Install the latest mmcv with 1.12 torch version works for me, but building wheels took a very long time to finish.

Install PyTorch

!conda install pytorch=1.10.0 torchvision cudatoolkit=11.1 -c pytorch

Install MMCV

#!pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.10/index.html
!pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.12.0/index.html

Hi, PyTorch dose not provide pre-built packages for torch1.12-cu111 (https://download.pytorch.org/whl/torch_stable.html).

The recommended way to install mmcv-full is to use openmim:

pip install -U openmim
mim install mmcv-full
