Installation nvm :

# curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
...
# source ~/.profile
...
# nvm install node
...
# nvm install 24
...
# nvm use 24
Now using node v24.17.0 (npm v11.13.0)

Installation de la libnccl :

# apt install libnccl2 libnccl-dev

Installation llama.ccp :

# git clone https://github.com/ggml-org/llama.cpp.git
# cd llama.cpp
# mkdir build
# cd build
# cmake ..
# cmake --build . --config Release
# make install

Chargement des modèles :

# mkdir /models
