You can use cv2 FONT HERSHEY SIMPLEX instead of cv2 CV FONT HERSHEY SIMPLEX in current opencv version

I had a similar problem  I would suggest using the PIL library in python as it draws the text in any given font  compared to limited fonts in OpenCV  With PIL you can choose any font installed on your system   from PIL import ImageFont  ImageDraw  Image import numpy as np import cv2  image   cv2 imread  lena png      Convert to PIL Image cv2 im rgb   cv2 cvtColor image  cv2 COLOR BGR2RGB  pil im   Image fromarray cv2 im rgb   draw   ImageDraw Draw pil im     Choose a font font   ImageFont truetype  Roboto-Regular ttf   50     Draw the text draw text  0  0    Your Text Here   font font     Save the image cv2 im processed   cv2 cvtColor np array pil im   cv2 COLOR RGB2BGR  cv2 imwrite  result png   cv2 im processed    result png

I know this is a really old question but i think i have a solution In the newer versions of openCV fonts are repesented by a number like this      FONT HERSHEY SIMPLEX   0      FONT HERSHEY PLAIN   1      FONT HERSHEY DUPLEX   2      FONT HERSHEY COMPLEX   3      FONT HERSHEY TRIPLEX   4      FONT HERSHEY COMPLEX SMALL   5      FONT HERSHEY SCRIPT SIMPLEX   6      FONT HERSHEY SCRIPT COMPLEX   7      FONT ITALIC   16   so all you have to do is replace the font name with the corresponding number  cv2 putText image  Hello World       x y   0  2  255    again i know its an old question but it may help someone in the future

This code uses cv2 putText to overlay text on an image   You need NumPy and OpenCV installed   import numpy as np import cv2    Create a black image img   np zeros  512 512 3   np uint8     Write some Text  font                     cv2 FONT HERSHEY SIMPLEX bottomLeftCornerOfText    10 500  fontScale                1 fontColor                 255 255 255  lineType                 2  cv2 putText img  Hello World         bottomLeftCornerOfText       font       fontScale      fontColor      lineType    Display the image cv2 imshow  img  img    Save image cv2 imwrite  out jpg   img   cv2 waitKey 0

This is indeed a bit of an annoying problem  For python 2 x x you use   cv2 CV FONT HERSHEY SIMPLEX   and for Python 3 x x   cv2 FONT HERSHEY SIMPLEX   I recommend using a autocomplete environment pyscripter or scipy for example   If you lookup example code  make sure they use the same version of Python if they don t make sure you change the code
