litgpt chat crash at first char that differs from english encodind with error : UnicodeDecodeError:

[navr32]

Bug description

Hi ! I want just try litgpt and start to just do simple inference with doc found here.

So i start with simple chat :

litgpt chat microsoft/phi-2

And at first char not english language crash of many line with :

/litgtp/lib/python3.11/site-packages/litgpt/chat/base.py", line 120, in interact
prompt = input(">> Prompt: ")
^^^^^^^^^^^^^^^^^^^^
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc3 in position 53: invalid continuation byte

So this is the utf8 witch is bad handle in your code I think. Because i have never this error with all the python
app i work on ..pytorch..and so and so..

I have add the header for utf8 encodind to the base.py and now this work but not for all the case.;sometime
the unicodedecodeerrror come again. Perhaps you will find a better system to handle well the utf8 encodind ?
Or perhaps add the # -- coding: utf-8 -- to all your header python files ?

So to have this work about good i have add this to line 2:

# -*- coding: utf-8 -*-

Many thanks for litgpt look like very promising.

What operating system are you using?

Linux
