Unable to run tune_blockmatcher, initialize trackbars getting got float value

[r-rajsingh]

I tried a lot, even referred to open cv documentation for setting the correct values in "cv2.StereoSGBM_create()" function. Still, I m getting the error "TypeError: integer argument expected, got float". Please if anyone could help me.

Below are the values that I have set. I am even getting this error by the default code.
