Thanks for giving us a great code, but when I run ros2 launch yolov8_bringup yolov8.launch.py it shows:

The main problem might be ModuleNotFoundError: No module named 'torch',But I have torch in conda env, you know where might be the problems? Thank you.
(pytorch) ragnar@ragnar:~$ pip list |grep torch
torch 2.0.1
torchaudio 2.0.2
torchmetrics 0.8.0
torchvision 0.15.2

Hi @Ragnar7982, I don't think mixing conda envs and ROS is a good idea. Have you tried to use this repo without conda?

[Ragnar7982]

@mgonzs13
I tried once before, but I run it today it shows ERROR:
[debug_node-3] ModuleNotFoundError: No module named 'torch'
[ERROR] [debug_node-3]: process has died [pid 14347, exit code 1, cmd '/home/ragnar/yolo_ws/install/yolov8_ros/lib/yolov8_ros/debug_node --ros-args -r __node:=debug_node -r __ns:=/yolo --params-file /tmp/launch_params_lat3ryi1 -r /oakd/rgb/preview/image_raw:=/oakd/rgb/preview/image_raw -r detections:=tracking'].

That 's way I create conda env? If I run yolo without conda env, it shows the same error, so I don't know where is the problem.
Please let me know if you know how to fix it, thank you.

[mgonzs13]

Are you installing torch with pip when not using conda? Dopython-is-python3? Have you tried installing torch with pip3 and not using a conda env?

[AnatoliyZabrovskiy]

I have the same problem! Does anyone have a solution? Thanks!
