我正在使用VITS培训，但在手电筒填充时出现以下异常：

AssertionError: 4D tensors expect 4 values for padding

虚拟仪器系统链接：https://github.com/jaywalnut310/vits
VITS日语链接：https://github.com/innnky/vits-japanese
torch的版本为1.6.0，来自requirements.txt
命令：（test.json与VITS-Japanese中的nan.json相同）

python train.py -c config/test.json -m test

错误：

我已经跟踪了输入的大小。
data_utils. py. get_audio（）中的原始音频：

torch.Size([69506, 2])

data_utils. py. get_audio（）中解压缩（0）后的音频规范：

torch.Size([1, 69506, 2])

y.在熔化_处理. py.谱图_ Torch （）中解压缩（1）：

torch.Size([1, 1, 69506, 2])

填充大小与默认配置相同（（1024 - 256）/2）：

(384,384)

我没有修改VITS代码，所以Tensor大小和填充大小应该正确。
或者我需要对输入的wav文件做些什么吗？
