SSL error on running fetch_housing_data()

SSL error on running fetch_housing_data()

[ageron]

Hi Aishni,

I believe this bug is due to the fact that Python 3.6 on MacOSX has no certificates at all (see the release notes), so it cannot verify the SSL certificate from GitHub's servers when trying to download housing.tgz. See the second answer to this StackOverflow question for details. The solution is to:

• read /Applications/Python 3.6/ReadMe.rtf
• the ReadMe will have you run /Applications/Python 3.6/Install Certificates.command which installs the certificates.

Alternatively, you can work around the issue by downloading the file yourself and placing it in the housing directory, then comment out the urlretrieve() line in the code, and run it again.

Hope this helps,
Aurélien

For Mac OS X

1. Update to Python 3.6.5 using the native app installer downloaded from the official Python language website https://www.python.org/downloads/

I've found that the installer is taking care of updating the links and symlinks for the new Python a lot better than homebrew.

2. Install a new certificate using "./Install Certificates.command" which is in the refreshed Python 3.6 directory

   cd "/Applications/Python 3.6/"
   sudo "./Install Certificates.command"

Hi Aishni,

Did my answer solve your problem? May I close this issue?

Cheers,

Perfect, thanks for your feedback. :)

Thanks the solution worked .

read /Applications/Python 3.6/ReadMe.rtf
the ReadMe will have you run /Applications/Python 3.6/Install Certificates.command which installs the certificates.

Hi @Sunil1997 ,
These are just warnings, not errors, you can ignore them for now. I will update the notebooks to use Keras' functionality for loading MNIST, because TensorFlow's functionality has been deprecated and is printing all these warnings. However, the code still works for now, so you can just ignore these warnings.

i am run the following on red hat Linux

In [12]: from keras.applications import VGG16                                   
In [13]: from keras import backend as K

Hi @jemberie ,

This code does not look like it comes from the book or from this repository. It looks like you're getting a timeout while downloading VGG16. Check your internet connection? Try from another computer? If nothing works, please ask on StackOverflow instead.

This fixes it too -- added the ssl context workaround

import os
import tarfile
import urllib
import ssl

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")
    context = ssl._create_unverified_context()
    response = urllib.request.urlopen(housing_url, context=context)
    with open(tgz_path, 'wb') as f:
        f.write(response.read())
    housing_tgz = tarfile.open(tgz_path)
    housing_tgz.extractall(path=housing_path)
    housing_tgz.close()

Hi,
For python 3.9 and above, just go to Applications -> Python x.x -> there will be a .command file to install certificates, just click on that and you're done.
