Environment

根据Triton 环境对应表，Colab 环境缺少 tensorrt-8.6.1，cudnn9-cuda-12，triton-server 版本应该选择 r23.10。
在这里插入图片描述

upgrade boost

wget https://boostorg.jfrog.io/artifactory/main/release/1.84.0/source/boost_1_84_0.tar.gz
tar -zxvf boost_1_84_0.tar.gz 
cd boost_1_84_0
chmod -R 777 .
./bootstrap.sh --with-libraries=all --with-toolset=gcc
./b2 -j20 toolset=gcc
./b2 install

install libarchive

wget https://github.com/libarchive/libarchive/releases/download/v3.6.2/libarchive-3.6.2.tar.gz
tar -zxvf libarchive-3.6.2.tar.gz 
cd libarchive-3.6.2
./configure
make
sudo make install

install tensorrt-8.6.1

# 方法一
wget https://developer.nvidia.com/downloads/compute/machine-learning/tensorrt/secure/8.6.1/tars/TensorRT-8.6.1.6.Linux.x86_64-gnu.cuda-12.0.tar.gz
tar -xvf TensorRT-8.6.1.6.Linux.x86_64-gnu.cuda-12.0.tar.gz 
sudo mv TensorRT-8.6.1.6/ /usr/local/
vim ~/.bashrc 
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/TensorRT-8.6.1.6/lib
source ~/.bashrc # 方法二
wget https://developer.nvidia.com/downloads/compute/machine-learning/tensorrt/secure/8.6.1/local_repos/nv-tensorrt-local-repo-ubuntu2204-8.6.1-cuda-12.0_1.0-1_amd64.deb
sudo cp /var/nv-tensorrt-local-repo-ubuntu2204-8.6.1-cuda-12.0/nv-tensorrt-local-42B2FC56-keyring.gpg /usr/share/keyrings/
sudo dpkg -i nv-tensorrt-local-repo-ubuntu2204-8.6.1-cuda-12.0_1.0-1_amd64.deb

Building Triton server

编译 Triton

git clone -b r23.10 https://github.com/triton-inference-server/server.git# enable-all 编译失败了，原因可能为编译某个 backend 导致的，解决方法未知
./build.py -v --no-container-build --build-dir=`pwd`/build --enable-all# 自定义参数且只编译 python 后端，成功
./build.py -v --no-container-build --build-dir=$(pwd)/build --enable-logging --enable-stats --enable-tracing --enable-gpu --endpoint http --endpoint grpc  --backend python --extra-core-cmake-arg j=0

设置软链接

ln -s /content/server/build/opt/tritonserver /opt/tritonserver

Deploying HuggingFace models

克隆 python_backend，因为我们要使用 python_backend 中的 triton_python_backend_utils

git clone https://github.com/triton-inference-server/python_backend.git -b r23.02
cd python_backend

配置模型库
部署非常能打的文生图大模型 playground-v2.5

mkdir -p models/playground-v2.5/1/
# 配置文件
touch models/playground-v2.5/config.pbtxt
# 模型文件
touch models/playground-v2.5/1/model.py
# 客户端文件
touch models/playground-v2.5/client.py

config.pbtxt

]
