Subject Re: MXNet 1.6 as last release with Python 2 support?
Date Wed, 22 Jan 2020 06:43:47 GMT
Also, it has been reported that pip wheel installation with latest pip version 20.0.1 breaks
installation of MXNet pip wheels which have py2.py3 in the wheel name. This breaks all existing
released versions. Work around is to install the older version of pip "pip install pip==19.3.1”.
