eIQ - A Python Framework for eIQ on i.MX Processors
PyeIQ is written on top of eIQ™ ML Software Development Environment and provides a set of Python classes
allowing the user to run Machine Learning applications in a simplified and efficiently way without spending time on
cross-compilations, deployments or reading extensive guides.
Installation
- Method 1: Use pip3 tool to install the package located at PyPI repository:
$ pip3 install pyeiq
- Method 2: Get the latest tarball Download files and copy it to the board:
$ pip3 install <tarball>
pyeiq tarball:
How to Run Samples
- Start the manager tool:
$ pyeiq
- The above command returns the PyeIQ manager tool options:
| Manager Tool Command | Description | Example |
| pyeiq --list-apps | List the available applications. | |
| pyeiq --list-demos | List the available demos. | |
| pyeiq --run <app_name/demo_name> | Run the application or demo. | # pyeiq --run object_detection_tflite |
| pyeiq --info <app_name/demo_name> | Application or demo short description and usage. | |
| pyeiq --clear-cache | Clear cached media generated by demos. | # pyeiq --info object_detection_tflite |
PyeIQ Demos
- covid19_detection
- object_classification_tflite
- object_detection_tflite
Demos Example - Running Object Detection
Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. Well-researched domains of object detection include face detection and pedestrian detection. Object detection has applications in many areas of computer vision, including image retrieval and video surveillance.
- Run the Object Detection Default Image demo using the following line:
$ pyeiq --run object_detection_tflite
* This runs inference on a default image:
- Run the Object Detection Custom Image demo using the following line:
$ pyeiq --run object_detection_tflite --image=/path_to_the_image
- Run the Object Detection Video File using the following line:
$ pyeiq --run object_detection_tflite --video_src=/path_to_the_video
- Run the Object Detection Video Camera or Webcam using the following line:
$ pyeiq --run object_detection_tflite --video_src=/dev/video<index>
