Dependencies

Installation instructions

  1. Install Anaconda with Python 3.6.7
  2. conda install pytorch torchvision cudatoolkit=10.0 -c pytorch
  3. pip install tqdm
  4. Extract this codebase into a directory called compression
  5. Build the underlying C++ library (need a compiler with OpenMP support):
cd compression/ans
mkdir build
cd build
cmake ..
make
