load_demo raises urllib.error.HTTPError: HTTP Error 403: Forbidden

[amontanez24]

Environment Details

Please indicate the following details about the environment in which you found the bug:

• CTGAN version: 0.7.1
• Python version: Any
• Operating System: Any

Error Description

The load_demo function is currently broken because it points to an old S3 bucket. To fix this we should migrate the demo dataset currently at 'http://ctgan-data.s3.amazonaws.com/census.csv.gz' to the new S3 bucket and load from there instead.

Steps to reproduce

from ctgan import CTGAN
from ctgan import load_demo

real_data = load_demo()
