AttributeError: 模块“xgboost”没有属性“XGBRegressor”

Question

I am trying to run xgboost using spyder and python, but I keep getting this error:

AttributeError: module 'xgboost' has no attribute 'XGBRegressor'

Here is the code:

import xgboost as xgb 

xgb.XGBRegressor(max_depth=3, learning_rate=0.1, n_estimators=100, silent=True, 
                 objective='reg:linear', gamma=0, min_child_weight=1, 
                 max_delta_step=0, subsample=1, colsample_bytree=1, 
                 seed=0, missing=None)

Error is

Traceback (most recent call last):

  File "<ipython-input-33-d257a9a2a5d8>", line 1, in <module>
    xgb.XGBRegressor(max_depth=3, learning_rate=0.1, n_estimators=100, silent=True,

AttributeError: module 'xgboost' has no attribute 'XGBRegressor'

I have Python 3.5.2 :: Anaconda 4.2.0 (x86_64)

How do I solve this?

Answer 1

We probably have the same problem.

I solved it by telling Python explicitly where to find xgboost library.

The reason is that I have more than one scripts with the name xgboost.py. Python might have imported one of them mistakenly, so that it cannot find the definition of 'XGBRegressor'.

Here is the command I used:

export PYTHONPATH=PATH_TO_YOUR_setup.py_file

For me, PATH_TO_YOUR_setup.py_file is ~/xgboost/python-package

Answer 2

由于您的dir调用基本上丢失了所有内容，因此我怀疑，无论您从哪里启动脚本，都有一个xgboost子文件夹，其中包含一个空的__init__.py ，该子文件夹首先由import找到。

Answer 3

I had the exact same problem with Python 3.6.2 and Anaconda 1.6.8 on windows10 64bits (fall creator update)

To get it to work, here is what I did :

1/ Uninstall xgboost from within anaconda, in the chosen environement.

2/ Manually deleted the xgboost directory in C:\\ProgramData\\Anaconda3

3/ Downloaded xgboost from This page

4/ From Anaconda, launch a command prompt from (from the environment you want xgboost into of course)

5/ CD to the directory you downloaded the whl file to and type : pip install xgboost‑0.6+20171121‑cp36‑cp36m‑win_amd64.whl (or the exact name of the file you downloaded)

I did all these steps and xgboost worked properly

Answer 4

就我而言，我很容易使用

from xgboost import XGBRegressor

Answer 5

Probably there are many files with the same name of "xgboost".That is why python tries to load one of these instead of the original package file.

Tip Check your working directory and see if there are any py files with the same name of "xgboost.py". If so, Change the name to something else.

Answer 6

I had to make sure to follow all the download instructions from the xgboost website. After installing and compiling, i forgot to run these. https://xgboost.readthedocs.io/en/latest/build.html#python-package-installation
