Make sure all dependencies are python3 compatible

I tried to install autogluon on Ubuntu Deep Learning Base AMI 16.04/18.04 (using the python3 version) and has the following error:
Installation command:

pip3 install --upgrade mxnet-cu100 --user
pip3 install https://autogluon.s3.amazonaws.com/dist/autogluon-0.0.1-py3-none-any.whl --user

Run command

import autogluon as ag

Error:

This error is fixed after I reinstalled pynvml:

pip3 install -U pynvml --user

[sxjscience]

Also, I've reinstalled scipy

pip3 install -U scipy --user

After that, I can import autogluon correctly.

Confirmed version that is able to run:

pynvml==8.0.3
scipy==1.3.3
