1 问题描述

在运行wav2lip训练时，出现如下错误：

D:\.conda\wav2lip\python.exe D:/ml/wav2lip384/parallel_syncnet_tanh.py --data_root D:/ml/Wav2Lip/data/25fps_out/ --checkpoint_dir syncnet_checkpoints/ --checkpoint_path
Traceback (most recent call last):
  File "D:\.conda\wav2lip\lib\site-packages\requests\compat.py", line 11, in <module>
    import chardet
ModuleNotFoundError: No module named 'chardet'

During handling of the above exception, another exception occurred:
