每次运行都是在进度条快完成时报exception，如：
generate wave
{| ████████████████ 47500/48000 | Batch Size: 5 | Gen Rate: 4.4kHz | }
C:\Users\xxxxx\AppData\Local\Programs\Python\Python310\lib\site-packages\numpy\lib\arraypad.py:736: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray.
array = np.asarray(array)
Caught exception: ValueError('The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()')

我把此文件上方的from models.vocoder import inference as vocoder改成了from models.vocoder.wavernn import inference as vocoder（否则import inference会直接报错）

请问这是什么原因呢？谢谢！
