I am trying to use the demucs package in python and i have already installed the demucs package as well but suddenly i am getting this issue.

this below is my code which i am trying to use.

`
import os
from tqdm import tqdm
import torch
from demucs import pretrained
from demucs.apply import apply_model
import torchaudio

def separate_vocals(input_folder, output_folder):
if not os.path.exists(output_folder):
os.makedirs(output_folder)

wav_files = [f for f in os.listdir(input_folder) if f.endswith('.wav')]

model = pretrained.get_model('htdemucs')  
model.to('cuda' if torch.cuda.is_available() else 'cpu')

for wav_file in tqdm(wav_files, desc="Processing files"):
    input_path = os.path.join(input_folder, wav_file)
    
    wav, sr = torchaudio.load(input_path)
    wav = wav.to('cuda' if torch.cuda.is_available() else 'cpu')
    sources = apply_model(model, wav, shifts=1, split=True, overlap=0.25)
    
    vocals = sources[0]  
    output_path = os.path.join(output_folder, wav_file)
    torchaudio.save(output_path, vocals.cpu(), sr)

`

I am getting the below error on my screen.

I was expecting the model to take audios from a folder perform vocal separation on a audio file, and save that vocals file to a new folder.

I also tried installing the omegaconf module as

pip install omegaconf

still receiving the same error.
