Installation on python 3.6

[zenkavi]

In trying to install on python 3.6 I got the following error: The error suggests kabuki depends on an older version of openssl that is no longer supported on python 3.6 (https://docs.python.org/3/whatsnew/3.6.html). Do you have any recommendations for this?

UnsatisfiableError: The following specifications were found to be in conflict:
  - hddm -> kabuki -> python 3.3* -> openssl 1.0.1*
  - hddm -> kabuki -> python 3.3* -> xz 5.0.5
  - python 3.6*

Seems the actual problem is that it depends on Python 3.3, as binaries for 3.6 have not been built yet. You could try install via pip instead.

Neither conda nor pip worked on my system (Unix, anaconda Python 3.6). I managed to install pymc via conda and kabuki via pip, but neither works for hddm.

Here is the output of pip:

And here is the output of conda install -f -c pymc hddm:

I assumed that -f would force conda not to look for dependencies but that doesn't seem to be the case.

What error are you getting?

I updated my answer with the errors.

Actually I think the issue is that I can't run gcc from a particular node of my computing system. Installing from a different node works.

While this was just my being dumb, it could be useful for people to realize that you can mix-and-match pip and conda to install as necessary.
