# matplotlib 1.5 is one of the versions that works with Python 3.4, and it # doesn't specify the upper bound for its numpy dependency. So pip will try to # install the latest version, which doesn't work with 3.4. Putting the numpy # and the matplotlib requirements to the same requirements.txt file doesn't # work unfortunately, the latest version will still get picked up. # The lower bound is random, 1.16 is the latest version to support 3.4. numpy >=1.11,<1.17 ; python_version == '3.4' numpy >=1.17 ; python_version > '3.4'
