将文件保存到特定文件夹。程序走错了路

  • 772

我需要从 'D:\Study\Progs\test\samples' 中获取文件，并在处理存储在 'D:\Study\Progs\test"input value"' 之后，但在 "name = os.path.abspath" 行之后（文件）”程序采用错误路径“D:\Study\Progs\test\file.wav”而不是“D:\Study\Progs\test\samples\file.wav”，可能是什么原因？

import librosa.display
import matplotlib.pyplot as plt
import os


pa = "./"
save = pa+input()
os.mkdir(save)
for file in os.listdir("./samples"):
    if file.endswith(".wav"):
        print(file)
        name = os.path.abspath(file)
        ss = os.path.splitext(name)[0]+".png"
        print(name)
        audio = name
        x, sr = librosa.load(audio, mono=True, duration=5)
        save_path = os.path.join(save, ss)
        X = librosa.stft(x)
        Xdb = librosa.amplitude_to_db(abs(X))
        plt.figure(figsize=(20, 10))
        librosa.display.specshow(Xdb, sr=sr)
        plt.savefig(save_path)
python

    在谷歌上找到所有选项之后，我想出了以下工作版本......

    import librosa.display
import matplotlib.pyplot as plt
import os
from pathlib import Path

cwd = Path.cwd()
print("Vvedite directoriu dlya sohraneniya resultatov:")
sf = input()
save_folder = cwd / sf
print("Vvedite nazvanie directorii s primerami .wav failov:")
smpl = input()
sample_dir = cwd / smpl
os.mkdir(save_folder)

for file in sample_dir.glob("*.wav"):
    print(file)
    base = os.path.basename(file)
    outfile = os.path.splitext(base)[0] + ".png"
    print(f"->{outfile}")
    audio = file
    x, sr = librosa.load(audio, mono=True, duration=5)
    save_path = os.path.join(save_folder, outfile)
    X = librosa.stft(x)
    Xdb = librosa.amplitude_to_db(abs(X))
    plt.figure(figsize=(20, 10))
    librosa.display.specshow(Xdb, sr=sr)
    plt.savefig(save_path)

  2. import librosa.display
import matplotlib.pyplot as plt
import os


pa = "./"
save = pa+input()
os.mkdir(save)
samples = "./samples"
os.chdir(samples)
for file in os.listdir("./samples"):
    if file.endswith(".wav"):
        print(file)
        name = os.path.abspath(file)
        ss = os.path.splitext(name)[0]+".png"
        print(name)
        audio = name
        x, sr = librosa.load(audio, mono=True, duration=5)
        save_path = os.path.join(save, ss)
        X = librosa.stft(x)
        Xdb = librosa.amplitude_to_db(abs(X))
        plt.figure(figsize=(20, 10))
        librosa.display.specshow(Xdb, sr=sr)
        plt.savefig(save_path)
