Tiktoken

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.

ConnectionResetError in tiktoken often arises from network instability or server-side issues abruptly closing the connection during data transfer. Implement retry logic with exponential backoff when calling `tiktoken.encoding_for_model` or similar functions. This allows your application to gracefully handle temporary network interruptions, increasing the likelihood of a successful connection on subsequent attempts.

MaxRetryError in tiktoken usually indicates a failed attempt to download necessary model files, often due to network connectivity issues. To fix this, ensure you have a stable internet connection during the initial use of tiktoken or when new models are required. If offline use is necessary, download the required model files beforehand using `tiktoken.get_encoding()` with a valid internet connection and then specify the local path to the model file directly when initializing the tokenizer.
