Import error in python 3.4.4 - python-3.x

Question

# Load the data
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
import sklearn
oecd = pd.read_csv("oecd.csv", thousands=',')
gd_per_capita = pd.read_csv("gdp_per_capita.csv", thousands=',',delimiter='\t', encoding='latin1', na_values="n/a")
#Prepare the data
country_stats = prepare_country_stats(oecd, gdp_per_capita)
x = np.c_[country_stats["GDP per capita"]]
y = np.c[country_stats["Life satisfaction"]]
#Visualise the data
country_stats.plot(kind='scatter', x="GDP per capita", y='Life satisfaction')
plt.show()
# Select a linear model
model = sklearn.linear_model.LinearRegression()
# Train the code
model.fit(x,y)
# Make a prediction for Cyprus
x_new = [[22587]] # Cyprus GDP per capita
print(model.predict(x_new))
Whenever I try to run this code in Python 3.4.4 this throws up:
Traceback (most recent call last):

sklearn has been installed though
What is wrong?
