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

# 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'
