py-RFCN-priv

py-RFCN-priv is based on py-R-FCN-multiGPU, thanks for bharatsingh430's job.

Disclaimer

The official R-FCN code (written in MATLAB) is available here.

py-R-FCN is modified from the offcial R-FCN implementation and py-faster-rcnn code, and the usage is quite similar to py-faster-rcnn.

py-R-FCN-multiGPU is a modified version of py-R-FCN, the original code is available here.

py-RFCN-priv also supports soft-nms.

caffe-priv supports convolution_depthwise, roi warping, roi mask pooling, bilinear interpolation, selu.

New features

py-RFCN-priv supports:

  • Label shuffling (only single GPU training).
  • PIXEL_STD.
  • Anchors outside image (described in FPN).
  • ceil_mode in pooling layer .
  • Performing bilinear interpolation operator accoording to input blobs size.
  • 2017/07/31: support LargeMarginSoftmax and cpu forward psroipooling.
  • 2017/08/04: add Deeplab and PSPNet support.
  • 2017/08/10: add Deform psroipooling by lzx1413.
  • 2017/08/18: add ROIAlign support.
  • 2017/08/27: add Axpy layer for Senet support.
  • 2017/09/04: add Focal loss

Installation

  1. Clone the py-RFCN-priv repository

    git clone https://github.com/soeaver/py-RFCN-priv

    We'll call the directory that you cloned py-RFCN-priv into PRIV_ROOT

  2. Build the Cython modules

    cd $PRIV_ROOT/lib
make

  3. Build Caffe and pycaffe

    cd $RFCN_ROOT/caffe-priv
# Now follow the Caffe installation instructions here:
#   http://caffe.berkeleyvision.org/installation.html

# cp Makefile.config.example Makefile.config
# If you're experienced with Caffe and have all of the requirements installed
# and your Makefile.config in place, then simply do:
make all -j && make pycaffe -j

    Note: Caffe must be built with support for Python layers!

    # In your Makefile.config, make sure to have this line uncommented
WITH_PYTHON_LAYER := 1
# Unrelatedly, it's also recommended that you use CUDNN
USE_CUDNN := 1
# NCCL (https://github.com/NVIDIA/nccl) is necessary for multi-GPU training with python layer
USE_NCCL := 1

    How to install nccl

    git clone https://github.com/NVIDIA/nccl.git
cd nccl
sudo make install -j
sudo ldconfig
