https://gitee.com/mindspore/mindspore/blob/master/model_zoo/official/cv/xception/scripts/run_standalone_train.sh

It's on it mindspore Of model-zoo Medium xception Script address , Linked files 17、23 That's ok , I think it's redundant , Set up here device-id In fact, the serial number of the card used cannot be controlled , Basically , It is not used in the training code device-id This parameter . Want to know if there is a problem of redundant sentences here ？

The original intention here should be to specify the card number , Carry out a single P Training .
