4.2.6. Setting Required Environment Variables

Set the OpenVINO™ toolkit and FPGA AI Suite environment variables for your operating system as follows:
  • Linux* systems:

    Set the OpenVINO™ toolkit and FPGA AI Suite environment variables by running the following commands from a bash-style shell (do not use /bin/dash or /bin/tcsh) or by adding the commands to your .bashrc file. If you did not install OpenVINO™ toolkit into the default location, adjust the third command to use your OpenVINO™ toolkit location:

    source ~/build-openvino-dev/openvino_env/bin/activate
    
    unset python_version
    
    source /opt/intel/openvino_2024/setupvars.sh
    
    source /opt/altera/fpga_ai_suite_2025.3/dla/setupvars.sh
  • Windows* systems:

    Set the OpenVINO™ toolkit and FPGA AI Suite environment variables from a command prompt with the following commands. If you did not install OpenVINO™ toolkit into the default location, adjust the first command appropriately:

    "C:\Program Files (x86)\Intel\openvino_2024\setupvars.bat"
    
    "C:\altera_pro\2025.3\fpga_ai_suite\dla\setupvars.bat"
Tip: If you have multiple versions of FPGA AI Suite installed on your system, you can use source commands to switch between them. To switch, source the environment variable setup scripts for the version of FPGA AI Suite that you want to run. You must ensure that you also have the required OpenVINO™ toolkit version available.
For example, if you want to run FPGA AI Suite 2023.3, run the following commands:
source ~/build-openvino-dev/openvino_env/bin/activate

unset python_version

source /opt/intel/openvino_2022/setupvars.sh

source /opt/intel/fpga_ai_suite_2023.3/dla/setupvars.sh

In some older versions of FPGA AI Suite, the environment variable setting script is called init_env.sh and might be in a slightly different path (dla/bin/init_env.sh).
