with open('README.md', encoding='utf-8') as f:
TypeError: 'encoding' is an invalid keyword argument for this function

Steps to reproduce

pip install superset --upgrade

I see that setup.py was just updated to include this encoding code - did that change the requirements to install/update setup from 2.7 to 3.x?

Also tried running
wget https://raw.githubusercontent.com/apache/incubator-superset/master/requirements.txt
pip install -r requirements.txt

It seems that the newest distribution 0.26.1 ist not available at PyPI.

pip list --outdated --trusted-host pypi.python.org
==>
superset 0.25.6 0.26.0 sdist

0.26.2 is working. thx
