Question

每次尝试使用scikit-learn类时，我都遇到GradientBoostingRegressor的问题，出现以下错误：

Traceback (most recent call last):
File "C:\Users\rober\Desktop\Privat\Roland_Manu_ProjektBeidl\numerai_datasets\testitest.py", line 11, in <module>
    from sklearn.ensemble import GradientBoostingRegressor

  File "C:\Users\rober\Anaconda3\lib\site-packages\sklearn\__init__.py", line 80, in <module>
    from .base import clone

  File "C:\Users\rober\Anaconda3\lib\site-packages\sklearn\base.py", line 21, in <module>
    from .utils import _IS_32BIT

  File "C:\Users\rober\Anaconda3\lib\site-packages\sklearn\utils\__init__.py", line 24, in <module>
    from . import _joblib

  File "C:\Users\rober\Anaconda3\lib\site-packages\sklearn\utils\_joblib.py", line 8, in <module>
    from joblib import logger

ImportError: cannot import name 'logger' from 'joblib' (unknown location)

我的代码如下

import csv
import pandas as pd
import numpy as np
from sklearn.ensemble import GradientBoostingRegressor

model = GradientBoostingRegressor(learning_rate=0.01, n_estimators=100,
                                      max_depth=5, validation_fraction=0.2, n_iter_no_change=10,
                                      tol=1e-3)

有人可以帮助我吗？我尝试加载外部joblib库，但未成功。

编辑：抱歉，现在显示了整个错误日志。

尝试使用 Anaconda Prompt 重新安装 sklearn：

conda install -c anaconda scikit-learn

Sklearn错误，无法从“ joblib”导入名称“ Logger”
