How to use the extracted RGB and flow frames of Kinetics400 to train I3D network?

[MengyuanChen21]

Hello, friends in the community! I need your help!

I am trying to train the I3D network on Kinetics 400, and I find that the training is extremely slow. The log file provided by mmaction2 shows that they only need about 3 days, but I need about 30 days to finish the training process on 8 RTX3090 GPU. It is obviously abnormal. I really want to know what the problem might be.

The command I used is :
bash tools/dist_train.sh configs/recognition/i3d/i3d_imagenet-pretrained-r50-heavy_8xb8-32x2x1-100e_kinetics400-rgb.py 8

Thanks for your time!
