Fix MaxRetryError

✅ Solution

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.
