Installation

Requirements:

  • PyTorch 1.3 (1.4 may cause some errors.)
  • torchvision from master
  • cocoapi
  • yacs
  • matplotlib
  • GCC >= 4.9
  • OpenCV
  • CUDA >= 9.2

Option 1: Step-by-step installation

# first, make sure that your conda is setup properly with the right environment
# for that, check that `which conda`, `which pip` and `which python` points to the
# right path. From a clean conda env, this is what you need to do

conda create --name MEGA -y python=3.7
source activate MEGA

# this installs the right pip and dependencies for the fresh python
conda install ipython pip

# mega and coco api dependencies
pip install ninja yacs cython matplotlib tqdm opencv-python scipy

# follow PyTorch installation in https://pytorch.org/get-started/locally/
# we give the instructions for CUDA 10.0
conda install pytorch=1.3.0 torchvision cudatoolkit=10.0 -c pytorch

export INSTALL_DIR=$PWD

# install pycocotools
cd $INSTALL_DIR
git clone https://github.com/cocodataset/cocoapi.git
cd cocoapi/PythonAPI
python setup.py build_ext install

# install cityscapesScripts
cd $INSTALL_DIR
git clone https://github.com/mcordts/cityscapesScripts.git
cd cityscapesScripts/
python setup.py build_ext install

# install apex
cd $INSTALL_DIR
git clone https://github.com/NVIDIA/apex.git
cd apex
python setup.py install --cuda_ext --cpp_ext

# install PyTorch Detection
cd $INSTALL_DIR
git clone https://github.com/Scalsol/mega.pytorch.git
cd mega.pytorch

# the following will install the lib with
# symbolic links, so that you can modify
# the files if you want and won't need to
# re-build it
python setup.py build develop

pip install 'pillow<7.0.0'

unset INSTALL_DIR

# or if you are on macOS
# MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python setup.py build develop
