ENCODER = tiktoken.encoding_for_model(model_name) tiktoken openai？

[kyre-99]

Actually, I want to try the local HF model, but according to the sample code, an error will be reported
('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer')) I looked carefully,
def encode_string_by_tiktoken(content: str, model_name: str = "gpt-4o"):
global ENCODER
if ENCODER is None:
ENCODER = tiktoken.encoding_for_model(model_name)
Will chunking call openai? this make me confused,can you tell me why? and how to use local-noly models? thank you
