Fix NameResolutionError

✅ Solution

The "NameResolutionError" in tiktoken usually indicates your system can't resolve the OpenAI server's address due to network issues or being offline. To fix this, ensure you have a stable internet connection. If offline use is required, explore local model alternatives like those offered by Hugging Face, as tiktoken fundamentally relies on network access for tokenizer data unless you've specifically cached it beforehand and configured tiktoken to use the cached version.
