Cannot run speech streaming example now · Issue #484 · GoogleCloudPlatform/python-docs-samples

I could run the all speech api examples without any error until this morning, however, I got an error when I ran speech_streaming.py:

Traceback (most recent call last):
  File "speech_streaming.py", line 157, in <module>
    main()
  File "speech_streaming.py", line 149, in main
    request_stream(stop_audio), DEADLINE_SECS))
  File "speech_streaming.py", line 125, in listen_print_loop
    for resp in recognize_stream:

I tried to run it both on Ubuntu 16.04 and on OS X Yosemite, but the result was same.

Does anyone know the solution for this?
