install failed

[yejing0]

my version are:
torch 1.10.0
torchaudio 0.10.0
torchvision 0.11.0

but this error:

Traceback (most recent call last):

The install instructions in https://github.com/MasterBin-IIAU/Unicorn/blob/master/assets/install.md don't specify a mmdet version, so it installs the latest version (I got 3+), which is incompatible with mmcv==1.4.6. Specifying a lower mmdet version (e.g. mmdet==2.25.0) seems to solve this issue.
