Error when try to rosrun whycon about whycon

[protobits]

Hello,
the message about the YML file is only a warning. This file is created during whycon calibration stage which allows you to map 3D positions to 2D positions. It should not impede you from getting an output.
Please check output topics (image output and target poses) to verify whycon is working.

I ran rostopic list and received the following outputs:
/whycon/context
/whycon/image_out
/whycon_poses
/whycon/projection
But I still don't have anything appearing in the rviz viewer, it's just the blank grid.

I'm assuming you subscribed on rviz on the corresponding topic right? Have you checked the image topic?

I'm sorry, I'm really new to ROS. What exactly do you mean "subscribed rviz on the corresponding topic"?

[protobits]

Sorry, but I cannot give you support on learning ROS. There is enough information out there.If you have a specific problem with whycon you can open a corresponding issue.

I also posted the question on here : https://answers.ros.org/question/290489/error-in-loading-whycon-file/
I did solve my issue (not seeing anything in rviz and the missing transforms.yml). I had to run whycon.rviz rather than just rviz and I had to subscribe to PoseArray. The whycon_transforms.yml was created by running set_axis.

Hello, I still don't understand how to solve these problems. Do you have detailed troubleshooting steps? This software is very difficult to install. . .

sir,while installing whycon in ubuntu 16.04 with comaand "git clone http://www.github.com/lsre/whycon.git"
and they asked for username and password.I entered those of github account.
And the output is "Repository not found"
