EDVR Python部署示例

在部署前,需确认以下两个步骤

本目录下提供infer.py快速完成EDVR在CPU/GPU以及GPU上通过TensorRT加速部署的示例。执行如下脚本即可完成

#下载部署示例代码
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd FastDeploy/examples/vision/sr/edvr/python

# 下载VSR模型文件和测试视频
wget https://bj.bcebos.com/paddlehub/fastdeploy/EDVR_M_wo_tsa_SRx4.tar
tar -xvf EDVR_M_wo_tsa_SRx4.tar
wget https://bj.bcebos.com/paddlehub/fastdeploy/vsr_src.mp4
# CPU推理
python infer.py --model EDVR_M_wo_tsa_SRx4 --video vsr_src.mp4 --frame_num 5 --device cpu
# GPU推理
python infer.py --model EDVR_M_wo_tsa_SRx4 --video vsr_src.mp4 --frame_num 5 --device gpu
# GPU上使用TensorRT推理 注意TensorRT推理第一次运行有序列化模型的操作有一定耗时需要耐心等待
python infer.py --model EDVR_M_wo_tsa_SRx4 --video vsr_src.mp4 --frame_num 5 --device gpu --use_trt True

EDVR Python接口

fd.vision.sr.EDVR(model_file, params_file, runtime_option=None, model_format=ModelFormat.PADDLE)

EDVR模型加载和初始化其中model_file和params_file为训练模型导出的Paddle inference文件具体请参考其文档说明模型导出

参数

  • model_file(str): 模型文件路径
  • params_file(str): 参数文件路径
  • runtime_option(RuntimeOption): 后端推理配置默认为None即采用默认配置
  • model_format(ModelFormat): 模型格式默认为Paddle格式

predict函数

EDVR.predict(frames)

模型预测结口,输入图像直接输出检测结果。

参数

  • frames(list[np.ndarray]): 输入数据注意需为HWCBGR格式, frames为视频帧序列

返回 list[np.ndarray] 为超分后的视频帧序列
