获取此文件[Errno 20]不是目录：'./data//.DS_Store'

Question

我只是预处理我的数据，但是每次尝试加载数据并将其转换为mfcc时，都会出现错误。

没有找到适合我的解决方案

转换部分

def wav2mfcc(file_path, n_mfcc=20, max_len=11):
wave, sr = librosa.load(file_path, mono=True, sr=None)
wave = wave[::3]
mfcc = librosa.feature.mfcc(wave, sr=16000, n_mfcc=n_mfcc)

# If maximum length exceeds mfcc lengths then pad the remaining ones
if (max_len > mfcc.shape[1]):
    pad_width = max_len - mfcc.shape[1]
    mfcc = np.pad(mfcc, pad_width=((0, 0), (0, pad_width)), mode='constant')

# Else cutoff the remaining parts
else:
    mfcc = mfcc[:, :max_len]

return mfcc

运行代码

save_data_to_array(max_len=config.max_len, n_mfcc=config.buckets)

我遇到错误
