output_size not equal 1

[CCjiahao]

output_details = interpreter.get_output_details()
output_size, output_zero_point = output_details[0]['quantization']
##### output_size != 1
# This led to me having to get real out by zooming, as follows:
out_true = out * output_size

The out_scale of the tflite model I derived from is not equal to 1, whether this has an impact at the final stage.

If you can avoid this additional rescale of the output it would be better, in any case it will not work well if the output itself is quantized to 8 bits
