Error: Could not execute GraphicsMagick/ImageMagick: identify "-ping" "-format" "%wx%h"

Question

I'm trying to find the dimensions of the images in a production machine.It returns error.

Could not execute GraphicsMagick/ImageMagick: identify "-ping" "-format" "%wx%h" "uploads/userPhoto-1499669685192.png" this most likely means the gm/convert binaries can't be foundsize==undefined

But it is working fine in local machine and I have already uploaded modules in production machine which are same as local machine.
