boto3: Boto3 incompatible with python zip import

One of Python’s useful features is its ability to load modules from a .zip archive (PEP here), allowing you to package up multiple dependencies into a single file.

Boto breaks when trying to import it from a .zip, throwing:

  File "C:\code sandbox\boto.zip\boto3\session.py", line 263, in client
  File "C:\code sandbox\boto.zip\botocore\session.py", line 799, in create_client
  File "C:\code sandbox\boto.zip\botocore\session.py", line 668, in _get_internal_component
  File "C:\code sandbox\boto.zip\botocore\session.py", line 870, in get_component
  File "C:\code sandbox\boto.zip\botocore\session.py", line 150, in create_default_resolver
  File "C:\code sandbox\boto.zip\botocore\loaders.py", line 132, in _wrapper
  File "C:\code sandbox\boto.zip\botocore\loaders.py", line 424, in load_data
botocore.exceptions.DataNotFoundError: Unable to load data for: endpoints

How to Reproduce:

1. Create a .zip containing boto3 and botocore
2. Create a .py file in the same directory as the zip (access keys removed for obvious reasons):

sys.path.insert(0, 'boto.zip')
import boto3

s3 = boto3.client('s3', aws_access_key_id='access_key', aws_secret_access_key='secret_key')

1. Run
