Error occurs when executing trt.Builder() of tensorRT

AI & Data Science Deep Learning (Training & Inference) TensorRT

Hi!
I want to run tensorrt on darknet_ros, so I’m trying to use trt_yolo_ros.

When I ran the command roslaunch trt_yolo_ros demo.launch, I got an AttributeError. The logs are as follows.

Hi @kubo1,
Can you share the log file?

Thanks!

@AakankshaS
ok!
I deleted the exact same file, but I share the log file when I get the same error.
trt_yolo_ros-2.log (7.9 KB)

Hi @kubo1,
Looks like this issue belongs more to the repo
Hence request you to raise this on the below link

Thanks!

@AakankshaS
Yes, this is the repository I am asking. I thought that maybe the person in charge of nvidia might know, so I was listening to both. Thank you as always.
