Windows 10 w/ VS2019 and torch cpu only

[Degot]

This way I'm able to build and instal detectron2 on Windows 10..
I use CPU only for pytorch.

conda create -n test
conda activate test
conda install pip opencv numpy scipy git curl
conda install pytorch torchvision cpuonly -c pytorch
pip install git+https://github.com/facebookresearch/fvcore
pip install cython

curl -o pycocotools-2.0.1.tar.gz https://files.pythonhosted.org/packages/5c/82/bcaf4d21d7027fe5165b88e3aef1910a36ed02c3e99d3385d1322ea0ba29/pycocotools-2.0.1.tar.gz#sha256=1c06e73a85ed9874c1174d47064524b9fb2759b95a6997437775652f20c1711f
tar -xzf pycocotools-2.0.1.tar.gz
git clone https://github.com/facebookresearch/detectron2

python
with open('./pycocotools-2.0.1/setup.py') as f:
newText=f.read().replace("extra_compile_args", "extra_compile_args={'gcc': ['/Qstd=c99']},#extra_compile_args")

with open('./pycocotools-2.0.1/setup.py', "w") as f:
f.write(newText)

with open('./detectron2/setup.py') as f:
newText=f.read().replace("BuildExtension},", "BuildExtension.with_options(use_ninja=False)},")

with open('./detectron2/setup.py', "w") as f:
f.write(newText)

with open('./detectron2/detectron2/layers/csrc/cocoeval/cocoeval.cpp') as f:
newText=f.read().replace("py::dict Accumulate(", "struct tm *localtime_r(time_t *_clock, struct tm *_result) { struct tm *p = localtime(_clock); if (p) *(_result) = *p; return p;};py::dict Accumulate(")

with open('./detectron2/detectron2/layers/csrc/cocoeval/cocoeval.cpp', "w") as f:
f.write(newText)

exit()

cd pycocotools-2.0.1
python setup.py build install

cd ..\detectron2
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvars64.bat"
set DISTUTILS_USE_SDK=1
python setup.py build develop install

Thanks for this.
There's a couple of changes for me:

1. The file vcvars64.bat was at a different location (I'm not using the Enterprise version of VS)
2. I used detectron2.__version__

thank you so much

Thanks for the script. Works like a charm on the latest commit version 0.5.
