Installation failure on Ubuntu 16.04, Python 3: Non-zero return code '1' from command

[zuoxingdong]

I am using Ubuntu 16.04 and Python 3 with Anaconda.

I am following the instruction:

$ sudo apt-get install lua5.1 liblua5.1-0-dev libffi-dev gettext \
   freeglut3-dev libsdl2-dev libosmesa6-dev python-dev python-numpy realpath

Then I run

bazel build :deepmind_lab.so --define headless=glx

which returns

INFO: Found 1 target...
Target //:deepmind_lab.so up-to-date:
  bazel-bin/deepmind_lab.so
INFO: Elapsed time: 4.238s, Critical Path: 3.06s

Then

bazel run :python_module_test --define headless=glx

but it returns errors

INFO: Found 1 target...
Target //:python_module_test up-to-date:
  bazel-bin/python_module_test
INFO: Elapsed time: 0.201s, Critical Path: 0.01s

As it says in the readme, Python 3 is not supported. You need Python 2.7.
