S100 OpenExplorer

# #OpenExplorer Introduction

## #What is OE

OE is the abbreviation of OpenExplorer, which is an full lifecycle development platform based on Horizon's self-developed computing platform.

OE provides Horizon partners with rich and diverse algorithm resources, flexible and efficient development tools, and easy-to-use development frameworks. The features and advantages of OE are as follows:

To help you deploy various solutions to a series of Horizon dev boards, we provide a full-volume development package, called OE package, which integrates the development environment deployment, application reference solution sample code, user manuals, etc. After you get the OE package, you can first follow the steps below to understand the OE:

1. First refer to Release Content for the directory structure of the release package.

2. Then refer to Environment Deployment for the development environment and runtime environment deployment.

3. Next, refer to Post-training Quantization (PTQ), Quantized Awareness Training (QAT) and Embedded Application Development to complete the entire process of model conversion and deployment.

For more tutorials on using the OE package, please refer to the instruction manual below. We believe Horizon's OE package can make your development more efficient and easier!

## #Release Content

### #package

The `package` directory contains some base libraries and components for the distribution to run.

- package.board

  The `package.board` contains the board-side executables.

  - The `hrt_model_exec` is a model execution tool that can be used directly on the dev board to evaluate the inference performance of the model and obtain model information, which provides funcitons including model inference `infer`, model performance analysis `perf` and viewing model information `model_info`.
  - The install_linux.sh and install_qnx.sh are installation scripts that can install the `hrt` tool on the specified development board in one go. You can choose the appropriate script according to the operating system of your development board.

- package.host

  The `package.host` folder contains the environment dependencies and tool dependencies for the distribution in the x86 development environment. By executing the script `install.sh` in this directory, you can install all environment and tool dependencies on the development machine. By executing the script `resolve.sh` in this directory, you can download the cross-compilation tools and torch etc. dependencies.

### #samples

The `samples` contains ai_toolchain, model_zoo and ucp_tutorial.

- ai_toolchain provides a series of samples of some model algorithms (horizon_model_train_samples: samples of floating-point model training frameworks; horizon_model_convert_sample: a conversion sample for floating-point to fixed-point models; model_zoo: a model library that is used to place the original model and runtime model for the toolchain sample model compilation).
- model_zoo, soft link points to the model_zoo path in the ai_toolchain folder.
- ucp_tutorial, the UCP samples package, which provides the necessary dependencies for UCP and related samples.

### #run_docker.sh

In case the evaluation dataset and the required docker download for the OE package are completed, you can use the command `sh run_docker.sh {dataset path}` to automatically mount the OE package and start the docker.
