python module test fails

[ahsteven]

Following the directions after succesfully building lab I run the python module test with the following command.

bazel test //python/tests:python_module_test

and get the following error

(tf-dpmind) teves@teves:~/RL_Codes/lab$ bazel test //python/tests:python_module_test

And here is the info in the test.log file:

Hm, looks like a linker error. Are you sure you have Python 2 installed?

[ahsteven]

Well I was trying to install in a conda environment that has python 3 as the main python. I am using python 3 with tensorflow which is what I planned to use to program in deepmind lab. Do you recommend that I install natively? Or how can I install in an environment where python is referring to python 3 ?

[tkoeppe]

We only support Python 2, see #41. I think there's a pull request for Python 3 support, but we don't have anyone committed to testing and supporting Python 3 at this point.
