colab中运行出错FileNotFoundError: class ImageNet in mmcls/datasets/imagenet.py: [Errno 2]

%%writefile /content/mmselfsup/configs/selfsup/simclr/simclr_resnet50_lxb32-coslr-le_tinyin200.py
base = 'simclr_resnet50_8xb32-coslr-200e_in1k.py'

dataset

dataset = dict(
samples_per_gpu=32,

train = dict(
data_source=dict(
data_prefix ='data/tiny-imagenet-200/train',

)

)
改写了这一部分，但是最后用它运行时，由于继承了原配置文件，其中imagenet_simclr.py中的
dataset=dict(
type=dataset_type,
data_root=data_root,
ann_file='meta/train.txt',
data_prefix=dict(img_path='train/'),
pipeline=train_pipeline))
会报错：找不到'data/imagenet/meta/train.txt‘
