yolov3-ocr.cfg does not have down_stride

[chenscottus]

Hi, I tried to transfer yolo3-spp pt file to onnx, and here is the error:

Traceback (most recent call last): File "Libtorch_yolo_to_onnx.py", line 779, in main() File "Libtorch_yolo_to_onnx.py", line 771, in main model_def = builder.build_onnx_graph( File "Libtorch_yolo_to_onnx.py", line 353, in build_onnx_graph major_node_specs = self._make_onnx_node(layer_name, layer_dict) File "Libtorch_yolo_to_onnx.py", line 426, in _make_onnx_node node_creators[layer_type](layer_name, layer_dict) File "Libtorch_yolo_to_onnx.py", line 729, in _make_yolo_node down_stride = int(layer_dict['down_stride']) KeyError: 'down_stride'

many thanks!

The python file - libtorch_onnx_tensorrt_yolo

yolov3 and yolov3-spp are different. yolov3-spp does not have that. In what you provide about Libtorch_yolo_to_onnx.py and yolov3-ocr.cfg also have the same issue.

Using netron, view the network. In your yolo Plugin，add down_stride(down_stride = (input / output_feature)).
