Computer Vision - Text Recognition - OcrResult object DeserializationError / unicode #2769
Description
I have modified the example image_analysis_in_stream at https://github.com/Azure-Samples/cognitive-services-python-sdk-samples/blob/master/samples/vision/computer_vision_samples.py to rather carry out OCR, i.e.
with open(os.path.join(IMAGES_FOLDER, "image.jpg"), "rb") as image_stream:
image_response = client.recognize_printed_text_in_stream(image_stream,language='en')
This gives the following Traceback:

Line 962 requires a response code of 200, so can I assume image_stream is valid?
How do I then deserialize OcrResult to JSON?
Is this an API version mismatch..?
Thanks for any speedy help.
