Gemma Is Not Supported

[zddtpy]

This is a. net 8.0 console project. When I was running it, the following error occurred,'Attempted to read or write protected memory. This is often an indication that other memory is corrupt'. Can anyone provide some help.thanks.The model used is Google's gemma-2b

Gemma is a very new model format that's not supported in LLamaSharp yet. Support was added to llama.cpp yesterday, we'll hopefully upgrade our version within a month or so :)

Hi @zddtpy, I had a similar error when I followed the steps on https://github.com/SciSharp/LLamaSharp?tab=readme-ov-file#installation

In my case the error was resolved by removing the "cuda" package and installing the "cpu" one instead.

emm.maybe i have install the "cpu",but not work

There is no special code needed in LLamaSharp for Gemma to work. You just need to recompile the Cpp code yourself and it will work (I have tested the Gemma models already).

Note that in general you can't just recompile an up-to-date version of llama.cpp and use it with LLamaSharp. llama.cpp is constantly making small breaking changes to their API, so almost every update of the binaries requires a bit of tweaking to the C# binding layer.

gemma should be supported since the last set of binary updates (0.11.x), so I'll close this issue now :)
