Obsolete use of method "fromstring" in pyniryo\vision\image_functions.py:388 -> replace with "frombuffer" method

Error when use vision.uncompress_image(...)

ValueError: The binary mode of fromstring is removed, use frombuffer instead

You have to replace in "pyniryo\vision\image_functions.py" line 388

388: np_arr = np.fromstring(compressed_image, np.uint8)

by

388: np_arr = np.frombuffer(compressed_image, np.uint8)
