Set type for fromarray() in opencv for python

I am using Python 2.7 and opencv 2.1.

I have a numpy array and I want to convert it to an opencv matrix of type "cv.CV_32FC1". How can I set the type ?

"CreateMat()" allows for explicit type setting but "fromarray()" doesnt. If I just apply fromarray on a float array the type check fails (one of the next modules performs a specific type check for CV_32FC1)

thanks !

You can try the following:

dest = cv.createMat(r, c, cv.CV_32FC1)
src = cv.fromarray(your_np_array)
cv.Convert(src, dest)

where your numpy array has r rows and c columns.
