Hello, Does anyone know how to save, write, convert, etc an Opencv Mat into a YAML file using python?

I tried with cv.Save but it tells me "Cannot identify type of 'structPtr'", and with ImWrite it tells me error: "(-2) could not find a writer for the specified extension in function imwrite"

Thanks a lot for your help.

please, avoid the outdated cv module in python at all cost . it is no more available in current 3.0

can't you just use numpy to save it to a text file ?

I had the same problem. Wrap the numpy array with cv.fromarray()

import numpy 
import cv  
a = numpy.ones((5,5,1),float)
cv.Save("a.xml",cv.fromarray(a))

It is depreciated functionality but ATM works.
