Error: return int(self._data[1]) IndexError: list index out of range

[yhc1994]

Hi,

I have edited my list file under the for mat video_frame_path 100 10
But I will get a new error immediately after epoch 4.
It will return int(self._data[1]) IndexError rather than self._data[2]
The code is attached.

clipping gradient: 45.87702178955078 with coef 0.43594807386398315
Freezing BatchNorm2D except the first one.
