I am trying to create a Docker image with graph-tool installed along with a number of geospatial C libraries with Debian stretch OS. Everything but graph-tool has been set up, and is available here ( https://hub.docker.com/r/kuanb/peartree/). The Dockerfile to create that image can be viewed here ( https://github.com/kuanb/peartree/blob/ea45bdd0a045c1bb7769f88801b5dab85c3f9... ). I attempt to install graph-tool in a container from the above image with the following: sed -i -e '$a\ deb http://downloads.skewed.de/apt/stretch stretch main\ deb-src http://downloads.skewed.de/apt/stretch stretch main' /etc/apt/sources.list && \ apt-get update && \ apt-get install python3-graph-tool This appears to be successful. I then go into a Python3 repl and attempt to import graph_tool which results in a ModuleNotFoundError. I suspect the error has to do with versions of Python3 and where the library (graph-tool) is being placed versus where pip is placing its libraries. Unfortunately, I am not entirely confident navigating this and would be appreciative of any guidance - I suspect I am "almost there" and someone on this list may be more familiar with setting this up and could point me in the right direction. Thanks in advance and happy new year. :) -- *KUAN BUTTS* kuanbutts.com
