hi Thank you for your work, when I run "./libtorch-yolov5 /data_1/train_project/OBJ_Detection/yolov5-forward/module/torchscript.pt /data_1/train_project/OBJ_Detection/yolov5-forward/img/000240_01046820200606110918_0035_670_3cls.jpg -gpu". The following error occurred

how to solve this problem

Hi @name333 , did you follow the instruction here https://github.com/yasenh/libtorch-yolov5#torchscript-model-export? I can duplicate your error msg if I use the original "export.py" from yolov5 repo.

yasenh commented 3 years ago

line 28

model.model[-1].export = False
The modification above is required for both cpu & gpu, and the other 2 lines of gpu map location update is optional.

I will revise the instructions little bit later on.

首先非常感谢ultralytics大神，我们团队把yolov5模型重构了，并且复现了和原仓库同样的水平，优势是可以端到端转换移动端模型，如果你有时间有需要，请移步yolov5，期待各位的驾临。
