MAVProxy failing to load wp and other modules

[Bryan Field-Elliot]

MAVProxy can't seem to load three modules upon startup:

Failed to load module: No module named wp

Failed to load module: No module named rally

Failed to load module: No module named fence

I tried this in three different ways:

1. Install MAVProxy via "pip" on OSX

2. Install MAVProxy via "pip" on Ubuntu

3. Download MAVProxy 1.3.5 tarball onto OSX. Uncomment the line after "allow running without installing". And ran it "locally" (without installing).

In all cases - the above three modules don't load.

Is there something wrong with the current distribution?

Hi Bryan,

Do any modules load?

Those ones appear at first glance to be the only default ones that
need direct access to pymavlink. It should have been pulled down as a
dependency of MAVProxy but maybe that's broken. Open a Python shell
and try "import pymavlink".

Certainly if you're downloading the tarball manually you'll need
pymavlink installed manually too.

Ben.

Hi Bryan,

I found the problem.  On Ubuntu the following will fix it:

sudo apt-get install python-opencv python-serial python-pyparsing python-numpy python-wxgtk2.8

This is the complete set of projects that mavproxy uses - some of which are implicitly pulled in by other Ubuntu packages, therefore some users might already have these packages 'for free'.  Though the only package I think is absolutely required is python-serial and python-wxgtk2.8 (I could be wrong though).

On OS-X stackoverflow claims that "brew install wxmac" is the package you want to get wxgtk.  (I'll update the droneapi wiki page)

Ben to answer your other question, yes it appears to me that other modules are loading correctly:

STABILIZE> module list

STABILIZE> log: log transfer

param: parameter handling

relay: relay handling

tuneopt: tuneopt command handling

arm: arm/disarm handling

mode: mode handling

calibration: calibration handling

rc: rc command handling

auxopt: auxopt command handling

misc: misc commands

Thank you!

Ubuntu fix: Worked.  "small_demo.py" executed successfully.

OSX fix: Did not work, even though "brew install wxmac" was successful. :(  to be conquered another day (unless you have more ideas now).  I'm content to have things working in Ubuntu today.
