.
ONNX backend test script reports the coverage on the operators and attributes.
