说明:
- 评估耗时阶段为图像输入到结果输出的完整阶段,包括了图像的预处理和后处理。
- `Intel至强6148`为服务器端CPU型号目前正在调试使用Intel MKL-DNN 进一步加速CPU预测速度。
- `Intel至强6148`为服务器端CPU型号测试中使用Intel MKL-DNN 加速CPU预测速度使用该操作需要
- 更新到飞桨latest版本https://www.paddlepaddle.org.cn/documentation/docs/zh/install/Tables.html#whl-dev 请根据自己环境的CUDA版本和Python版本选择相应的mkl版wheel包CUDA10、Python3.7环境,应操作:
```shell
# 获取安装包
wget https://paddle-wheel.bj.bcebos.com/0.0.0-gpu-cuda10-cudnn7-mkl/paddlepaddle_gpu-0.0.0-cp37-cp37m-linux_x86_64.whl
# 安装
pip3.7 install paddlepaddle_gpu-0.0.0-cp37-cp37m-linux_x86_64.whl
```
- 预测时使用参数打开加速开关: `--enable_mkldnn True`
- `骁龙855`为移动端处理平台型号。
