So I'm trying to use image_geometry to convert pixel to 3d coordinates using projectPixelTo3dRay from image_geometry Before using that function, i had to set the parameters as such

cam_info = self.image_sub
img_proc = PinholeCameraModel()
n = img_proc.projectPixelTo3dRay((557,655))

But i get that error when trying to run the code. Can anyone help me out, this is really important

The error also has this bit,which is what K is. You can also read it from the source code

line 42, in fromCameraInfo
self.K = mkmat(3, 3, msg.K)
