Python raspberry pi上的音频录制错误，输入溢出

python raspberry-pi

Python raspberry pi上的音频录制错误，输入溢出,python,raspberry-pi,alsa,pyaudio,Python,Raspberry Pi,Alsa,Pyaudio,我在一个语音识别系统上工作了一段时间，现在我正试图把它移到我的树莓皮上。我在尝试录制时遇到以下错误。请看一看。我的代码在我的电脑上运行得很好。所以我不知道这是否真的是内存错误或软件包问题。无论如何，我怎样才能解决这个问题 FORMAT = pyaudio.paInt16 CHANNELS = 2 RATE = 44100 CHUNK = 1024 RECORD_SECONDS = 3 要记录的代码是 audio = pyaudio.PyAudio() stream = aud

我在一个语音识别系统上工作了一段时间，现在我正试图把它移到我的树莓皮上。我在尝试录制时遇到以下错误。请看一看。我的代码在我的电脑上运行得很好。所以我不知道这是否真的是内存错误或软件包问题。无论如何，我怎样才能解决这个问题

FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
CHUNK = 1024
RECORD_SECONDS = 3

要记录的代码是

    audio = pyaudio.PyAudio()

    stream = audio.open(format=FORMAT, channels=CHANNELS,
                        rate=RATE, input=True,
                        frames_per_buffer=CHUNK)

    time.sleep(2.0)
    print("recording...")
    frames = []

    for i in range(0, int(RATE / CHUNK * (RECORD_SECONDS + 1))):
        data = stream.read(CHUNK)
        frames.append(data)
    print("finished recording")

错误如下
