import MultiNEAT errors

[langongjin]

hi,

I run

export MN_BUILD=boost
python setup.py build_ext
python setup.py install

then I got the following, I think it is installed successfully.

multineat 0.5 is already the active version in easy-install.pth
Installed /Library/Python/2.7/site-packages/multineat-0.5-py2.7-macosx-10.14-intel.egg
Processing dependencies for multineat==0.5
Finished processing dependencies for multineat==0.5

But when I run import MultiNEAT in Terminal to test. I got the following

  File "build/bdist.macosx-10.14-intel/egg/MultiNEAT/__init__.py", line 4, in <module>
ImportError: No module named viz```

Can you give me a hand? Thanks a lot!
