Unable to run camera_calibration cameracalibration.py

[zactodd]

Hello,

I was running using melodic and using my laptop camera.

I ran this

rosrun camera_calibration cameracalibrator.py --size 8x6 --square 0.108 image:=/cv_camera/image_raw camera:=/cv_camera

These are the available topic

/cv_camera/camera_info
/cv_camera/image_raw
/cv_camera/image_raw/compressed
/cv_camera/image_raw/compressed/parameter_descriptions
/cv_camera/image_raw/compressed/parameter_updates
/cv_camera/image_raw/compressedDepth
/cv_camera/image_raw/compressedDepth/parameter_descriptions
/cv_camera/image_raw/compressedDepth/parameter_updates
/cv_camera/image_raw/theora
/cv_camera/image_raw/theora/parameter_descriptions
/cv_camera/image_raw/theora/parameter_updates

this is the error msg
