 Note that running waifu2x in without [JIT caching](https://devblogs.nvidia.com/parallelforall/cuda-pro-tip-understand-fat-binaries-jit-caching/) is very slow, which is what would happen if you use docker.
 For a workaround, you can mount a host volume to the `CUDA_CACHE_PATH`, for instance,
 
 ```
-nvidia-docker run -v $PWD/ComputeCache:/root/.nv/ComputeCache waifu2x th waifu2x.lua --help
+docker run --gpus all -v $PWD/ComputeCache:/root/.nv/ComputeCache waifu2x th waifu2x.lua --help
