ERROR: No matching distribution found for detectron2==0.4

[BaiLuQiShuang]

python -m pip install detectron2==0.4 -f \ https://dl.fbaipublicfiles.com/detectron2/wheels/cu92/torch1.6/index.html

I ran the above command, but the error is as follows：

WARNING: Location ' https://dl.fbaipublicfiles.com/detectron2/wheels/cu92/torch1.6/index.html' is ignored: it is either a non-existing path or lacks a specific scheme. ERROR: Could not find a version that satisfies the requirement detectron2==0.4 (from versions: none) ERROR: No matching distribution found for detectron2==0.4

Is there any other way to install detectron2, sh pip.sh has also tried. Appreciate！
