what are the commit head numbers of yolov5 and tensorrtx?

i have successfully convert .pt to .engine ,but when run LD_PRELOAD=./libcustomOp.so deepstream-app -c deepstream_app_config_yoloV5.txt got errors as follows

_ERROR: ld.so: object './libcustomOp.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Hi @niuwenju, I too am stuck at the same error since yesterday. Please share the solution if you get success in solving it. I even replaced the libcustomOp.so with libnvdsinfer_custom_impl_Yolo.so created recently. Getting the same error EXCEPT your _ERROR: ld.so: object './libcustomOp.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored since libnvdsinfer_custom_impl_Yolo.so is found.

NOTE: When I replaced both hardwswich.cu and yololayer.cu from tensorrt/yolov5 with that from this repository, I got the following error:

However, when I replaced only the hardswich.cu and NOT yololayer.cu, it ran smoothly, generated the engine file as well and helped reach the final stage.

@DanaHan please provide a viable solution / insight for this problem. Thanking you in anticipation!

[niuwenju]

please replace hardswich.cu and yololayer.cu in tensorrtx/yolov5, after make and dosudo ./yolov5 -s you will get 'yolov5s.engine' and 'libmyplugin.so' , and then run deepstream demo with LD_PRELOAD=<path to libmyplugin.so> deepstream-app -c <app-config>

[niuwenju]

or you can copy all files in this repository except Deepstream 5.0 in tensorrtx/yolov5

[PareshKamble]

Dear @niuwenju, thank you for your quick response.

Do we have to replace hardswich.cu and yololayer.cu in tensorrtx/yolov5 AFTER make and BEFORE doing sudo ./yolov5 -s or in some other chronology?

And what should be the app-config file? config_infer_primary_yoloV5.txt or deepstream_app_config_yoloV5.txt

Thanking you in anticipation!

[niuwenju]

replace hardswich.cu and yololayer.cu before cmake .. and app-config means deepstream_app_config_yoloV5.txt

[PareshKamble]

Dear @niuwenju, Thank you for your response. I managed to run the sample video.

Hi, i am trying to run this with Deepstream6 with tensorRT8.2.0.

Just for information, If i copy hardswich.cu and yololayer.cu to tensorrtx/yolov5 then "make" is not happening. It through error with TensorRT.

But when i do not copy yololayer.cu but only hardswich.cu, then i am able to make and also able to run. Not sure why.
