These are my public, unorganized notes on stumbling blocks I've run across setting up DeepMask / SharpMask for training: https://github.com/facebookresearch/deepmask
An alternative (non-Facebook, Python instead of Torch) open-source implementation of DeepMask was previously available here: https://github.com/abbypa/NNProject_DeepMask
Before the Facebook code was released, I started some work on Dockerizing this implementation which may also help others use it: https://github.com/ryanfb/NNProject_DeepMask/blob/docker_experimental/Dockerfile
