Fixes #575 - Fixed broken S3 download URLs in scripts/download.sh - Added comprehensive Python download script with progress tracking - Enhanced error handling and dataset verification - Updated README with alternative download methods and troubleshooting - Added requirements-download.txt for download dependencies Key improvements: Working URLs: Replaced broken S3 amazonaws URLs with working wikitext.smerity.com URLs Python downloader: Cross-platform solution with progress bars and error handling Dataset verification: Ensure all required files are present and valid Modular downloads: Download WikiText-103 and Freebase separately or together User experience: Clear error messages, progress tracking, automatic verification Root cause analysis: The original script used S3 URLs (https://s3.amazonaws.com/research.metamind.io/wikitext/) which are no longer accessible, causing 404 errors and missing wiki.train.tokens files. Fixed by using alternative working URLs from wikitext.smerity.com. Addresses Issue #575 where PhD student reported FileNotFoundError: '/tmp/data/wikitext-103/wiki.train.tokens' blocking research work.
