Requirements

• Python >= 3.6(Conda)
• PyTorch 1.3
• torchvision that matches the PyTorch installation.
  You can install them together at pytorch.org to make sure of this.
• OpenCV, needed by demo and visualization
• fvcore: pip install git+https://github.com/facebookresearch/fvcore
• pycocotools: pip install cython; pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI
• VS2019(no test in older version)/CUDA10.1(no test in older version)

several files must be changed by manually.

file1: 
  {your evn path}\Lib\site-packages\torch\include\torch\csrc\jit\argument_spec.h
  example:
  {C:\Miniconda3\envs\py36}\Lib\site-packages\torch\include\torch\csrc\jit\argument_spec.h(190)
    static constexpr size_t DEPTH_LIMIT = 128;
      change to -->
    static const size_t DEPTH_LIMIT = 128;
file2: 
  {your evn path}\Lib\site-packages\torch\include\pybind11\cast.h
  example:
  {C:\Miniconda3\envs\py36}\Lib\site-packages\torch\include\pybind11\cast.h(1449)
    explicit operator type&() { return *(this->value); }
      change to -->
    explicit operator type&() { return *((type*)this->value); }

Build detectron2

After having the above dependencies, run:

conda activate {your env}

"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvars64.bat"

git clone https://github.com/conansherry/detectron2

cd detectron2

python setup.py build develop

Note: you may need to rebuild detectron2 after reinstalling a different build of PyTorch.

Detectron2 is Facebook AI Research's next generation software system
that implements state-of-the-art object detection algorithms.
It is a ground-up rewrite of the previous version,
Detectron,
and it originates from maskrcnn-benchmark.

What's New

• It is powered by the PyTorch deep learning framework.
• Includes more features such as panoptic segmentation, densepose, Cascade R-CNN, rotated bounding boxes, etc.
• Can be used as a library to support different projects on top of it.
  We'll open source more research projects in this way.
• It trains much faster.

See our blog post
to see more demos and learn about detectron2.

Installation

See INSTALL.md.

Quick Start

See GETTING_STARTED.md,
or the Colab Notebook.

Learn more at our documentation.
And see projects/ for some projects that are built on top of detectron2.

Model Zoo and Baselines

We provide a large set of baseline results and trained models available for download in the Detectron2 Model Zoo.

License
