CUDA out of memory.

[HitZhouzhou]

When I run python ./code/train_e_topic.py --config-name conf_e_topic_bge use_wandb=false all_data=false,I get the CUDA out of memory problems . I have 8 RTX4090,having 24GiB of each one,but the cuda memory is not enough,how can I use 8 GPU to train the model together.Thank you very much
