【问题描述】：

我正在使用 Jupyter 执行以下代码，但出现错误

import pandas as pd
from sklearn.tree import DecisionTreeClassifier 

music_data = pd.read_csv('music.csv')
X = music_data.drop(columns=['genre'])
y = music_data['genre']

model = DecisionTreeClassifier()
model.fit(X,y)
music_data

发生错误：

我正在使用 Python 3.8.0 和 anaconda3，请有人告诉我这里出了什么问题

【问题讨论】：

看来你安装了numpy 没有mkl 包。请用np.__config__.show()检查它
如何检查这个，我们应该在命令提示符下运行吗？
你可以用import numpy as np和print(np.__config__.show())写一个python scipt。

【解决方案1】：

从错误日志看来，问题出在这一行：

from scipy.sparse.linalg import lsqr as sparse_lsqr

尝试卸载并重新安装scipy和numpy

卸载：

pip uninstall numpy scipy

安装：

pip install -U numpy scipy
