OK, I’m stumped.
I have been using the Tello Drones all 1st semester (finally; see my prior thread with @dbaldwin , using the Raspberry Pi units. Python using Raspberry Pi--any success out there? - #3 by davidbayne)
We’re on to Aruco Markers using the instructions & videos provided by @pat.ryan; it’s great stuff but won’t install properly.
In a nutshell: We can’t run the code due to various errors with OpenCV and with droneblocksutils.
I even made new SD cards for my entire class, in hopes that it was the new PiOS which was the issue. No luck. And I’m mostly installing each element by hand, instead of letting setup.py do it for me, since that hiccups more often than not.
My steps to the install can be found at fixing flying - Google Docs
The pip packages installed are at pip - Google Docs , along with (at the bottom) a copy of the error message we’re receiving.
One of the students noticed that it may be a PATH error, because when he moves the droneblocksutils into the same folder with parts of the code it works–sometimes. But even that solution seems intermittent.
Help! I’ve spent too much time on this, and am not really any further along (though I did learn a lot about how setup.py was built, but that’s not something useful for today…)
Thanks for any help.
