Ошибка FileNotFoundError в Jupyter

Question

скопировал код из книги по машинному обучению, но когда пытаюсь обратиться к набору данных, то выходит ошибка, что файл не найден. Функция для скачивания набора данных:

 import os
  import tarfile
from six.moves import urllib
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):
    if not os.path.isdir(housing_path):
        os.makedirs(housing_path)
    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()

Функция для загрузки данных

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

Попытка показать первые 5 рядов данных:

housing = load_housing_data()

housing.head()

Выходит ошибка:

FileNotFoundError                         Traceback (most recent call last)
<ipython-input-18-01b6b4e3c8b2> in <module>
----> 1 housing = load_housing_data()
      2 
      3 housing.head()

<ipython-input-17-d307253a638f> in load_housing_data(housing_path)
      3 def load_housing_data(housing_path = HOUSING_PATH):
      4     csv_path = os.path.join(housing_path, "housing.csv")
----> 5     return pd.read_csv(csv_path)

Answer 1

pd.read_csv() умеет парсить данные по URL:

from urllib.parse import urljoin

url = urljoin(DOWNLOAD_ROOT, "datasets/housing/housing.csv")

df = pd.read_csv(url)

результат:

In [104]: df
Out[104]:
