## 使用教程（复现论文）
为了方便使用者能够快速的跑通每一个模型，我们在每个模型下都提供了样例数据，并且调整了batch_size等超参以便在样例数据上更加友好的显示训练&测试日志。如果需要复现readme中的效果请按照如下表格调整batch_size等超参，并使用提供的脚本下载对应数据集以及数据预处理。
| 模型 | batch_size | thread_num | epoch_num |
| :---: | :---: | :---: | :---: |
| Word2Vec | 100 | 5 | 5 |
| GNN | 100 | 1 | 30 |
| GRU4REC | 500 | 1 | 10 |
### 数据处理
参考每个模型目录数据下载&预处理脚本。
```bash
sh data_prepare.sh
```
### 训练
```bash
cd modles/recall/gnn # 进入选定好的召回模型的目录 以gnn为例
python -m paddlerec.run -m ./config.yaml # 自定义修改超参后，指定配置文件，使用自定义配置
```
### 预测
```
# 修改对应模型的config.yaml, workspace配置为当前目录的绝对路径
# 修改对应模型的config.yaml，mode配置infer_runner
# 示例: mode: train_runner -> mode: infer_runner
# infer_runner中 class配置为 class: single_infer
# 修改phase阶段为infer的配置，参照config注释
# 修改完config.yaml后 执行:
