I have recently downloaded Jupyter Notebook into my mac but the file that I was able to open in my school windows gives me an error.
These are my libraries:
# Basic Libraries
import numpy as np
import pandas as pd
import seaborn as sb
import matplotlib.pyplot as plt # we only need pyplot
sb.set() # set the default Seaborn style for graphics
# Import essential models and functions from sklearn
from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split
from sklearn.metrics import mean_squared_error
(I believe I have downloaded all the libraries into my laptop)
This is my code:
data = pd.read_csv('train.csv')
SalePrice = pd.DataFrame(data['SalePrice'])
GrLivArea = pd.DataFrame(data['GrLivArea'])
# split for train and test
xtrain, xtest, ytrain, ytest = train_test_split(GrLivArea, SalePrice, test_size = 0.25)
linReg = LinearRegression()
linReg.fit(xtrain, ytrain)
regX = xtrain
regY = linReg.intercept_ + linReg.coef_ * xtrain
# prints coefficients
print('Intercept \t: b = ', linReg.intercept_)
print('Coefficients \t: a = ', linReg.coef_)
# plot the first graph
f = plt.figure(figsize=(16, 8))
plt.scatter(xtrain, ytrain)
plt.plot(regX, regY, 'r-', linewidth = 3)
plt.show()
# plot the second graph
trainPred = linReg.predict(xtrain)
testPred = linReg.predict(xtest)
f = plt.figure(figsize=(16, 8))
plt.scatter(xtrain, ytrain)
plt.scatter(xtrain, trainPred, color = "r")
plt.show()
And this is the error that I am getting:

Does anyone know whats wrong? I feel like I have to download more libraries into my laptop (..?) because my code works on the school computer. Please help.
