Compatibility of Python Virtual Environments with LabVIEW

Issue Details

What versions of LabVIEW are compatible with Python virtual environments? 

Solution

LabVIEW 2023 Q1 supports calling Python installed in virtual environments. Older version cannot call Python installed within virtual environments.

The supported Python environments, installed from The Python Software Foundation are:

• LabVIEW 2018 to 2020:
  • Native Python 2.7 and 3.6.
• LabVIEW 2021 and 2022:
  • Native Python 3.6, 3.7, 3.8, and 3.9.
  • Note: Support for Python 2.7 is deprecated.
• LabVIEW 2023Q1, 2023Q3, 2024Q1:
  • Native Python 3.6 through 3.10
  • Python Virtual Environments using Open Anaconda 2 and 3 (32 and 64 bit) and Virtual Env. (venv).
• LabVIEW 2025Q1 and 2025Q3:
  • Native Python 3.9 through 3.12 
  • Python Virtual Environments using Open Anaconda 2 and 3 (32 and 64 bit) and Virtual Env. (venv).

Additional Information

• Unsupported Python versions may work with the LabVIEW Python functions, NI recommends using supported versions of Python only.
• Ensure that the bitness of Python corresponds to the bitness of LabVIEW installed on the machine.
• Use the Python Node to integrate Python Code in LabVIEW using code created in supported Python versions.
• As of June 2, 2020, the Python Integration Toolkit by Enthought is at end of life. For information on supported environments with the Python Integration Toolkit by Enthought, see the specifications on their website or contact Enthought support.
