Can't get the FIM to work with LM Studio

[Gabriel]

Describe the bug
I've tried to use WizardCoder for FIM and it's not working, here is the log for LM Studio:

To Reproduce
start a server with any coder LLM and test, sometimes i get a completion but it's nonsense...

Expected behavior
A completion based on the context... in my case it should fill "$sedii]);" but sometimes i get nothing, other times i get some "#import <...>"

Desktop (please complete the following information):

• OS: Windows
• Version 11

Additional context
I used twinny v3.11.9
and VSCode Version: 1.88.1 (user setup)

Hello, it seems you are using WizardCoder for FIM but with codellama template. I don't know which fim template WizardCoder supports or if it supports FIM. You should try a different model. Either deepseek base or codellama-code.

https://github.com/rjmacarthy/twinny/blob/main/docs/providers.md#fim-auto-complete-2

I see here: https://huggingface.co/epinnock/wizardcoder-1b-merged#fill-in-the-middle that WizardCoder uses the same FIM template as Starcoder, please try that as the FIM template, or use custom and edit your own.

See docs for recommended settings.

thanks for the answer, I've made progress but still not good enough, at least now i can get the FIM to work, here is what i get, I will try other LLM maybe the ones i got are not good...

Hey, starcoder2 has an issue with completions, I have not been successful with it either. Please try codellama or deepseek-coder. Many thanks.
