Question

我正在使用带有python 3的anaconda。在spyder中我运行以下代码

import pandas as pd
import quandl
import math
import numpy as np
from sklearn import preprocessing, cross_validation, svm
from sklearn.leanear_model import LearnRegression


df = quandl.get('WIKI/GOOGL')
df = df[['Adj. Open','Adj. High','Adj. Low','Adj. Close','Adj. Volume',]]
df['HL_PCT'] = (df['Adj. High'] - df['Adj. Close']) / df['Adj. Close']*100.0
df['PCT_change'] = (df['Adj. Close'] - df['Adj. Open']) / df['Adj. Open']*100.0

df = df[['Adj. Close','HL_PCT','PCT_change','Adj. Volume']]

forecast_col='Adj. Close'
df.fillna(-99999, inplace=True)

forecast_out=int(math.ceil(0.01*len(df)))

df['label'] = df[forecast_col].shift(-forecast_out)
df.dropna(inplace=True)

X = np.array(df.drop(['label'],1))
y=np.array(df['label'])

X = preprocessing.scale(X)

X=X[:-forecast_out+1]
df.drona(inplace=True)
y = np.array(df['label'])

print(len(X),len(y))

但显示以下错误

runfile('C:/Users/jayram/.spyder-py3/temp.py', wdir='C:/Users/jayram/.spyder-py3')

    from sklearn.leanear_model import LearnRegression

ModuleNotFoundError: No module named 'sklearn.leanear_model'

anaconda安装了所有软件包？然后为什么上面的错误显示或者我们必须在安装anaconda后安装软件包？

Answer 1

它是linear_model，而不是leanear。

http://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LinearRegression.html

此外，您的代码似乎根本不使用该模块中的类，因此您只需删除该行

在anaconda 3，spyder中没有发生名为'sklearn.leanear_model'的模块
