[BUG] {python3 install_requirements.py failing}

[dmorris0]

I have a RPi 4 with Ubuntu Jammy 22.04 and an Oak-D Lite connected through the USB 3 connector. I cloned the depthai github repo and am stepping through the installation. Everything seems to work until I get to the install_requirements.py line:

ubuntu@tbot:~/depthai$ python3 install_requirements.py

I'm not sure what to expect, but this isn't correct. Any advice one what to do?

When you see this failing - do you still have an Internet connection, can access other online resources? Seems a network connection could not be established anylonger.

Could it be a power-supply issue (while installing the SoC is heating up, a lot of processing power required), or simply a loose connection?

[dmorris0]

Interesting. I turned it off and let it cool down. Then restarted and then it installed fine. Not sure if it is a loose connection or over power issue. I have a feeling whatever the problem is that it will resurface.

[dmorris0]

There seems to be some connection problem, although now with the USB. When I run the first demo, it initially works (I see the depth and color images), and then after a couple seconds it fails:

Is your HW operating under rough conditions like heat, vibrations? Do you run your "RPi 4" with a battery, would you have a chance to use another power-supply? Could it be maybe a broken "RPi 4"?

Can you run any other heavy job on the system like compressing&decompressing (ZIP?, tar& ), or video-transcoding (VLC? gstreamer?) to see if your HW is "stable under heavy load"?

[dmorris0]

It is using a battery, but no harsh conditions. I might be able to try a different power supply. I could also try some heavy jobs, although not sure how to measure stability.

[brmarkus]

There could be peaks in energy consumption which the battery temporarily could not provide. A bigger power-supply (or additional battery/batteries in parallel to the first) might help...

Compress a big file (e.g. video-file) and create a SHA checksum - and compare with the checksum of the same file, but calculated on a different machine.

Transcode a video-file - a visual inspection might not reveal optical artifacts - but maybe the transcoding will generate error-/warning-messages.

Sorry if all this leads to nothing... energy consumption (or heat?, or loose connection?) is just a guess...
