Support for Python 2.7

Python 2.7 is deprecated from 2020. For more information on the scientific Python ecosystem’s transition to Python3 only, see the python3-statement.

Imageio 2.6.x is the last release to support Python 2.7. This release will remain available on Pypi and conda-forge. The py2 branch may be used to continue supporting 2.7, but one should not expect (free) contributions from the imageio developers.

For more information on porting your code to run on Python 3, see the python3-howto.
