hello,

i am trying to run this command in my m500 drone "pip3 install opencv-python" inside the provided ubuntu docker container from modal ai. i was able to simply do a pip3 install numpy and pip3 install pandas. but pip3 -v install opencv-python is becoming a very lengthy process taking almost 3 hours before failing with an error. i can understand from the debugger output that it is building the library somehow.

"ERROR: Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly"

no matter what I try it won't install. is there an easy solution to get opencv working in the docker container ? i am working with is python 3.5.2 and pip 20.3.4

i consulted this stackoverflow question for solutions

ERROR: Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly

I was trying to install OpenCV4 in a docker on jetson nano. It has jetpack 4.4 s os. The docker was successfully created and Tensorflow is running but while installing OpenCV using pip it is showing

hello everybody,

i have a m500 development drone. I am following this tutorial

How to run Ubuntu on VOXL using Docker

ModalAI technical documentation for VOXL and VOXL 2 Companion Computers for PX4 and ArduPilot Obstacle Avoidance and GPS-denied navigation, assembled in the USA

ModalAI Technical Docs (docs.modalai.com)

to have docker on my drone but i kind of want to use a more recent version of ubuntu because i want a more recent version of python to work with.

like i want to be able to install more recent versions of numpy and opencv and pandas packages and run scripts on the drone itself.

however, installing the pip version of python3 itself on roskinetic-xenial_v1_0 docker image is something of a pain itself. and in the end it doesn't work.

i was looking for a solution where i didn't have to deal with outdated distributions...

someone said they were able to do ros:noetic-robot a more recent version of python and ubuntu running but when i try to do it I get an error

here is the forum post

Out of space for docker load -i

thanks for the feedback. I just ran through and updated the docs here: https://docs.modalai.com/docker-on-voxl/ It worked using the latest platform image

@tpavlic

heyyy... i do agree that using roskinetic and xenial is kind of a dumb thing... could you help me with something ? are you using the m500 drone with voxl 1 here to do the "docker pull ros:noetic-robot" command? if you are i do get an error saying

Error: Status 410 trying to pull repository library/ros: "<html>\r\n<head><title>410 Gone</title></head>\r\n<body>\r\n<center><h1>410 Gone</h1></center>\r\n<hr><center>openresty</center>\r\n</body>\r\n</html>\r\n"

i really kind of want to use the higher versions of python and a more recent ubuntu distribution.

any tips or suggestions ?

Hello everyone,

I have a m500 drone and after a flight I would like to export all the sensor data from the drone to a json file. looking at the docs, couldn't find much help. could someone point me in the direction? I basically want to gather all the data provided by all the voxl-inspect-* commands like voxl-inspect-cpu voxl-inspect-gps etc. ideally i'd prefer python but I see some C libraries involved on this page here

@Alex-Kushleyev

I apologize for being late. I am aware of the voxl-portal for debugging purposes but no that's not what I want for now. like I want to be able to read the data frame by frame using a python script which reads from a rtsp "live" link. I think its just configuring the voxl-streamer server to something else ? idk I am lost on what to do her

two more questions

is there a way for me to also in real time read the point cloud data ? I can view one the being generated in the voxl-portal section "pointcloud" but I want to read the actual pointcloud dataset in real time so I can do some other visualizations with it.
I would love if you could let me know how i can read quaternion data in real time as well..

Thank you

Syed Omair

can someone tell me how I can stream video from a different camera than the hi res camera ? like I want to be able to see all of these

cameras

I followed steps on this site but was only able to get hires

@Dobry-Kolacz thanksss!!!

Syed Omair

@Adrian-Hidalgo thank you so much. I am sorry I saw this so late

Syed Omair

@tom hey tom. Thanks it worked. I just had to resrt TELEM1 to default settings through qgroundcontrol and then run voxl-configure-mavlink-server and reset the mavlink server to default settings and after that it connected wirelessly automatically.

But on a side note, can you also help me in pairing a taranis x7 transmitter to the m500 drone. I ordered the drone with the frsky transmitter but is it supposed to be on the drone somewhere or does it come separate like shown in the documentation??

like so https://www.youtube.com/watch?v=1IYg5mQdLVI

I am unable to find it on the drone anywhere. thank you.

Syed Omair

@tom I’ll be in touch once I get the cable and test it out

Syed Omair

@tom apologies I saw this so late.

I cannot connect to qgroundcontrol since the error started showing. it used to automatically connect but it doesn't anymore. I have the correct ip address and everything. I try to initiate a connection from qgroundcontrol but this is what i get.

also external_fc was disabled (false) so i made it true.

@tom said in px4 disconnected from uart:

Syed Omair

I have the m500 drone. I get error PX4 DISCONNECTED FROM UART. can someone help ???

Syed Omair

for anyone who has the voxl-qvio issue where it says state FAIL, just try centering (using your fingers and wiggling) the voxl board and it will work. I think it just needs to be centered.

Syed Omair

I have seen multiple posts on this forum with the same issue and tried multiple solutions but none of them seem to work

some of the things I have tried.

changing sdk versions (tldr: upgraded from 0.9.4 -> 0.9.5, it wasn't working.)
voxl upgrade guide
"connected to voxl-mavlink-server but no messages from PX4"
checked and "external_fc" is false
"Connected to voxl-mavlink-server but no messages from PX4" again
tried monitoring if mavlink is sending messages. and nothing works.
mavlink monitoring
something that is potentially interesting. this down here wasn't the case before.

below is the output to voxl-qvio-server
followed this guide.
Connect m500 to PX4
checked for loose connections. unplugged and plugged everything back in
loose connection
I want to try this solution but I can't get a wired connection to qgroundcontrol. any help with that would be appreciated
wired connection to qgc solution

Thank you for your time and help,
