OpenCV in WorldViz

return _cv.CvMat__setitem__(*args)
RuntimeError: openCV Error:
Status=Sizes of input arguments do not match

My guess would be to try looping through the two arrays and setting corresponding elements one at a time rather than trying to set the whole thing at once, e.g.:

for i in range(2):
  for j in range(2):
     transition_matrix[i][j] = A[i][j]
