python中编写config文件并及时更新的方法_python

class DefaultConfig(object):

    # dataset划分
    batch_size = 40
    train_pct = 0.7
    vali_pct = 0.2
    test_pct = 0.1
    
    #learning rate
    learning_rate = 1e-3
    
    # Training data
    train_path = r"../data/train"
    target_path_metric = r"../data/targets"

import config  # import进来
reload(config)  ################## 注意这里必须reload！！
from config import DefaultConfig	# 引入class

opt = DefaultConfig()		# 实例config对象

# 这里名字最好保持和clas内部一致，方便检查
batch_size = opt.batch_size
train_pct = opt.train_pct
vali_pct = opt.vali_pct
test_pct = opt.test_pct

import config  # import进来
reload(config)  ################## 注意这里必须reload！！
