The xlnx-vai-lib-samples snap provides a set of pre-built Vitis AI sample applications that are available in source form in the Vitis-AI Github repository. Source code for the sample apps can be found at:
https://github.com/Xilinx/Vitis-AI/tree/v1.3.2/demo/Vitis-AI-Library/samples/
| Info |
|---|
The current version supports Vitis-AI v1.3.2. The compatible models are v1.3.1. |
...
The xlnx-vai-lib-samples app provides wrappers for these tests, implemented as “sub-applications”, which will check the supplied “sample app” and “model name” arguments, and confirm that they are a valid combination. Then, the snap will call the appropriate sub-application with the proper arguments such that the proper test-specific application is called. The snap will also download models on demand from the Xilinx model zoo and store them locally for future use. info
