Gpu memory usage

[brkyc3]

Hi thanks for tutorial , i want to try this, with part of 20bn-jester data on colab.But even though i use batch size of 64 , i getting OOM error on GPU. What hardware do you use for training and how long it takes to complete 1 epoch on all dataset ?

I used 4 1080TI GPU. I would like to remind you something important. In contrast to RGB images, videos require significantly more space. 1 batch = size of the batch * number of frames in your video * size of the image (W * H * C). For instance; a batch size of 64 videos requires significantly more memory than a batch of 64 images.
