# Neural Compute Application Zoo (ncappzoo)
[](https://github.com/opencv/dldt/releases/tag/2020.1)
[](LICENSE)
Welcome to the Neural Compute Application Zoo (_ncappzoo_). This repository is a place for any interested developers to share their projects (code and Neural Network content) that make use of the [Intel® Neural Compute Stick 2 (Intel® NCS2)](https://software.intel.com/en-us/neural-compute-stick) or the original [Intel® Movidius™ Neural Compute Stick](https://software.intel.com/en-us/movidius-ncs) and the Deep Learning Deployment Toolkit (DLDT) portion of the [OpenVINO™ Toolkit](https://software.intel.com/en-us/openvino-toolkit).
The _ncappzoo_ is a community repository with many content owners and maintainers. All _ncappzoo_ content is open source and being made available in this central location for others to download, experiment with, modify, build upon, and learn from.
## _ncappzoo_ Quick Start
If you have an Intel® NCS2 (or the first generation Intel® Movidus™ NCS) device and want to jump into the _ncappzoo_, follow these steps:
Clone the repo with the following command:
```bash
git clone https://github.com/movidius/ncappzoo.git
```
Run this command inside of any app/network folder to check your system software dependencies for that particular sample:
```bash
make install_reqs
```
If the script returns successfully, you're ready to run the app or network sample!
## _ncappzoo_ Apps and Networks
Explore apps by opening a terminal window navigating to any directory under **_ncappzoo_/apps** and execute this command:
```bash
make run
```
Explore the neural networks by navigating to any network directory under **_ncappzoo_/networks** and execute the same command:
```bash
make run
```
Thats it! All of the network and app directories have simple consistent makefiles. To see other make targets supported from these directories just execute this command:
```bash
make help
```
## _ncappzoo_ Repository Branches
There are main three branches in the repository; their descriptions are below. **The master branch is the one most developers will want.** The others are provided for legacy compatibility.
- **master** branch: This is the most current branch, and the content relies on the DLDT from the OpenVINO™ Toolkit. This is the only branch that is compatible with the Intel® NCS2 however, it is also compatible with the original Intel® Movidius™ NCS device.
- **ncsdk2** branch: This branch is a legacy branch and the content relies on the NCSDK 2.x tools and APIs rather than the OpenVINO™ toolkit. This branch is only compatible with the original Intel® Movidius™ NCS device and is **NOT** compatible with the Intel® NCS2 device.
- **ncsdk1** branch: This branch is a legacy branch and the content relies on the NCSDK 1.x tools and APIs rather than OpenVINO™ toolkit. This branch is only compatible with the original Intel® Movidius™ Neural Compute Stick and is **NOT** compatible with the Intel® NCS2 device.
You can use the following git command to use the master branch of the repo:
```bash
git clone https://github.com/movidius/ncappzoo.git
```
## _ncappzoo_ Compatibility Requirements
### Hardware compatibility
The projects in the _ncappzoo_ are periodically tested on Intel® x86-64 Systems unless otherwise stated in the project's README.md file. Although not tested on other harware platforms most projects should also work on any hardware which can run the OpenVINO™ toolkit including the Raspberry Pi 3/3B/3B+/4B hardware
The projects in the _ncappzoo_ work on both the Intel® NCS2 and the original Intel® Movidius NCS devices.
### Operating System Compatibility
The projects in the _ncappzoo_ are tested and known to work on the **Ubuntu 18.04** OS. These projects will likely work on other Linux based operating systems as well but they aren't tested on those unless explicitly stated in the project's README.md file and there may be some tweaks required as well. If any specific issues are found for other OSes please submit a pull request as broad compatibility is desirable.
### OpenVINO and DLDT Compatibility
The projects in the **master branch** depend on the Deep Learning Deployment Toolkit (DLDT) portion of the OpenVINO™ toolkit. There are two flavors of the the OpenVINO™ toolkit's DLDT:
- The [Intel® Distribution of the OpenVINO™ toolkit](https://software.intel.com/en-us/openvino-toolkit) is a binary installation available for supported platforms. Here are some links regarding the Intel Distribution of the OpenVINO™ Toolkit and the Intel® NCS2
- Getting started web page: https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick
- Getting Started Video for Linux: https://youtu.be/AeEjQKKkPzg?list=PL61cFkSnEEmOF3AJvLtlDTSbwjlCP4iCs
- OpenVINO Toolkit documentation: https://docs.openvinotoolkit.org/latest/index.html
- The [open source distribution of the OpenVINO™ toolkit DLDT](https://github.com/opencv/dldt). This is the means by which the Intel® NCS2 device can be used with most single board computers on the market and is also helpful for other non-Ubuntu development systems. Here are some links regarding the open source distribution of the OpenVINO™ with the Intel® NCS2:
- Applies to all target system: https://software.intel.com/en-us/articles/intel-neural-compute-stick-2-and-open-source-openvino-toolkit
- ARMv7: https://software.intel.com/en-us/articles/ARM-sbc-and-NCS2
- ARM64: https://software.intel.com/en-us/articles/ARM64-sbc-and-NCS2
- Python on all: https://software.intel.com/en-us/articles/python3-sbc-and-ncs2
**Note:** When using the open source distribution of the OpenVINO™ toolkit, you may need to modify your shell's path and environment variables to point to the toolkit's directories.
The projects in the _ncappzoo_ work with both flavors of the OpenVINO™ Toolkit and unless otherwise specified in a project's README.md file all projects are targeted for the **OpenVINO™ Toolkit 2020.1 release**.
### OpenCV Compatibility
Some projects also rely on OpenCV. For these projects, OpenCV distributed with the OpenVINO™ release is the recommended version. Other versions may also work but are not tested an may require tweaks to get working.
### Python Compatibility
The Python projects in the _ncappzoo_ rely on Python 3.5, unless otherwise stated in the individual project's README.
### Raspberry Pi Compatibility
The _ncappzoo_ is compatible with the Raspberry Pi 3 B+ and the Raspberry Pi 4. Some additional configuration steps are required:
#### Intel® Distribution of OpenVINO™ for Raspbian* OS
The **Intel® Distribution of OpenVINO™ toolkit for Raspbian OS** does not include the Model Optimizer. To use the _ncappzoo_, you must clone the open source version of the OpenVINO™ Deep Learning Development Toolkit (DLDT) and use that version of the Model Optimizer. Clone the repository, install dependencies for TensorFlow* and Caffe*, and set up your **PATH** and **PYTHONPATH** variables to point to the Model Optimizer:
```
cd ~
git clone https://github.com/opencv/dldt.git
cd dldt/model-optimizer
pip3 install -r requirements_tf.txt
pip3 install -r requirements_caffe.txt
export PATH=~/dldt/model-optimizer:$PATH
export PYTHONPATH=~/dldt/model-optmizer:$PYTHONPATH
```
#### Open Source OpenVINO™ Deep Learning Development Toolkit (DLDT)
To setup the open source version of OpenVINO™ with your Raspberry Pi, add to the PATH, PYTHONPATH, and LD_LIBRARY_PATH environment variables the location of the build Inference Engine libraries and Python API.
