Windows错误与python一起使用XGBoost [英] Windows Error using XGBoost with python

问题描述

因此，我正在解决这个机器学习问题(来自之前的Kaggle竞赛练习:

So I'm tackling this machine-learning problem (from a previous Kaggle competition for practice: https://www.kaggle.com/c/nyc-taxi-trip-duration) and I'm trying to use XGBoost but getting an error which I have no clue how to tackle. I searched on google and stack overflow but couldn't find anyone with a similar problem.

我正在通过Anaconda在Spyder IDE中使用python 2.7，并且在Windows 10上安装xgboost软件包时遇到了一些麻烦，因此我不会完全消除它可能是安装错误的想法.但是，我也正在学习有关ML的Udemy课程，我可以在一个小的数据集上很好地使用xgboost，而且我使用的是相同的函数.

I'm using python 2.7 with the Spyder IDE through Anaconda and I'm on Windows 10. I did have some trouble installing the xgboost package so I won't completely erase the idea that it could be an installation error. However I'm also doing a Udemy course on ML and I was able to use xgboost just fine with a small dataset and I'm using the same functions.

代码非常简单:

... import libraries

# import dataset 
dataset = pd.read_csv('data/merged.csv')
y = dataset['trip_duration'].values
del dataset['trip_duration'], dataset["id"], dataset['distance']
X = dataset.values

# Split dataset into training and test sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.25)

# fit XGBoost to training set
classifier = XGBClassifier()
classifier.fit(X_train, y_train)   

输出

但是它会出现以下错误:

Output

However it spits out the following error:

In [1]: classifier.fit(X_train, y_train)
Traceback (most recent call last):

    _check_call(_LIB.XGBoosterUpdateOneIter(self.handle, iteration, dtrain.handle))

WindowsError: [Error -529697949] Windows Error 0xE06D7363

我真的不知道该如何解释，因此对您的帮助将不胜感激.预先感谢

I don't really know how to interpret this so any help would be very appreciated. Thanks in advance

推荐答案

我猜这是因为您使用XGBClassfier而不是XGBRegressor来解决回归问题.

I guess the error is because you are using XGBClassfier instead of XGBRegressor for a regression problem.
