Reduce number of previous frames in training

[karthikkovalam]

Hi @exiawsh. Thanks for your great work. I am trying to train the model using the default config repdetr3d_eva02_800_bs2_seq_24e.py. This uses streaming training. How can I set the number of previous frames to be used during training? I want to use only 1 previous frame and the current frame for both training and validation. Can you please how this can be done?
