Houndify: sample_wave.py error: "unsupported operand type(s) for %: 'bytes' and 'int'"

Question

Downloaded Houndify Python and C++ to try each. + Got the C++ sample to compile and run well. + sample_text.py runs fine.

sample_wave.py and sample_stdin.py both fail with the same error:

$ ./sample_wave.py '...my client ID here...' '...my client key here...' test_audio/whattimeisitindenver.wav

============== test_audio/whattimeisitindenver.wav ===================
Traceback (most recent call last):

Answer 1

It looks like this is a bug in the Python SDK, but it has been fixed in the latest version which is 0.3.1 (https://docs.houndify.com/sdks#python).
