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

Question

下载了 Houndify Python 和 C++ 来分别尝试。 + 获得要编译的 C++ 示例，运行 很好。 + sample_text.py 运行很好。

sample_wave.py 和 sample_stdin.py 都失败并出现相同的错误：

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

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

看起来这是Python SDK中的一个错误，但在最新版本0.3.1 (https://docs.houndify.com/sdks#python)中已修复。
