Problem with Movidius neural compute stick

idata — Tue, 20 Mar 2018 03:34:02 GMT

Hello,

I have a problem with my neural compute stick. I want to exposed these drive to others students so they can buy these but unfortunately my demonstration doesn’t work.

Can you help me please ?

I have a Mac (Apple) and I work with ubuntu. I would like to present a ncappzoo app (stream_infer) but when I write : make run in the terminal. I see : “make : *** [run] Erreur 1

What can I do ?

I really need these program for tomorrow.

Thank you for your help !

Hello, @DavidD

calm down please.

In today's question the information is too small for anyone to answer.

I do not know if you write environment information and error messages, reproduction procedure in detail.

More error messages should be displayed.

And, are you using virtualbox?

No i didn’t use virtual box I use a part of my flash drive.

@DavidD Are you using some virtual machine software (like Parallels, VirtualBox, etc.) to run Ubuntu on your Mac? Are you trying to run this natively in a Mac? If you are using a VM, make sure you've set up the appropriate USB filters (also make sure the vm is shut off before setting usb filters). More information on setting up the NCSDK and NCS on a VM can be found at https://movidius.github.io/ncsdk/VirtualMachineConfig.html. General installation instructions can be found at https://movidius.github.io/ncsdk/install.html.

I use Parallels (13) but I don't know how to set up USB filters… Thank you !

@DavidD Please visit https://movidius.github.io/ncsdk/VirtualMachineConfig.html for more information on how to set up USB filters. For Parallels, you may have to go to your external devices sub menu under devices and choose the USB device from there.

I am getting extremely frustrated with the USB recognition problem. I am running Vbox 5.2.8 on MacOS High Sierra, Ubuntu 16.04 LTS. I did install the USB filters as indicated. When I do an lsusb I see the dev id "03e7". I did install box guest additions successfully. Still, as soon as I start running make examples, I always get [Error 7] Toolkit Error: USB Failure. Code: Error opening device.

@aerdengiz @Tome_at_Intel

I do not know if it is useful, but try it.

At host OS.

$ sudo apt-get install virtualbox

$ sudo gpasswd -a USERNAME vboxusers

$ sudo reboot

and, it is recommended to enter only "name" and "vendor ID" for the USB filter.

It is recommended to leave the product ID, revision, manufacturer, product name, serial number, port blank.

Although the quotation origin is an article in Japanese, I hope it will be helpful.

Thank you, but before I try this, I wanted to make sure I understand:

by host OS you do mean MacOS, correct?

I would run these instructions in a terminal window on my Mac.

Is this not going to cause confusion as I already have vbox installed through the standard installation process?

As for the USB filters all I entered is indeed just a name (USB2 filter, USB3 filter) and the device ids. The rest is blank.

@aerdengiz

Thank you for confirming.

Yes, Host OS refers to Mac.

Is this not going to cause confusion as I already have vbox installed through the standard installation process?

The fact that the standard installation process does not work on Mac is shared among Japanese engineers.

The linked article written in the reference is mixed with the case of Windows HOST and Mac HOST.

By the way, it is also known that the movement of USB of VirtualBox was unstable long ago.

As for the USB filters all I entered is indeed just a name (USB2 filter, USB3 filter) and the device ids. The rest is blank.

Thank you. I understood the situation.

Probably it seems that setting privileges to "vboxusers" is important.

Or, trying out a self-powered USB hub may be worth a little bit.

If it does not work it will be the problem I face for the first time.

Sorry if I can not help you.

@aerdengiz Have you tried hiking1's solution listed at https://ncsforum.movidius.com/discussion/comment/1453/#Comment_1453?

OK, thank you! Yes, that worked, albeit in a slightly different way. I had to install two filters, first one as Movidius VSC Loopback Device [0100] and the second one as Movidius Ltd. Movidius MA2X5X [ 0001]. After setting this up and rebooting the whole system at first it did not work and gave the same [Error 7]. Then I physically removed the Movidius Stick and re-plugged it, and re-run $ make examples, everything worked. Note that the filter id is 03e7 for both filters. And the USB mode is 3.0 for both.

As to Pinto's suggestion, I couldn't test it. apt-get doesn't work on MacOS, one has to install Homebrew and run brew…but in fact I had removed home-brew a few months ago because I didn't like the way it interfered with my python devkit
