Greptile Overview

Greptile Summary

Added GPU availability validation to three deduplication tutorial notebooks. Each tutorial now imports torch and checks torch.cuda.device_count() against the required GPU count before initializing RayClient, raising a helpful error message if insufficient GPUs are available.

Key changes:

• Introduced NUM_GPUS constant (2 for fuzzy deduplication, 4 for semantic deduplication)
• Added pre-flight GPU check to prevent runtime failures
• Improved user experience with clear error messaging
• Minor notebook metadata updates (Python version, kernel display name)

The implementation correctly prevents users from running tutorials on machines without sufficient GPU resources, though the error message has a minor grammar issue ("are lesser" should be "is less").

Confidence Score: 4/5

• This PR is safe to merge with minimal risk
• The changes add helpful validation to prevent runtime failures in tutorials. The implementation is straightforward and correctly uses torch.cuda.device_count() to check GPU availability. Only minor style issue is the grammatical error in error messages.
• No files require special attention
