Hello,

Can you help me to correct this error,
I use a USB camera as input.
roslaunch yolov4_trt_ros video_source.launch input:=v4l2://3
RLException: [video_source.launch] is neither a launch file in package [yolov4_trt_ros] nor is [yolov4_trt_ros] a launch file name
The traceback for the exception was written to the log file

Hi,

Did you source your workspace,

$ cd ~/catkin_ws
$ source devel/setup.bash

Minion40 · 2021-04-21T13:40:58Z

cd /catkin_ws
procomm@procomm-desktop:/catkin_ws$ source devel/setup.bash

Can i check if you are able to run the other launch files (yolov4_trt.launch)? It could be that the video_source node is not built properly when you ran catkin_make. Maybe you can check that also

i think there is something wrong with your catkin_ws as it does not seem like its building any of the nodes required. Can i check if you have installed all the dependencies required? Also, may I know your environment?

Hardware: Jetson Nano
Jetpack version: 4.3
ROS version: Melodic

You can also try creating another workspace and building the ROS package again there.

Hi, could you try shifting the entire yolov4_trt_ros into another workspace and follow the steps again to see if its works,

# create another workspace
$ mkdir -p yolo_ws/src

# copy the existing package to the new workspace
$ cp -r ~/catkin-ws/src/yolov4_trt_ros/ ~/yolo_ws/src

# build the package using catkin build instead (install the catkin build system first)
$ sudo apt-get install ros-melodic-catkin python-catkin-tools 
$ cd ~/yolo_ws && catkin build
$ source ~/yolo_ws/devel/setup.bash

Follow the rest of the instructions in the README file and run the launch files again. Let me know if that works!

are you able to find the package using roscd?

$ roscd yolov4_trt_ros

im afraid your catkin_make is not properly building the package. could you post the log for the catkin_make or catkin build?

im not able to see the attachment. this error is related to your catkin build system as it is not building the package properly. You can try reinstalling ROS melodic again or solve the catkin build system.

Hey, im guessing you are responding to the github email notifications and not on the github issues tab directly. This is probably why Im not able to access any of the links/attachments you are sending. Could you respond directly on Github? Thank you. — You are receiving this because you authored the thread.

it looks like your ros installation is okay and you are not missing any important steps. Can i confirm that running other nodes (such as the ones in ROS tutorial page) works for you? I suspect this might be a ROS issue and not this package.
