This is the unofficial code based on PaddlePaddle of CVPR 2019 paper:
Two-Stream Adaptive Graph Convolutional Networks for Skeleton-Based Action Recognition
2s-AGCN是发表在CVPR2019上的一篇针对ST-GCN进行改进的文章，文章提出双流自适应卷积网络，针对原始ST-GCN的缺点进行了改进。在现有的基于GCN的方法中，图的拓扑是手动设置的，并且固定在所有图层和输入样本上。另外，骨骼数据的二阶信息（骨骼的长度和方向）对于动作识别自然是更有益和更具区分性的，在当时方法中很少进行研究。因此，文章主要提出一个基于骨架节点和骨骼两种信息融合的双流网络，并在图卷积中的邻接矩阵加入自适应矩阵，大幅提升骨骼动作识别的准确率，也为后续的工作奠定了基础（后续的骨骼动作识别基本都是基于多流的网络框架）。

模型动转静
python export_model.py --save_dir ./output --model_path 'The path of model for export' --batch 10batch是在静态推理时使用的批大小，需要与infer阶段一致；
会在output文件夹生成静态模型：
|-- output |-- model.pdipaprams |-- model.pdipaprams.info |-- model.pdmodel
-
生成小数据集
模型推理时使用小数据集进行模型推理，以使用xsub的joint数据生成tiny dataset：
pyhton ./data_gen/gen_infer_sample_data.py --dataset 'xsub' --mode 'joint' --data_num 50 -
模型静态推理
安装auto_log，需要进行安装，安装方式如下：
git clone https://github.com/LDOUBLEV/AutoLog cd AutoLog/ pip3 install -r requirements.txt python3 setup.py bdist_wheel pip3 install ./dist/auto_log-1.2.0-py3-none-any.whl进行模型的静态推理
pyhton infer.py --data_file 'path to tiny data set' --label_file 'path to tiny label set' --model_file ./output/model.pdmodel --params_file ./output/model.pdiparams静态推理部分主要输出：
