I ran the example of mobilenet V1 as the following instructions:

Please help me to solve this problem. I also cannot run 'make examples' after the installation.

I found it works in NCS1 but in NCS2, the error happened.

Hi @Meow10

Thank you for reaching out! Could you please provide additional information about your setup?

• Are you using the NCSDK1 or NCSDK2? (version 1.12, 2.08 or older)
• Which branch did you clone of the ncappzoo repository? (ncsdk2 or master)
• Are you using the original Neural Compute Stick or the Neural Compute Stick 2?
• Is the device listed when running lsusb?
• Are you running Ubuntu as a virtual machine?
• Have you tried connecting the device to a powered USB Hub or a different USB 3.0 port?

Regards,

Jesus

@Jesus_at_Intel The following are the answers to your questions:

1. NCSDK2 2.08.01.02
2. master
3. the Neural Compute Stick 2
4. The device is listed when running Isusb.
5. Ubuntu
6. I haven't tried.Thank you!

Hi @Meow10

You will need to use the OpenVINO toolkit with the Intel Neural Compute Stick 2 as the NCSDK only support the original Neural Compute Stick.

Take a look at the Get Started Guide.

Hope this helps!
