Some version to python3.6? #468

Closed francisrod01 closed 5 years ago

francisrod01 commented 6 years ago

Some version to python3.6? I think that this code is to python2.7...

Im not entirely sure what the issue is but MAVProxy currently does not run under python 3 if that is what you are attempting to do. See https://github.com/ArduPilot/MAVProxy/pull/420

francisrod01 commented 6 years ago

Thanks, @SamuelDudley! That is the point!

I'll follow the issue about it.

francisrod01 commented 6 years ago

@SamuelDudley after the rebase, I try to upgrade mavproxy as pip3 in my hasperryPI VirtualMachine in VMBox and it's fail.

SamuelDudley commented 6 years ago

Can't say I'm using pip to test my branches sorry. The stack trace looks like it's failing during the pymavlink mavnative build process. Not being able to find python.h usually means you haven't installed the python-dev packages or they can't be found...

francisrod01 commented 6 years ago

Thanks, it works! But now using pip3 to install mavproxy I see that error `

Successfully installed mavproxy-1.6.2

$ mavproxy.py --master tcp:127.0.0.1:5760 --out udp:127.0.0.1:14551 --out udp:10.55.222.120:14556

This package in pip3 is it outdated?

Sorry about some questions, but I did not want to have to clone repository and install global on system.

Thank you for understand! :)

SamuelDudley commented 6 years ago

Hi, The problem is that MAVProxy doesn't run under python3 and you are trying to install the unmodified version from pip. You need to use my git branch which has the required changes to run with python3. I haven't used pip this way but a quick google turns up this result https://stackoverflow.com/questions/20101834/pip-install-from-git-repo-branch

francisrod01 commented 6 years ago

Thank you @SamuelDudley , installing remotely it new to me!

It running with pip3 install ~/MAVProxy local or git+https://github.com/SamuelDudley/MAVProxy@wx_phoenix_wip_rebase.

Well, in my first test, it was necessary to install numpy dependency of MAVProxy.

I haven't found terrain and adsb compatibles dependencies to use with MAVProxy package.

I received the output before my first test with dronekit copter example:

So.. some errors but it works!! :1st_place_medal:

SamuelDudley commented 6 years ago

Working backwards the errors you are seeing are: a pymavlink issue https://github.com/ArduPilot/MAVProxy/issues/467 try updating pymavlink to the very latest release. The other two are both due to opencv python bindings that you don't have installed.

SamuelDudley commented 6 years ago

I'm building my python bindings from source, so if you wanted to go down that route this may help: https://www.pyimagesearch.com/2017/09/04/raspbian-stretch-install-opencv-3-python-on-your-raspberry-pi/

otherwise you could try the unnoficial python bindings in pip pip3 install opencv-python : https://pypi.python.org/pypi/opencv-python

francisrod01 commented 6 years ago

Thanks! Some errors are solved but I received others.

I installed future, xml, opencv-python and upgrade pymavlink dependencies but I still receive some errors like this:

Should I uninstall the modemmanager from the system?

This time I'm testing with ubuntu. I was unable to install python3.6 on Raspibian because of lack of system space.

stephendade commented 6 years ago

Should I uninstall the modemmanager from the system?

Not mandatory, but it does sometimes conflict with MAVProxy when using serial ports.

The other error you're getting is due to using an old version of pymavlink - you'll need to upgrade to the latest version (2.2.7). Use pip install --user --upgrade pymavlink

francisrod01 commented 6 years ago

I'm using a virtualenv, so.. --user not available here.

francisrod01 commented 6 years ago

I think that it's not prepare to run in python3.+ as a pip3 command. Some dependencies aren't resolve yet.

francisrod01 commented 6 years ago

I'm expecting to use this version of the ArduPilot using MAVProxy with Python 3.6.x but until now this is not official, right?

can't running python3.6 ? how to handle it? image

Try the latest version, it should now support python 3

amilcarlucas commented 5 years ago

Works in the latest release. Closing it now. Please reopen if the problem persists in the latest release.
