[guyluz11]

I am running the example project on Linux dart native.

I have just followed the instructions on the readme file

Trying examples

git clone https://github.com/lindeer/llama-cpp.git
cd llama-cpp
git submodule init --recursive
dart pub get

Just run in console:

dart --enable-experiment=native-assets run example/main.dart "/path/to/your/LLM.gguf" "your prompt"

And I got this error

$ dart --enable-experiment=native-assets run example/main.dart "/home/guyc/Downloads/Nous-Hermes-2-Mistral-7B-DPO.Q5_K_M.gguf"  "your text line1
your text line2"
