Is this when using MAVProxy direct from source, or via pip or the windows setup exe?
from mavproxy.
Is there a reason not to use requirements.txt (as in pip -r requirements
)?
from mavproxy.
A requirements.txt would be a good idea!
from mavproxy.
setup.py contains this comment:
# note that we do not include all the real dependencies here (like matplotlib etc)
# as that breaks the pip install. It seems that pip is not smart enough to
# use the system versions of these dependencies, so it tries to download and install
# large numbers of modules like numpy etc which may be already installed
Then it goes on to specify:
install_requires=['pymavlink>=1.1.50',
'pyserial'],
Which, as Lorenz points out, does not include numpy (or, as the comment says, matplotlib "etc"). I'm not sure how to test that a requirements file does not pull down files it shouldn't (like the comment complains about), but the following goes some way towards testing that pip does install what it should.
- check you have python "virtualenv" and "pip" installed, with
virtualenv --help
andpip --help
. If you don't, install them. cd
into the base of your repository, then create a new virtualenv (without any site-packages, withvirtualenv .venv
(or whatever you want to call it). Might want to add .venv to your gitignore too, wouldn't want to accidentally check a whole python environment in!- activate the virtualenv with
source .venv/bin/activate
. Now, when you call python, you will be using this local 'empty' virtualenv. You can switch back to your machine's normal site python at any time with thedeactivate
command. (You can also completely remove the virtualenv from your system by deleting the .venv folder, or whatever you called it). - type
pip install -r requirements.txt
and wait for it to finish. This will pull everything in requirements.txt into the clean environment, which will need them because (by default) virtualenv created an interpreter with none of the local site-packages installed. - try to setup MavProxy in your virtualenv (e.g.
python setup.py build; python setup.py install
), then try to use it. When this doesn't work due to missing dependencies, add more lines to requirements.txt specifying the packages you need, then runpip -r requirements
again. It should be faster next time, will only download the things it doesn't already have.
This approach should result in a working virtualenv assuming two things. One; that requirements.txt explicitly includes all the required dependencies, and two; that all the non-python dependencies (libraries etc) are met. If it makes a working virtualenv, it should of course also make a working python site package if you run pip install -r requirements.txt
without an active virtualenv.
I made a branch called "requirements-txt-issue159" in my fork at https://github.com/monkeypants/MavProxy that contains the requirements.txt and .gitignore changes. I added numpy and matplotlib, but of course there will be more requirements that are not met yet. @stephendade, can you please do a pip freeze
on your system to list your packages, I'm on a new machine and haven't got a working setup at the moment. If you give me your freeze list, I'll pick through and figure out what I need to get everything working.
BTW: Starting on a fresh ubuntu 14.04 machine, I had to install sudo apt-get install libpng12-dev libfreetype6-dev
to be able to install matplotlib via pip.

pip freeze
would only yield relevant results when run inside a virtualenv, I created #160 to move the discussion of requirements.txt
and virtualenv
support there
from mavproxy.
Running it in my virtualenv would only show matplotlib, numpy and their dependencies. I asked for Steve's freeze basically as a bunch of hints to make it easier for me to build up my requirements.txt from scratch.

How are you installing opencv? I think I used the Debian/Ubuntu packages previously, but if we are going to bootstrap a clean environment it might be better to build it out?
from mavproxy.
In terms of OpenCV, according to http://tridge.github.io/MAVProxy/, use an apt-get install python-opencv
from mavproxy.
oh right, I forgot about that page. Might be good if the README linked to it :)
from mavproxy.
It will be, once #151 is merged.
