Library: habitat_sim_bindings.so -- Supported Python Version: Unknown

[HighlyAuditory]

I have python2.7, python 3.5 and python 3.6 installed on my gpu laptop, ubuntu 16.04.
I tried to install api with python3.6, and ./build.sh as indicated in sim readme.
I tested the sim, it works fine.
Then I test on example/example.py, error occurs

Traceback

Please follow the building instructions in the README

Your python interpreter is version 36
Please re-build habitat sim with this version of python

I have tried to install api for 2 days. Any advice will be appreciated! Thanks!

We currently don't have a nice way to specify different versions of system python and will just generate bindings for whatever python is (which generally defaults to 2.7). We highly recommend using conda environments to fix this (things should work as expected there, and python setup.py install will work).

If you want to stick with system python, there is a work-around for using different versions of system python here: facebookresearch/habitat-sim#2

Thanks. Conda solved my problem.
