cfncluster with python3

[bcthomas]

I left this as a comment on #78 and wondered if I could get some help.

I cannot get cfncluster to work with 3.5.2 (works fine with 2.7). Is this a known issue? The only requirements I see in the docs where it specifically says 2.7 is for the windows section (I'm using both os x and a modern linux). If 3.5.2 is not supported, are there plans to?

Just for reference, here is the situation (for os x)...

# pyenv version
3.5.2 (set by /Users/bct/.pyenv/version)

I have the same problem, running Python 3.5.1 with Anaconda on OS X.

You also get an error if you call cfncluster without any arguments:

snorfmac:~ snorf$ cfncluster
Traceback (most recent call last):
  File "/Users/snorf/miniconda3/bin/cfncluster", line 11, in <module>
    sys.exit(main())

Confirmed the same issue running Python 3.4.4 on Windows 7.

Updates to support Python 3 have been pushed to https://github.com/awslabs/cfncluster/tree/develop. Please clone/pull/download and test.

[snorfalorpagus]

I successfully used the develop branch to create, use and delete a cluster today on Python 3.

[bcthomas]

@dougalb Success. Tested with 3.5.2 with no problems.

#Clone repo, check out develop branch
cd cli
pip install -r requirements.txt
pip install -e .

Thanks!

I've been using this for a little while now without any problems. Running on Python 3.6 now.

It sounds like this is fixed, so resolving this ticket. Please re-open if there are still problems we missed.
