Python virtualenv setuptools package issue

Using virtualenv with -p python2 While installing pip install gluoncv it errors out with following error 

Requirement already satisfied: setuptools in ./mxv16_p2/lib/python2.7/site-packages (45.0.0)
ERROR: Package 'setuptools' requires a different Python: 2.7.12 not in '>=3.5'
Solution

  • Thanks to https://github.com/pypa/virtualenv/issues/1493

    Specifically this comment : https://github.com/pypa/virtualenv/issues/1493#issuecomment-576250710

    pip install --upgrade 'setuptools<45.0.0'

    It expected a lower version of setuptools and hence pip install --upgrade to lower version [i.e. downgraded]
