建议看下官方文档的说明：https://www.paddlepaddle.org.cn/documentation/docs/zh/api/paddle/device/get_device_cn.html#get-device

@ghostxsl 我使用下面的命令进行多卡训练，也会报错没有找的gpu1 python3 -m paddle.distributed.launch --gpus '0,1' tools/train.py -c configs/rec/PP-OCRv3/ch_PP-OCRv3_rec_distillation.yml -o Global.pretrained_model=ppocr_models/pretrain/ch_PP-OCRv3_rec_train/best_accuracy 那这该怎么解决，需要设置全局设备？
