Failure Information (for bugs)

Please help provide information about the failure if this is a bug. If it is not a bug, please remove the rest of this template.

Steps to Reproduce

Please provide detailed steps for reproducing the issue. We are not sitting in front of your screen, so the more detail the better.

1. just run fastapi_server.py

Note: Many issues seem to be regarding functional or performance issues / differences with llama.cpp. In these cases we need to confirm that you're comparing against the version of llama.cpp that was built with your python package, and which parameters you're passing to the context.

Try the following:

1. git clone https://github.com/abetlen/llama-cpp-python
2. cd llama-cpp-python
3. rm -rf _skbuild/ # delete any old builds
4. python -m pip install .
5. cd ./vendor/llama.cpp
6. Follow llama.cpp's instructions to cmake llama.cpp
7. Run llama.cpp's ./main with the same arguments you previously passed to llama-cpp-python and see if you can reproduce the issue. If you can, log an issue with llama.cpp

Failure Logs

Please include any relevant log snippets or files. If it works under one configuration but not under another, please provide logs for both configurations and their corresponding outputs so it is easy to see where behavior changes.

Also, please try to avoid using screenshots if at all possible. Instead, copy/paste the console output and use Github's markdown to cleanly format your logs for easy readability.

Hey @silvacarl2 sorry about that, the command to run the server via uvicorn cli changed but I think I forgot to update it everywhere. I'll fix that.

You should be able to run the server viat uvicorn --reload --factory llama_cpp.server.app:create_app. You'll also need to set the MODEL environment variable to the path to the gguf file you plan to serve or set CONFIG_FILE if you plan to serve multiple models.

[silvacarl2]

awesome, thx, let me know when we can check it out.

[abetlen]

I updated the example, you should be able to use the command I provided in my comment to run the server, let me know if you still have any issues.

[silvacarl2]

AWESOEM THX!!!! CHECKING IT OUT!!!!!!!!!

[silvacarl2]

JUST FYI THIS IS TOTALLY AWESOME. WOW.

[abetlen]

Haha happy to hear!
