你好,想请问下跑12G的模型,不支持多GPU么? 我执行了这个指令python3 tools/train_net.py --cfg ./configs/config_car_12g.py --savemodel ./outputs/MODEL_dsgn_v1 -btrain 8 -d 0-7,然后还是出现了 RuntimeError: CUDA out of memory. Tried to allocate 674.00 MiB (GPU 0; 11.78 GiB total capacity; 9.14 GiB already...

请问loss函数中add_alpha = 0.2,add_beta = 0.2这两个参数会随着模型的训练更新么,还是设置好就不变了呢?
