Is this project intended for Intel-only architecture, or should/will it work on ARM?

[sevhabert]

Hi Fnoop,
ARM architecture is currently not supported by OpenVINO.

[fnoop]

Hi @SeverineH - is this by design or just not got round to it yet? Will ARM support be added in the future?

[yury-gorbachev]

Hi,
No, this will be fixed. We have a fix, but would like to do some checks on it first.
But just to make sure we are talking about same thing. It will not be possible to do inference on ARM CPU, just use ARM as a host for accelerator. There are no primitives to run on ARM itself.

[rsippl]

@yury-gorbachev, will your fix allow us to do inference with models in the Intermediate Representation on a Raspberry Pi with a Movidius Neural Compute Stick?

[r0l1]

on a Raspberry Pi with a Movidius Neural Compute Stick?

I am also interested in this feature.

@rsippl This might be also an option in the future: https://aiyprojects.withgoogle.com/edge-tpu

@yury-gorbachev Will this be available soon (before the end of 2018)?

[MohamadSaada]

@yury-gorbachev I've been following this for a month now. I am also very interested, will this be released anytime soon, thanks.

[yury-gorbachev]

Yes, it should be available before new year. I'm not able to say more exact date though, sorry guys.

[njern]

Chiming here to say that this is excellent: I'm exploring some use cases with a Raspberry Pi 3B+ as the host and would like to use an NCS2 to run inference on.

Sounds like this would make that possible (since the NCS2 requires OpenVINO rather than NCSSDK) ?

[ghost]

see NCS2 should be compatible with raspberry pi 3 B+ , then only Intel can say that AI now comes from cloud to edge..........?

[raygeeknyc]

It’s great to hear that support is in the works: I’ll work on other parts of my project and leave the NCS1 in place for now. Thanks for the transparency, it’s a big help in scheduling.

[ghost]

@raygeeknyc soo it means i purchsed NCS2, the money will not going to be wasted , support will come for raspberry pi definately ?

@kakubotics read the thread

Does this mean inference will take place on the NCS2 stick only?

[ghost]

Guys just let me know NCS2 will work with raspberry pi or not?
in future ?

NCS definitely works on Raspberry Pi (we tried without OpenVINO/DLDT). Per thread here NCS will soon work there with DLDT as well.
Theoretically NCS2 should be a similar case despite of its significant performance improvement. However I am not sure who had ever tried it on a Raspberry Pi given it was just launched less than two months ago.

[mpeniak]

Yes, it should be available before new year. I'm not able to say more exact date though, sorry guys.

Hi @yury-gorbachev, do you know if we can now use Raspberry Pi 3 B+ with NCS2 already? If not, is the estimate still no later than the end of this year please?

[blitzvb]

Cannot wait! Go NCS2 on arm!

[vikingqiao]

R5 released!!!! support raspberry pi

[iPsych]

Where?

[ghost]

What is R5?

[ghost]

guys it means now we can run NCS2 on raspberry pi? right ? please say yes

[mpeniak]

@kakubotica - yeah!

[mpeniak]

This is from the install guide:

Raspberry Pi* board with ARMv7-A CPU architecture

Raspberry pi 3b+ has v8 ARM but I hope v7 is the minimum one right?
