ValueError: Expected input batch_size (32) to match target batch_size (1).

I tried to change the way of sample frame form the "dict(type='SampleFrames', clip_len=32, frame_interval=2, num_clips=1)," to "dict(type='SampleFrames', clip_len=1, frame_interval=1, num_clips=32)," But get the above error. Where should I also make change?
