llama.cpp : インストール2024/02/22

	Meta の Llama (Large Language Model Meta AI) モデルのインターフェースである [llama.cpp] をインストールします。
[1]	こちらを参考に CUDA をインストールしておきます。
[2]	その他必要なパッケージをインストールしておきます。

root@dlp:~#

apt -y install nvidia-cudnn gcc g++ cmake ccache python3-numpy curl git jq

[3]	[llama-cpp] をビルドします。

debian@dlp:~$

GGML 形式のモデルをダウンロードして GGUF 形式に変換し、[llama-cpp] を起動します。
モデルは下記サイトからダウンロードできます。当例では [llama-2-13b-chat.ggmlv3.q8_0.bin] を使用します。
