我提取了一些在kaggle(linux)上运行的ML代码,并尝试在Windows机器上的jupyter笔记本中运行它。这是代码(其中一些):
##### RUN XGBOOST
import xgboost as xgb
print("\nSetting up data for XGBoost ...")
# xgboost params
xgb_params = {
'eta': 0.037,
'max_depth': 5,
'subsample': 0.80,
'objective': 'reg:linear',
'eval_metric': 'mae',
'lambda': 0.8,
'alpha': 0.4,
'base_score': y_mean,
'silent': 1
}
#### These lines were causing the folloing error on 9/1/2017:
# AttributeError: module 'xgboost' has no attribute 'DMatrix'
dtrain = xgb.DMatrix(x_train.values, y_train.values)
dtest = xgb.DMatrix(x_test)
num_boost_rounds = 250
print("num_boost_rounds="+str(num_boost_rounds))
# train model
print( "\nTraining XGBoost ...")
model = xgb.train(dict(xgb_params, silent=1), dtrain,
num_boost_round=num_boost_rounds)
print( "\nPredicting with XGBoost ...")
xgb_pred1 = model.predict(dtest)
print( "\nFirst XGBoost predictions:" )
print(pd.DataFrame(xgb_pred1).head())
收到以下错误:
---------------------------------------------------------------------------

---> 19 dtrain = xgb.DMatrix(x_train.values, y_train.values)
20 dtest = xgb.DMatrix(x_test)

这很奇怪,因为我一直将Linux机器的xgboost模型拉到窗口。我找不到任何关于如何修复互联网的信息,所以我想知道是否有人知道如何解决?
答案 0 :(得分:2)
我们可能遇到同样的问题。
我通过告诉Python明确在哪里找到xgboost库来解决它。
原因是我有多个名为xgboost.py的脚本。 Python可能错误地导入了其中一个,因此无法找到'DMatrix'的定义。
这是我使用的命令:
export PYTHONPATH=~/xgboost/python-package
您应该将'〜/ xgboost / python-package'更改为/xgboost/python-package/setup.py文件所在的文件夹。
