We recommend using English or English & Chinese for issues so that we could have broader discussion.

可以在mmfewshot/detection/datasets/builder.py 第311行左右添加如下代码：

        # wrap two dataloaders with dataloader wrapper
        #----------20230321添加以下
        #由于会出现TypeError: __init__() got an unexpected keyword argument 'persistent_workers'
        #所以在这删掉persistent_workers关键对
        del kwargs['persistent_workers']
        # ----------20230321添加以上
        data_loader = TwoBranchDataloader(
            main_data_loader=main_data_loader,
            auxiliary_data_loader=auxiliary_data_loader,
            **kwargs)
