Segmentation fault during MNN Model export

[MarcoMultichannel]

I get a "segmentation fault" when I try to convert the ONNX model in MNN model:

MNNConvert -f ONNX --modelFile voxceleb_resnet34.onnx --MNNModel model.mnn --bizCode MNN

Segmentation fault

It happens both with and without --saveStaticModel.
The model used is the pretrained model available, but I tried exporting a model using the updated export_onnx.py script and the problem persists.
The MNN version and flags are the same as defined in the CMakeFiles.txt.

@cdliang11 Pls follow this.

mnn version:

MNN    2.8.3

Try exporting the model using export_mnn.py.

[MarcoMultichannel]

Still segmentation fault.
If I try to export the model using export_mnn.py it doesn't find the executable "MNNConvert", since it calls MNNConvert using os.system.

How can I compile MNN to recreate the same environment of the test? I'm starting to think that I'm not compiling it properly.

try: pip install MNN

I managed to convert the model without a segmentation fault happening.
I installed mnn with pip install MNN as you said and then instead of using MMNConvert I executed the python version:

python -m mnnconvert -f ONNX --modelFile model.onnx --MNNModel model.mnn --bizCode MNN
