问题描述
嗨，我在运行以下代码后，
tfms = get_spectro_transforms(size=(64,128),mask_time=False,mask_frequency=False,roll=False);
audios_fase_1 = AudioList.from_folder(pt,config=cfg)\
.split_by_folder(train='training',\
valid='test')\
.label_from_func(get_y).transform(tfms)
db_fase_1 = audios_fase_1.databunch(bs=256,num_workers=8)
出现以下问题。
IndexError Traceback (most recent call last)
