请问为什么在训练完成后无法启动预测

[bailiancg]

在训练完成后我使用命令：python run_infer.py --param_path ./examples/cls_ernie_fc_ch_infer.json来启动预测，
但是报错缺失了文件
[Errno 2] No such file or directory: './output/cls_ernie_3.0_base_fc_ch_dy/save_checkpoints/checkpoints_step_200\infer_data_params.json'
但是在训练过程中我并没有生成这个json文件。

完整报错：
INFO: 01-19 14:36:45: params.py:43 * 13200 ./output/cls_ernie_3.0_base_fc_ch_dy/save_checkpoints/checkpoints_step_200\infer_data_params.json
