我已经在picovoice中创建了一个帐户，并收到了一个访问密钥，但当我尝试放置我的ppn文件的路径时，它显示了一个错误：`

[ERROR] loading keyword file at 'C:\Users\Priyam\Desktop\hey keyazip' failed with 'IO_ERROR'
Traceback (most recent call last):
  File "e:\Personal Project\import struct.py", line 13, in <module>
    porcupine = pvporcupine.create(access_key='access key',

    raise self._PICOVOICE_STATUS_TO_EXCEPTION[status]()
pvporcupine.porcupine.PorcupineIOError

代码为：`

porcupine=None
paud=None
audio_stream=None

try:
    access_key="access key" 
    porcupine = pvporcupine.create(access_key='access key',
    keyword_paths=['C:\\Users\Priyam\Desktop\hey keyazip'],keywords=['hey keya']) #pvporcupine.KEYWORDS for all keywords
    paud=pyaudio.PyAudio()
    audio_stream=paud.open(rate=porcupine.sample_rate,channels=1,format=pyaudio.paInt16,input=True,frames_per_buffer=porcupine.frame_length)
    while True:
        keyword=audio_stream.read(porcupine.frame_length)
        keyword=struct.unpack_from("h"*porcupine.frame_length,keyword)
        keyword_index=porcupine.process(keyword)
        if keyword_index>=0:
            print("hotword detected")
            

finally:
    if porcupine is not None:
        porcupine.delete()
    if audio_stream is not None:
        audio_stream.close()
    if paud is not None:
        paud.terminate()

我尝试了上面的代码和picovoice本身提供的代码，但我面临着同样的问题
