luarocks install loadcaffe: Error: No results matching query were found

If encountering while setting up docker:

luarocks install loadcaffe: Error: No results matching query were found

fix:
1.Install custom torch:

RUN git clone https://github.com/nagadomi/distro.git ~/torch --recursive
WORKDIR /root/torch
RUN ~/torch/install-deps
RUN ~/torch/install.sh

2.Call luarocks' loadcaffe from the custom torch & install first the image lib

# Install loadcaffe
RUN apt-get install -y libprotobuf-dev protobuf-compiler
RUN /root/torch/install/bin/luarocks install image
RUN /root/torch/install/bin/luarocks install loadcaffe
