[ejzkhan]

Hi

I am new to ML and recently bought a book and trying to understand example mention in book but getting an error.
i am using it through window pyCharm IDE
i use first

import os
import tarfile
import urllib
import urllib.request
import pandas as pd

DOWNLOAD_ROOT = "https://raw.githubusercontent.com/ageron/handson-ml2/master/"
HOUSING_PATH = os.path.join("datasets", "housing")
HOUSING_URL = DOWNLOAD_ROOT + "datasets/housing/housing.tgz"

def fetch_housing_data(housing_url=HOUSING_URL, housing_path=HOUSING_PATH):
os.makedirs(housing_path, exist_ok=True)
tgz_path = os.path.join(housing_path, "housing.tgz")
urllib.request.urlretrieve(housing_url, tgz_path)
housing_tgz = tarfile.open(tgz_path)
housing_tgz.extractall(path=housing_path)
housing_tgz.close()

then
def load_housing_data(housing_path=HOUSING_PATH):
csv_path = os.path.join(housing_path, "housing.csv")
return pd.read_csv(csv_path)

at last
housing = load_housing_data()
housing.head()

I am getting below error. i will appreciate help from anyone
