Version issues of mmcv and mmdet

[wzhuo2022]

I noticed that the mmcv requirement in the project file is >=1.3.17, \<1.5.0. When I installed mmcv according to the official website, all versions were >=2.0.0. I searched the historical versions and could only find versions >=2.0.0. Can you provide any help? How can I find the matching version?
