----------------------------------------

To Reproduce
pip install gpt2-client

Desktop (please complete the following information):

• OS: Windows 10, Korean locale

Additional context
Version 2.0.0 was installed after kicking out all the other higher versions with that error.
pip install --upgrade --force-reinstall gpt2-client did not bypass this.
It seems pretty much similar to #4.
