How to run FedOpt？

[XueBaolu]

Excuse me
I set the cfg like:

fedopt

cfg.expname = 'fedopt'
cfg.federate.share_local_model = False
cfg.federate.online_aggr = False
cfg.federate.method = 'FedOpt'
cfg.fedopt.use = True
cfg.fedopt.optimizer.type = 'SGD'
cfg.fedopt.optimizer.lr = 1.
cfg.fedopt.annealing = False
cfg.fedopt.annealing_step_size = 2000
cfg.fedopt.annealing_gamma = 0.5

模型参数

from federatedscope.fflavg import model_resnet
cfg.model.type = 'convnet5'
cfg.model.out_channels = 62

数据参数

from federatedscope.core.auxiliaries.data_builder import get_data
cfg.data.type = 'femnist'
cfg.data.root = './data'
cfg.data.splits = [0.6, 0.2, 0.2]
cfg.data.splitter = 'lda'
cfg.data.splitter_args = [{'alpha':0.05}]
cfg.data.shuffle = True
cfg.data.batch_size = 128
cfg.data.transform = [['ToTensor'], ['Normalize', {'mean':[0.1307], 'std':[0.3081]}], ['Resize',{'size': [64, 64]}]]

训练参数

cfg.train.optimizer.lr = 0.01
cfg.train.optimizer.weight_decay = 0.0
cfg.grad.grad_clip = 5.0
cfg.early_stop.patience = 10
cfg.criterion.type = 'CrossEntropyLoss'

系统参数

cfg.wandb.use = True
cfg.wandb.client_train_info = False
cfg.use_gpu = True
cfg.seed = 908
cfg.eval.freq = 1
cfg.eval.metrics = ['acc', 'f1']
cfg.eval.best_res_update_round_wise_key = 'test_acc'
cfg.federate.mode = 'standalone'
cfg.federate.make_global_eval = True
cfg.federate.merge_test_data = True
cfg.federate.merge_val_data = True
cfg.federate.total_round_num = 200
cfg.train.batch_or_epoch = 'epoch'
cfg.train.local_update_steps = 3
cfg.federate.client_num = 10
cfg.federate.sample_client_num = -1

But the result of experiment is odd:

Can you help me to debug?
