OpenVINO on RPi4 Update

Posted by ralphjy Top Member May 30, 2020
Just a quick update.   I found the problem .  It was not an installation issue per se, but a model mismatch issue.  A problem with pre-compiled model versions and OpenVINO versions.  It is documented here: https://github.com/openvinotoolkit/openvino/issues/411 .  Unless I want to start building my own OpenVINO versions I guess I'll just have to wait until someone fixes it.   The workaround is to revert to earlier models and everything works as expected -> can u ...

Install OpenVINO on RPi4

Posted by ralphjy Top Member May 30, 2020
I'm getting an Intel Movidius NCS 2 Neural Compute Stick next week and I want to try using it with my RPi4 2GB, so I'm going to need to install the OpenVINO toolkit, the Model Optimizer and the Open Models Zoo repository.  I'm anticipating an arduous process.  I've used the first version of the NCS with a PYNQ-Z2 and an Ultra96 but haven't tried it with an RPi yet.  The installation of the NCSDK is pretty painless but the NCS 2 requires OpenVINO which appears to have a more comple ...
After she retired my wife got serious about sewing as a hobby.  For Christmas 2018 I got her an Echo Look from Amazon so that she could document and share her projects online.  A lot of people had concerns about the use of this device - it was intended as a style consultant/advisor but for my wife's purposes it worked great as a hands free camera and it provided the standard Alexa capabilities.     Recently got an email from Amazon that indicated that the device would stop ...
I recently received an email from Seeed Studio about a Kickstarter campaign that they're running for MARK (Make a Robot Kit).  The kit is targeted at teaching robotics in STEM education but it looks like it would also be a fun toy.  I've had bad experiences with Kickstarter before, but I've used a lot of product successfully from Seeed Studio.  The product is developed by TinkerGen which is Seeed's spinoff STEM Education company.  The kit uses the Kendryte K210 RISCV64 dual c ...
About a month ago I encountered a broken VL6180X TOF sensor board that I was trying to use for my laser focusing project Laser Focus Assembly Completed.   The sensor wasn't even responding to I2C address queries which prompted me seek some help from the community Any known I2C issues with VL6180X TOF sensor.  lui_gough suggested that it was likely to be in the level translators for the SCL and SDA signals.  The sensor itself runs on 2.8V from a local regulator but the I2C pins ca ...
I saw an interesting project on Hackster ultra96-skin-cancer-ai that uses the NCS with PYNQ on the Ultra96.  I had just finished installing the NCS on the PYNQ-Z2 board Intel Movidius NCS on PYNQ-Z2 and it would be useful to also use it with the Ultra96.  Since I'm using PYNQ V2.5 on both boards I expected that this would be straightforward since this is basically just an install of the NCS SDK.  I followed the same steps that I did with the PYNQ-Z2 getting all the necessary files ...
