python: 3.6.0
torch: 1.7.0

the problem was shown as this:

FAILED: D:/GitHub/LocalFiles/detectron2/build/temp.win-amd64-3.6/Release/GitHub/LocalFiles/detectron2/detectron2/layers/csrc/deformable/deform_conv_cuda.obj

and the detail is this:

D:/Anaconda3/envs/mainenv/lib/site-packages/torch/include\torch/csrc/jit/ir/ir.h(1347): error: member "torch::jit::ProfileOptionalOp::Kind" may not be initialized

1 error detected in the compilation of "C:/Users/aac/AppData/Local/Temp/tmpxft_000049ec_00000000-7_deform_conv_cuda.cpp1.ii".

If some setting is not prepared? For help.

I am using a windows 10 machine with the following configuration
NVIDIA GeForce GTX 1650Ti
miniconda3
python 3.8
CUDA 11.1
PyTorch 1.8 downloaded directly & installed from PyTorch.org for CUDA-11.1
I have tried to install detectron2 based on the steps given in

https://dgmaxime.medium.com/how-to-easily-install-detectron2-on-windows-10-39186139101c

I have succesfully tested PyTorch installation however in the link given when I come to Step 5
that is

pip install -e .

My setup of detectron2 fails and gives me a huge list of errors that start with

Running setup.py develop for detectron2

.... which goes on for almost hundreds of lines. Any help will be really appreciated. Thanks
