ehsanmok commented on issue #14875: MXNet to ONNX export bug URL: https://github.com/apache/incubator-mxnet/issues/14875#issuecomment-492800991 @vandanavk here is an MVE ```python from os import path as osp import numpy as np import mxnet as mx from mxnet.contrib import onnx as onnx_mxnet from mxnet import gluon from gluoncv import model_zoo, data, utils OUTPUT = "./output" DATA = "./data/cat.png" SIZE = 320 MODEL = "yolo3_mobilenet1.0_coco" INPUT_SHAPE = (1, 3, SIZE, SIZE) net = model_zoo.get_model(MODEL, pretrained=True) net.hybridize() # pass an img to trigger init after hybridize x, _ = data.transforms.presets.yolo.load_test(DATA, short=SIZE) _, _ = net(x) net.export(osp.join(OUTPUT, MODEL)) sym = osp.join(OUTPUT, MODEL + "-symbol.json") params = osp.join(OUTPUT, MODEL + "-0000.params") onnx_file = osp.join(OUTPUT, MODEL + ".onnx") converted_model_path = onnx_mxnet.export_model(sym, params, [INPUT_SHAPE], np.float32, onnx_file, verbose=True) ```
