Exeception Details

System.TypeInitializationException
  HResult=0x80131534
  Message=The type initializer for 'LLama.Native.NativeApi' threw an exception.
  Source=LLamaSharp
  StackTrace:
   at LLama.Native.NativeApi.llama_max_devices()
   at LLama.Abstractions.TensorSplitsCollection..ctor()
   at LLama.Common.ModelParams..ctor(String modelPath)
   at Relate.Program.<Main>d__0.MoveNext() in C:\Users\jpfau\source\repos\Relate\Relate\Program.cs:line 19

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
RuntimeError: The native library cannot be correctly loaded. It could be one of the following reasons: 
1. No LLamaSharp backend was installed. Please search LLamaSharp.Backend and install one of them. 
2. You are using a device with only CPU but installed cuda backend. Please install cpu backend instead. 
3. One of the dependency of the native library is missed. Please use `ldd` on linux, `dumpbin` on windows and `otool`to check if all the dependency of the native library is satisfied. Generally you could find the libraries under your output folder.
4. Try to compile llama.cpp yourself to generate a libllama library, then use `LLama.Native.NativeLibraryConfig.WithLibrary` to specify it at the very beginning of your code. For more informations about compilation, please refer to LLamaSharp repo on github.

Have you installed any backend packages of LLamaSharp? As you can see here.

[altxxr0]

Yes, Every backend is installed, because without most of the backends it would error that you din''t install the correct backend

Is the current released Nuget Packages not functioning?

[AsakusaRinne]

Could you please take a look at your output folder? For example, bin/debug/net6/. If there's a folder named runtimes, please check if there are dll files named llama.dll in its subfolders.

[altxxr0]

No There is no runtime folder only the native library of llama.dll

[AsakusaRinne]

Please add the following code to the very beginning of your program first.

NativeLibraryConfig.Instance.WithLibrary("<path>");

<path> is the path to a llama.dll, which you can choose one from the dlls shown above. If you don't know which to choose, please download this llama.dll, and this llava_shared.dll if you want to use LLaVA. This might be a quick fix for your problem.

However, that's a bit weird to have llama.dll but without the runtimes folder, might be a BUG here. Could you please tell me more information to further dig on this issue?

1. dotnet runtime version
2. project file (.csproj)
3. your operating system info, including windows version, cpu, etc.

[altxxr0]

Yeah, I'l tests it.

[altxxr0]

.NET Runtime is 8.0.204

[altxxr0]

Also

Severity    Code    Description Project File    Line    Suppression State
Error   CS1061  'NativeLibraryConfig' does not contain a definition for 'WithLibrary' and no accessible extension method 'WithLibrary' accepting a first argument of type 'NativeLibraryConfig' could be found (are you missing a using directive or an assembly reference?)    Relate  C:\Users\jpfau\source\repos\Relate\Relate\Program.cs    16  Active

[AsakusaRinne]

Please use WithLibrary(filename, null) if you don't need to use the LLaVA model.

[hswlab]

It seems, that the llava_shared,dll library only exists in the avx folders of deps.zip Is it currently only possible to use llava for avx backends?

[SignalRT]

It should be also in the root folder:
