使用 PaddleNLP 在 CPU(支持 AVX 指令)下跑通 llama2-7b 模型 🚣
PaddleNLP 在支持 AVX 指令的 CPU 上对 llama 系列模型进行了深度适配和优化，此文档用于说明在支持 AVX 指令的 CPU 上使用 PaddleNLP 进行 llama 系列模型进行高性能推理的流程。
检查硬件：
| 芯片类型 | GCC 版本 | cmake 版本 |
|---|---|---|
| Intel(R) Xeon(R) Platinum 8463B | 9.4.0 | >=3.18 |
注：如果要验证您的机器是否支持 AVX 指令，只需系统环境下输入命令，看是否有输出：
lscpu | grep -o -P '(?<!\w)(avx\w*)'# 显示如下结果 - avx avx2 **avx512f** avx512dq avx512ifma avx512cd **avx512bw** avx512vl avx_vnni **avx512_bf16** avx512vbmi avx512_vbmi2 avx512_vnni avx512_bitalg avx512_vpopcntdq **avx512_fp16**
环境准备：
1 安装 numactl
apt-get update apt-get install numactl
2 安装 paddle
2.1 源码安装：
git clone https://github.com/PaddlePaddle/Paddle.git cd Paddle && mkdir build && cd buildcmake .. -DPY_VERSION=3.8 -DWITH_GPU=OFFmake -j128 pip install -U python/dist/paddlepaddle-0.0.0-cp38-cp38-linux_x86_64.whl
2.2 pip 安装:
python -m pip install --pre paddlepaddle -i https://www.paddlepaddle.org.cn/packages/nightly/cpu/
2.3 检查是否安装正常:
python -c "import paddle; paddle.version.show()" python -c "import paddle; paddle.utils.run_check()"
3 克隆 PaddleNLP 仓库代码，并安装依赖
# PaddleNLP是基于paddlepaddle『飞桨』的自然语言处理和大语言模型(LLM)开发库，存放了基于『飞桨』框架实现的各种大模型，llama系列模型也包含其中。为了便于您更好地使用PaddleNLP，您需要clone整个仓库。 pip install --pre --upgrade paddlenlp -f https://www.paddlepaddle.org.cn/whl/paddlenlp.html
4 安装第三方库和 paddlenlp_ops
# PaddleNLP仓库内置了专用的融合算子，以便用户享受到极致压缩的推理成本 git clone https://github.com/PaddlePaddle/PaddleNLP.git cd PaddleNLP/csrc/cpu sh setup.sh
5 第三方库安装失败
#如果oneccl安装失败 建议在gcc 8.2-9.4之间重新安装 cd csrc/cpu/xFasterTransformer/3rdparty/ sh prepare_oneccl.sh#如果xFasterTransformer 安装失败,建议在gcc 9.2以上重新安装 cd csrc/cpu/xFasterTransformer/build/ make -j24#更多命令和环境变量可参考csrc/cpu/setup.sh
Cpu 高性能推理
PaddleNLP 还提供了基于 intel/xFasterTransformer 的 CPU 高性能推理，目前支持 FP16、BF16、INT8多种精度推理，以及 Prefill 基于 FP16,Decode 基于 INT8混合方式推理。
非 HBM 机器高性能推理参考：
1 确定 OMP_NUM_THREADS
OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}')
2 动态图推理
cd ../../llm/
#2.动态图推理 高性能 AVX 动态图模型推理命令参考
OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}') numactl -N 0 -m 0 python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float32 --avx_mode --avx_type "fp16_int8" --device "cpu"
3 静态图推理
#step1 : 静态图导出
python ./predict/export_model.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --output_path ./inference --dtype float32 --avx_mode --avx_type "fp16_int8" --device "cpu"
#step2: 静态图推理
OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}') numactl -N 0 -m 0 python ./predict/predictor.py --model_name_or_path ./inference --inference_model --dtype "float32" --mode "static" --device "cpu" --avx_mode
HBM 机器高性能推理参考：
1 硬件和 OMP_NUM_THREADS 确认
#理论上HBM机器比非HBM机器nexttoken时延具有1.3倍-1.9倍的加速
#确认机器具有 hbm
lscpu
#如 node2、node3表示支持 hbm
$NUMA node0 CPU(s): 0-31,64-95
$NUMA node1 CPU(s): 32-63,96-127
$NUMA node2 CPU(s):
$NUMA node3 CPU(s):#确定OMP_NUM_THREADS
lscpu | grep "Socket(s)" | awk -F ':' '{print $2}'
OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}')
2 动态图推理
cd ../../llm/
# 高性能 AVX 动态图模型推理命令参考
FIRST_TOKEN_WEIGHT_LOCATION=0 NEXT_TOKEN_WEIGHT_LOCATION=2 OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}') numactl -N 0 -m 0 python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float32 --avx_mode --avx_type "fp16_int8" --device "cpu"
注:FIRST_TOKEN_WEIGHT_LOCATION和NEXT_TOKEN_WEIGHT_LOCATION表示first_token权重放在numa0,next_token权重放在numa2(hbm缓存节点)。
3 静态图推理
# 高性能静态图模型推理命令参考
# step1 : 静态图导出
python ./predict/export_model.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --output_path ./inference --dtype float32 --avx_mode --avx_type "fp16_int8" --device "cpu"
# step2: 静态图推理
FIRST_TOKEN_WEIGHT_LOCATION=0 NEXT_TOKEN_WEIGHT_LOCATION=2 OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}') numactl -N 0 -m 0 python ./predict/predictor.py --model_name_or_path ./inference --inference_model --dtype "float32" --mode "static" --device "cpu" --avx_mode
快速实践
安装
安装库
sudo apt update
sudo apt install numactl看看cpu是否支持avx
lscpu | grep -o -P '(?<!\w)(avx\w*)'安装飞桨
pip install --pre paddlepaddle -i https://www.paddlepaddle.org.cn/packages/nightly/cpu/
验证安装好飞桨
python -c "import paddle; paddle.version.show()"
python -c "import paddle; paddle.utils.run_check()"安装PaddleNLP库
pip install --pre --upgrade paddlenlp -f https://www.paddlepaddle.org.cn/whl/paddlenlp.html下载PaddleNLP源码并
安装加速算子
git clone https://github.com/PaddlePaddle/PaddleNLP.git
cd PaddleNLP/csrc/cpu

(py312) skywalk@DESKTOP-9C5AU01:~/github/PaddleNLP/csrc/cpu$ cd xFasterTransformer/3rdparty/
(py312) skywalk@DESKTOP-9C5AU01:~/github/PaddleNLP/csrc/cpu/xFasterTransformer/3rdparty$ sh prepare_oneccl.sh还是失败，看文档说gcc版本在8-9之间比较好，而当前是13.3 ，版本有点高，就先搁置吧
现在的情况是：自己本机编译失败，星河社区github连接太慢导致编译失败，kaggle编译也失败。
再次安装加速算子
先添加Ubuntu的intel cpu库
# 下载基础工具包
wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
sudo apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
echo "deb https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list
sudo apt update# 安装完整开发套件（包含oneCCL）
sudo apt install intel-oneapi-ccl intel-oneapi-ccl-devel intel-oneapi-runtime-dnnl
再安装
cd PaddleNLP/csrc/cpu && oneCCL_DIR=/opt/intel/oneapi/ccl/latest/lib/cmake/oneCCL sh setup.sh推理
到PaddleNLP/llm 这个目录，执行：
python ./predict/predictor.py --model_name_or_path deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B --inference_model --dtype float32 --avx_mode --avx_type "fp16_int8" --device "cpu"总结
坑比预想的多，目前还没通。
调试
报错This system does not support NUMA policy
OMP_NUM_THREADS=$(lscpu | grep "Core(s) per socket" | awk -F ':' '{print $2}') numactl -N 0 -m 0 python ./predict/predictor.py --model_name_or_path meta-llama/Llama-2-7b-chat --inference_model --dtype float32 --avx_mode --avx_type "fp16_int8" --device "cpu"
numactl: This system does not support NUMA policy
那就不用numactl了
报错：ModuleNotFoundError: No module named 'paddlenlp_ops'
from paddlenlp_ops import (
ModuleNotFoundError: No module named 'paddlenlp_ops'
看来不编译 paddlenlp_ops不行啊！
在kaggle 编译paddlenlp_ops报错
cd xFasterTransformer/3rdparty/
!cd PaddleNLP/csrc/cpu/xFasterTransformer/3rdparty && sh prepare_oneccl.sh再试最后一次，不行就撤。 单独编译oneccl过了，但是再编译paddlenlp还是报错

本机编译报错

直接pip 安装试试
pip install oneccl
报错依旧
安装这个试试
sudo apt install libdnnl3尝试新的方法

sudo apt install intel-oneapi-ccl intel-oneapi-ccl-devel
本机这边非常慢，kaggle那边也不算快

kaggle那边已经装好了，现在可以编译ops了
!cd PaddleNLP/csrc/cpu && oneCCL_DIR=/opt/intel/oneapi/ccl/latest/ sh setup.sh编译的时候有这样的报错
warnings.warn(warning_message) /usr/local/lib/python3.10/dist-packages/setuptools/_distutils/cmd.py:66: SetuptoolsDeprecationWarning: setup.py install is deprecated. !!********************************************************************************Please avoid running ``setup.py`` directly.Instead, use pypa/build, pypa/installer or otherstandards-based tools.See Why you shouldn't invoke setup.py directly for details.********************************************************************************!!self.initialize_options() /usr/local/lib/python3.10/dist-packages/setuptools/_distutils/cmd.py:66: EasyInstallDeprecationWarning: easy_install command is deprecated. !!
kaggle最后这样报错/usr/bin/ld: cannot find -l:libxfastertransformer.so: No such file or directory

发现是这里：

也就是oneapi
找到原因了，原来刚才设置的路径不对
# 标准Intel oneAPI路径（Linux）
export oneCCL_DIR=/opt/intel/oneapi/ccl/latest/lib/cmake/ccl# 自定义安装路径
export oneCCL_DIR=/your/custom/path/lib/cmake/ccl# 运行CMake时注入变量
cmake -DoneCCL_DIR=$oneCCL_DIR ..
应该用这句：
!cd PaddleNLP/csrc/cpu && oneCCL_DIR=/opt/intel/oneapi/ccl/latest/lib/cmake/oneCCL sh setup.sh还是报错，应该再装这个：
sudo apt install intel-oneapi-runtime-dnnlkaggle报错：Your notebook tried to allocate more memory than is available. It has restarted.（放弃）
这个没办法了，就是超限了
kaggle放弃

暂时搁置
还可能需要的一些库：
sudo apt install libdnnl-dev
sudo apt install intel-oneapi-mkl
sudo apt install libmkl-vml-avx libmkl-dev intel-oneapi-runtime-mkl
安装intel-mkl # 数学库的时候出来提示
intel-mkl # 数学库
出来提示：
