無模塊名爲 'sklearn.leanear_model' 的錯誤，Spyder的

Question

我使用蟒蛇與Python 3.在Spyder的我運行下面的代碼

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)) 

但它顯示了以下錯誤

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已安裝所有軟件包？那爲什麼上面的錯誤顯示？或者我們必須在安裝anaconda之後安裝軟件包？

Answer 1

它是linear_model，不是leanear。

而且，看來你的代碼不會從該模塊使用類可言，所以你可以簡單地刪除該行
