命令是:
python script/experiment/train_ml.py -d '((2,), (3,))' -r 1 --num_models 2 --dataset combined --ids_per_batch 32 --ims_per_id 4 --normalize_feature false -gm 0.3 -glw 1 -llw 0 -idlw 0 -pmlw 0 -gdmlw 1 -ldmlw 0 --base_lr 2e-4 --lr_decay_type exp --exp_decay_at_epoch 151 --total_epochs 300

您好,多谢关注!

模型在ckpt.pth中,保存checkpoint的代码是save_ckpt(modules_optims, ep + 1, 0, cfg.ckpt_file),参见这里,其中modules_optims = models + optimizers,参见这里。这里有两个模型在训练,还有两个optimizer,所以modules_optims是长度为4的list。根据save_ckpt实现,存到磁盘的是一个dict,其中有一项是state_dicts,即modules_optims的参数,所以想要取得第一个模型的参数,可以这样做:

map_location = lambda storage, loc: storage
ckpt = torch.load(ckpt_file, map_location=map_location)
model_weight = ckpt['state_dicts'][0]
