如何导入新编译的python模块?

from sklearn.datasets import load_iris
iris = load_iris() 

import lightgbm as lgb 
lgtrain = lgb.Dataset(iris.data, iris.target)
lgb_clf = lgb.train(
        {
    'objective' : 'regression',
    'metric' : 'rmse',
    'num_leaves' : 350,
    #'max_depth': 14,
    'learning_rate' : 0.017,
    'feature_fraction' : 0.5,
    'bagging_fraction' : .8,
    'verbosity' : -1 ,
    'device' : 'gpu'

},
        lgtrain,
        num_boost_round=3500,
        verbose_eval=100
    )

我想我必须说明地点,但怎么说呢?
