I get the error message ：'ValueError: Unknown encoding gpt2'

When I run the program using the command 'python app.py', it runs normally. However, when I package the whole program using PyInstaller, I get the error message ：'ValueError: Unknown encoding gpt2'.

By the way, I have already packaged the libraries openai, revchatgpt, and tiktoken.
