ImportError: cannot import name 'DistributedSampler' from 'mmcls.datasets.builder'

Hello, excuse me! I'm having this problem at runtime, but I'm almost following the steps in the readme to run the configuration, so I'd like to ask how to solve this problem?

Hello, it seems that your mmfewshot didn't install correctly. Please make sure to follow the steps below:

# install mmfewshot
pip install git+https://github.com/open-mmlab/mmfewshot.git
# or manually download the code, then
# cd mmfewshot
# pip install .

Do not use mim to install it:

mim install mmfewshot  # bugs

Feel free to ask if you still have any questions.

非常感谢你的回复！ 我是按照步骤一步一步运行的，但是到mmdet的安装时，使用

mim install mmdet==2.24.0

就会出现下面图片中的问题

所以我就只把这句换成了清华镜像 pip install mmdet==2.24.0 -i https://pypi.tuna.tsinghua.edu.cn/simple

其他的语句都是没变的，但后面还是出现了一个新问题 Traceback (most recent call last): File "train.py", line 242, in <module> main() File "train.py", line 159, in main cfg.dump(osp.join(cfg.work_dir, osp.basename(args.config))) File "/home/ubuntu/anaconda3/envs/fpd02/lib/python3.8/site-packages/mmcv/utils/config.py", line 596, in dump f.write(self.pretty_text) File "/home/ubuntu/anaconda3/envs/fpd02/lib/python3.8/site-packages/mmcv/utils/config.py", line 508, in pretty_text text, _ = FormatCode(text, style_config=yapf_style, verify=True) TypeError: FormatCode() got an unexpected keyword argument 'verify'

Please try this:

pip install yapf==0.40.1

it can solve the problem in my evironment~
