Notes

Since PyTorch 1.11.0 has been released and **we have provided the mmcv-full pre-compiled packages for it**, we no longer provide them compiled with PyTorch 1.3 & 1.4 since v1.3.17. You can find previous versions compiled with PyTorch 1.3 & 1.4 [here](https://github.com/open-mmlab/mmcv/blob/master/docs/get_started/previous_versions.md). The compatibility is still ensured in our CI, but we will discard the support of PyTorch 1.3 & 1.4 this year.
