Setting environment for ST Edge AI Core ¶

Overview ¶

The ST Edge AI Core package is mainly a complete self-contained application package. For a given target, it is recommanded to install the associated core tool-chain and adding the directory to the PATH environment variable.

Note

In this article, %STEDGEAI_CORE_DIR% designates the root path where the ST Edge AI Core components are installed.

Example for STM32 target ¶

For the generation of a relocatable binary network (refer to “STM32 Relocatable binary model support” article) or to evaluate the runtime memory size, a GNU ARM Embedded tool-chain ( 'arm-none-eabi-' prefix) should be available in the PATH.

Environment settings ¶

Windows 10 64-bit or newer ¶

Open a Windows command prompt

Update system PATH variable

set PATH=%STEDGEAI_CORE_DIR%\Utilities\windows;%PATH%

[ Alternative solution ] Create an alias with doskey command

doskey stedgeai="%STEDGEAI_CORE_DIR%\Utilities\windows\stedgeai.exe" $*

Verify the environment (displayed versions depend on installed components)

$  stedgeai --version
ST Edge AI Core v2.0.0-A1
    ISPU 1.1.0
    MLC 1.1.0
    StellarStudioAI 2.0.0
    STM32CubeAI 10.0.0
    STM32MP2 1.0

or to have also the version of the embedded Python modules (displayed modules depend on installed components)

$ stedgeai --tools-version
stedgeai - ST Edge AI Core v1.0.0
    - Python version   : 3.9.13
    - Numpy version    : 1.23.5
    - TF version       : 2.15.1
    - TF Keras version : 2.15.0
    - ONNX version     : 1.15.0
    - ONNX RT version  : 1.18.1

Ubuntu 20.4 and Ubuntu 22.4 (or derived) ¶

Similar setting of the environment is expected. A native GCC (X86_64) tool-chain should be accessible in the system path.

            export PATH=$STEDGEAI_CORE_DIR/Utilities/linux:$PATH

           

macOS (x64) - Minimum version High Sierra ¶

Similar setting of the environment is expected. A native GCC (X86_64) tool-chain should be accessible in the system path.

            export PATH=$STEDGEAI_CORE_DIR/Utilities/mac:$PATH
