ModuleNotFoundError: No module named 'basic_cpp'

Following the install instructions on https://mountainsort.readthedocs.io/en/latest/ and using the Ubuntu PPA, I get the following messages when running mp-list-processors:

max@retina:~/src/rSW$ mp-list-processors

Running one of the "executable processor files" listed produces the following output:

max@retina:~/src/rSW$ /opt/mountainlab/packages/pyms/basic/basic.mp
Traceback (most recent call last):

    import basic_cpp as cpp
ModuleNotFoundError: No module named 'basic_cpp'

Despite this, if I forge ahead, MountainSort appears to run and work, but I can't really be confident. mlpipeline always seems to be empty (it renders a UI but the UI doesn't contain any high-information-content items) but mountainview appears to render spikes and do things when I click buttons.

I'm running Ubuntu 17.10.

The Ubuntu ppa is for 16.04, so there is probably a missing python dependency. Would you be able to try the advanced installation, i.e., via compilation.

The alternative is to add the missing dependency by following some subset of the compilation/advanced installation instructions on the docs. That is to say, it may not be necessary to compile the C++ part.

PPA has been updated to include packages for 17.10. You might want to try them.
