Segmentation fault (core dumped)

yolov5 v5.0 tensorrt v5.0 when I use the .wts .engine .cfg made by tensorrt, in tensorrt it test good. ①When I put them into deepstream and use deepstream-app -c deepstream_app_config.txt ②When I put them and load libmyplugins.so and use LD_PRELOAD=./libmyplugins.so deepstream-app -c deepstream_app_config.txt Then …… I don't know why……

The file generated by tensorrt can't work for deepstream? But, I see version 5.1 deepstream tutorial can realize, 6.0 series can't? jetson+yolov5+tenssort+deepstream6.0's imformation is too little to learn, pure beginner. o(╥﹏╥)o

It should not work in the latest repo files. Please use the gen_wts_yoloV5.py file to convert the YOLOv5 models.

Hi, I am having a "segmentation fault" error. This error comes only a few times. Rest of the time the pipeline works fine. The error comes when the pipeline loads again for processing when we send it a message.

Ideally after "nvinference-engine> [UID 2]: Load new model:test_classifier_config_dli.txt successfully" the following should happen.

I believe, because of deserializing, it's giving this error. Please help!!

Can you use gdb to debug the segmentation fault?

[lyj201644070230]

您好，我也遇到跟你同样的问题？请问您解决了吗？

[tuneshverma]

Hi, no I was not able to solve it.

[marcoslucianops]

Try using the new ONNX export method.

Hi! I am also having this problem, only except that I have segmentation fault 9 times out of 10, Is there any way to fix this? I'm using custom yolov8 model, followed the steps in the project(running on DeepStream 6.2)

[marcoslucianops]

Can you send the output from the terminal?
