MMCV==2.1.0 is used but incompatible. Please install mmcv>=2.0.0rc4, <2.1.0.

I have encountered this problem when running inference_demo.ipynb with this line of code.

import torch
import matplotlib.pyplot as plt
from mmengine.model.utils import revert_sync_batchnorm
from mmseg.apis import init_model, inference_model, show_result_pyplot

my setup (cuda: 12.1, pytorch:2.1.0, mmseg: 1.2.2, mmcv: 2.1.0, mmengine: 0.10.3)

No, it did not work. Same happens with all the demos of MMSegmentation, but MMDet as well, and probably others.
