bfgoldstein opened a new issue #19066: URL: https://github.com/apache/incubator-mxnet/issues/19066
## Description I was trying to load the Arcface model downloaded from [ONNX model zoo](https://github.com/onnx/models/tree/master/vision/body_analysis/arcface), but a "NotImplementedError: Operator Sub not implemented." exception was raised. It seems that this model had some problems before, but it was fixed [here](https://github.com/apache/incubator-mxnet/pull/17711). However, there is a [commit](https://github.com/apache/incubator-mxnet/commit/fb73de7582de4e622299a4ad045e25f771568193#diff-7b131e64cf22cff749bd44de10b64b7f) made on June 10 that removes support for some ONNX Operators, like add, subtract, multiply, and divide. ### Error Message ``` [12:03:05] /home/bruno/mxnet/mxnet/src/storage/storage.cc:198: Using Pooled (Naive) StorageManager for CPU Traceback (most recent call last): File "error_reproduce.py", line 5, in <module> sym, arg_params, aux_params = import_model(model) File "/home/bruno/mxnet/mxnet/python/mxnet/contrib/onnx/onnx2mx/import_model.py", line 59, in import_model sym, arg_params, aux_params = graph.from_onnx(model_proto.graph) File "/home/bruno/mxnet/mxnet/python/mxnet/contrib/onnx/onnx2mx/import_onnx.py", line 115, in from_onnx mxnet_sym = self._convert_operator(node_name, op_name, onnx_attr, inputs) File "/home/bruno/mxnet/mxnet/python/mxnet/contrib/onnx/onnx2mx/import_onnx.py", line 63, in _convert_operator raise NotImplementedError("Operator {} not implemented.".format(op_name)) NotImplementedError: Operator Sub not implemented. ``` ## To Reproduce - Download the model from [ONNX model zoo](https://github.com/onnx/models/tree/master/vision/body_analysis/arcface/model). File **arcfaceresnet100-8.onnx** (git lfs); - Then run the python script below ### Minimal python script: ``` import sys from mxnet.contrib.onnx.onnx2mx.import_model import import_model model = sys.argv[1] sym, arg_params, aux_params = import_model(model) ``` ## Environment - OS: CentOS 8.2 - Python: 3.7.7 - ONNX: 1.7.0 - MXNET: master (built from source) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
