MORP: Movidius On Raspberry Pi This repo about using Movidius neural compute sticks(NCS) on the Raspberry Pi.

It is the ongoing result of a series Meetups I have been hosting for Chicago Area Embedded Deep Learning: https://www.meetup.com/Chicago-Area-Embedded-Deep-Learning

As of 12/19/17 Movidius is saying you can have the NCS or TensorFlow, but not both:

• Build directions for a microSD card image for a Raspberry Pi with a Movidius Neural Compute Stick(NCS)
• Link to 6GB SD Card Image - RPI with NCS root password: 45tom*
• Build directions for a microSD card image with Raspberry Pi with Tensorflow

Slides from a very short demo I gave:

• Movidius NCS on RPi Demo.pdf
• Movidius NCS on RPi Demo.pptx

FAQ: What are the Movidius links?:

• https://ncsforum.movidius.com/
• https://github.com/movidius/ncappzoo
• https://github.com/movidius/ncsdk

How do I use the Pi Camera:

• https://github.com/GemHunt/movidius-on-rpi/tree/master/rpi_camera

What hardwhere do I need to get into this?

• Really you need a Ubuntu 16.04 PC, RPi, and NCS.

Does it have to be Ubuntu 16.04 PC?

• Only if you value your time! Preferably it should be a modern PC with a GPU running Ubuntu directly(not virtual). This has been a major stumpling block both in the meetup group and on the movidous forum.

What does it do?

• Infers(runs the computational graph) a Tensorflow or caffe model.

What are some NCS+RPI pros and cons?

• Pros:
• Power usage(2 Watts NCS+RPI)
• Size and wieght
• It's the first ASIC out so there is nothing to compare it to at this point
• It's true edge device (no internet needed & appliance like)
• RPI is very popular
• 15x quicker than RPI along on Deep Learning inferance.
• Cons:
• First one out: so limited support & could have much more power
• You can't access the Myraid 2 VPU with all the computer vision functionality
• Cost is high for what your getting (It's less than one thread on a CPU)
• If power and size are not an issue an old PC is more cost effective and easier to use.

How does the NCS compare to the Google AIY Vision Kit?

• https://aiyprojects.withgoogle.com/vision#list-of-materials
• Not sure yet, I ordered three of them
• The Google AIY Vision kit is a hat/bonnet that sits on top of a RPi Zero
• The Vision Kit is a hobby/learning product only, becuase you can't buy RPI Zeros in quanity and need to solder the headers on(correctly) to use it.
