[S2T] 转静态模型遇到错误：AttributeError: checkpoint

[great-wind]

根据examples/wenetspeech/asr1/README.md说明，对asr1_chunk_conformer_u2pp_wenetspeech_ckpt_1.3.0.model.tar.gz中的模型进行转化。

步骤如下： 1.进入转化脚本所在目录：cd examples/wenetspeech/asr1/ 2.解压下载的模型文件压缩包至当前目录。 3.运行转化脚本：./local/export.sh asr1_chunk_conformer_u2pp_wenetspeech_ckpt_1.3.0.model/model.yaml asr1_chunk_conformer_u2pp_wenetspeech_ckpt_1.3.0.model/exp/chunk_conformer_u2pp/checkpoints/avg_10 ./export.ji

报错如下：
