python Deepspeech TypeError：__init__()需要2个位置参数，但给出了3个

问题描述

我正在尝试实施 deepspeech，作为实施的一部分，我正在尝试运行以下代码。我已经安装了 python3 和 deepspeech-0.9.3

在运行以下代码时，我收到一个错误 line 17,in <module> model = deepspeech.Model(MODEL_FILE_PATH,BEAM_WIDTH) TypeError: __init__() takes 2 positional arguments but 3 were given

import deepspeech
import numpy as np
import os
import pyaudio
import time

# DeepSpeech parameters
DEEPSPEECH_MODEL_DIR = 'deepspeech-0.9.3-models'
MODEL_FILE_PATH = os.path.join(DEEPSPEECH_MODEL_DIR,'output_graph.pbmm')
BEAM_WIDTH = 500
LM_FILE_PATH = os.path.join(DEEPSPEECH_MODEL_DIR,'lm.binary')
TRIE_FILE_PATH = os.path.join(DEEPSPEECH_MODEL_DIR,'trie')
LM_ALPHA = 0.75
LM_BETA = 1.85

# Make DeepSpeech Model
model = deepspeech.Model(MODEL_FILE_PATH,BEAM_WIDTH)
model.enableDecoderWithLM(LM_FILE_PATH,TRIE_FILE_PATH,LM_ALPHA,LM_BETA)

# Create a Streaming session
context = model.createStream()

# Encapsulate DeepSpeech audio Feeding into a callback for PyAudio
text_so_far = ''
def process_audio(in_data,frame_count,time_info,status):
    global text_so_far
    data16 = np.frombuffer(in_data,dtype=np.int16)
    model.FeedAudioContent(context,data16)
    text = model.intermediateDecode(context)
    if text != text_so_far:
        print('Interim text = {}'.format(text))
        text_so_far = text
    return (in_data,pyaudio.paContinue)

# PyAudio parameters
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 16000
CHUNK_SIZE = 1024

# Feed audio to deepspeech in a callback to PyAudio
audio = pyaudio.PyAudio()
stream = audio.open(
    format=FORMAT,channels=CHANNELS,rate=RATE,input=True,frames_per_buffer=CHUNK_SIZE,stream_callback=process_audio
)

print('Please start speaking,when done press Ctrl-C ...')
stream.start_stream()

try: 
    while stream.is_active():
        time.sleep(0.1)
except KeyboardInterrupt:
    # PyAudio
    stream.stop_stream()
    stream.close()
    audio.terminate()
    print('Finished recording.')
    # DeepSpeech
    text = model.finishStream(context)
    print('Final text = {}'.format(text))

解决方法

您要么提供了更多参数，要么没有在 init

中使用 self 关键字 ,

您正在使用已弃用的代码。

您正在尝试使用 0.9 模型和 0.6 代码。从 0.7 开始，您不再使用 lm.binary 并尝试使用语言模型。而且你的代码还有很多错误。

Check the 0.9 docs。

也许使用 current examples. 之一，具体取决于您的用例是什么。
