按照您的教程readme文档的说明，使用yolov5-v6.1 仓库，执行完 
python export.py --weights=yolov5s.pt  --dynamic --simplify --include=onnx --opset 11
命令得到了onnx模型，并将onnx模型放入到 configs 文件夹的同级目录下的 weights 文件夹下的yolov5文件夹中。

接着进入 bin 文件夹，执行 
./object_detection yolov5 /home/tuc/yolov5-6.1/data/images/bus.jpg
命令，就出现了开头的core dump

请问 configs 下的 yolov5.yaml 文件中的 engine_file 字段的trt 文件是需要自己手动生成吗？

[Li-Hongda]

input has static dimensions [1,3,640,640] 报错的原因是ONNX文件为静态shape，可以使用netron检查一下，然后重新生成一下onnx。或者注释掉代码中关于dynamic shape的处理

[xunxuntu]

我用trtexec工具生成了yolov5s.trt，并放在了weights下，然后执行
./object_detection yolov5 /home/tuc/yolov5-6.1/data/images
命令，显示了推理时间，却没有在保存的图片上将检测框画出来。
如下图

[Li-Hongda]

这个位置要确保scale为float，这里我前段时间修改过，你是否用的最新的代码呢？

[xunxuntu]

是的，是最新的代码。昨天才git下来的

[Li-Hongda]

那就已经是float了，我刚刚测试了这两张图应该是没有问题的，因此我认为还是trt转换出了问题，你可以把config中的dynamic设置为0重新生成一下（因为从报错信息来看onnx为静态文件）

[xunxuntu]

我把dynamic设为了0，还是不起作用。
您是怎么得到trt文件的，我是用这个命令得到的：

root@rtx2060:/usr/local/TensorRT-8.4.3.1/bin# ./trtexec --onnx=/home/tuc/yolov5-6.1/weights/yolov5s.onnx --saveEngine=/home/tuc/yolov5-6.1/weights/outfpbest.trt --workspace=2048 --best

# 导出onnx是用这个命令，yolov5版本是6.1
python export.py --weights=yolov5s.pt  --dynamic --simplify --include=onnx --opset 11

会不会和环境有关
我用的是cuda 11.2 , cudnn 8.4.0 , TensorRT-8.4.3.1
rtx2060

[xunxuntu]

那就已经是float了，我刚刚测试了这两张图应该是没有问题的，因此我认为还是trt转换出了问题，你可以把config中的dynamic设置为0重新生成一下（因为从报错信息来看onnx为静态文件）

之前的报错信息在我导出 trt 模型后，放在weights路径下就自动消失了。

[Li-Hongda]

我这个代码是如果weights路径下没有检测到相应的权重，就调用转换onnx转trt函数，之前的报错是发生在转换这一步；你用trt转好之后就不经过这一步了，所以不报错。但是从当时的报错信息能看出来，你所用的onnx是静态图的，所以在转换成trt时应该把dynamic设置为0，我的意思就是重新转换一下（先把weights下的engine删掉）。版本可能也有关吧，这个得查一下相关的更新文件，但应该不是主要原因。

[xunxuntu]

很奇怪，我删除了原先的onnx 和 trt 文件
重新使用export.py导出了onnx，python export.py --weights=weights/yolov5s.pt --include=onnx

然后将configs/yolov5.yaml 下的dynamic设为0

执行 ./object_detection yolov5 /home/tuc/yolov5-6.1/data/images 依旧不起作用。

会不会 是你代码里的后处理的问题呀，能够打印推理的时间，但是不能画框，是不是检测的那部分。

[Li-Hongda]

我暂时也无法定位问题，因为我复现不出来。。

博主，您好，我将我本地的模型和其代码上传到 https://github.com/xunxuntu/check_todo.git 这里了，您有空可以git 下来帮我看看吗 😁😁😁😁😁😁😁😁😁
