My version is from the dockers images that you guys have. Takin in consideration that I had to modify it to remove an error . Everything is the same except :

Clone the Detectron repository

RUN git clone https://github.com/facebookresearch/detectron /detectron
&& cd /detectron
&& git reset --hard 3c4c7f67d37eeb4ab15a87034003980a1d259c94
