After I set up the environment, I run this command

However, I met errors.

Did you find the solution? @mf093087
I tried to run YOLO on ROS melodic too and I met the same problem. Does it have something to do with ROS version?
Yes, just try to use chmod +x +python file to give permission

I can't find the python file in the package. Can you post the directory?
Hi! I just solved this problem. I forgot to source the /devel/setup.bash again after compile the workspace. Maybe you can try to source it again?
I found a solution (3/31/22).
Setup: Ubuntu 18.04
ROS Version: Melodic
So after you setup your keys, you are instructed to use the following command to build your package:
git clone --recursive git@github.com:leggedrobotics/darknet_ros.git
^^ This command will not work for ROS Melodic users. You will get as far as the "cannot launch node of type" error with this build. So how I fixed this was downloading the feature/ci-melodic-and-noetic branch. As soon as I built this version in my catkin_ws/src directory, I sourced my workspace and launched a ros command and boom, it worked. So type this command to build the package for Ubuntu 18.04:
git clone --recursive git@github.com:leggedrobotics/darknet_ros.git --branch feature/ci-melodic-and-noetic
I hope this helps! From a fellow stressed out graduate student tired of all these damn bugs on this damn platform lol
@asibarr2 This did not solve the problem!!, the error is persistent..... I tried all the methods available on the internet but unable to solve this error, @asibarr2 if you find any other alternative ... Please do let me know
In my case, after catkin_make, i do rosdep install --from-paths src/ --ignore-src, and success
i face the same issue，have you fix it?
i face the same issue，have you fix it? @hello50505
Hi! My problem was simply due to I forgot to source setup.py in /dev folder of this project... I‘m not sure if we have the some problem. Could you provide more details?
I found a solution
I created another directory and then installed the necessary libraries, later when I built the file...it worked out!!
ERROR: cannot launch node of type [darknet_ros/darknet_ros]: Cannot locate node of type [darknet_ros] in package [darknet_ros]. Make sure the file exists in the package path and permission is set to executable (chmod +x).
I tried many ways but I am unable to find the solution. can anyone help me.
This issue can only be solved by creating a new directory and then deleting the previous libraries installed. now, start all over again by installing the libraries into this new directory! this is how I solved the problem
ps: make sure that you've installed the correct version of libraries compactable with your version of python. and then you will not have any trouble building it!
@ni-r1 ,thank your reply. I just cloned the darknet_ros package and then I used this catkin_make -DCMAKE_BUILD_TYPE=Release. I have no idea about libraries. Do I need to anything else after cloning it.
Hello, Can you help me how you fixed this issue?
I am unable to find the solution. I don't know what is wrong.
setup.py
Hello, I didn't understand what you said exactly. Please help me out.
Can any one help me how to fix the error. ERROR: cannot launch node of type [darknet_ros/darknet_ros]: Cannot locate node of type [darknet_ros] in package [darknet_ros]. Make sure the file exists in the package path and permission is set to executable (chmod +x). I am using ROS-noetic. Thanks in advance.
Is this issue still active?
I got the issue solved. The problem is due to failure of catkin_make due to error in some other packages. After deleting those packages, it worked.

Can you elaborate on that? I'm still facing error even after creating a separate workspace
Can you elaborate on that? I'm still facing error even after creating a separate workspace
And my catkin build is working fine without any failure
@NimishKashyap Sir, How to solve this error in ubuntu 20.04?
