spin train.py 报错

[Delay0123456789]

问题一
根据spin readme,
运行(mmdetection) db306@db306:/media/db306/data/zxs/DAVAR-Lab-OCR-main/DAVAR-Lab-OCR-main$ cd .
(mmdetection) db306@db306:/media/db306/data/zxs/DAVAR-Lab-OCR-main/DAVAR-Lab-OCR-main$ bash ./train.sh
报错 bash: ./train.sh: 没有那个文件或目录
问题二
(mmdetection) db306@db306:/media/db306/data/zxs/DAVAR-Lab-OCR-main/DAVAR-Lab-OCR-main$ bash ./demo/text_recognition/spin/train_gaspin.sh
