  • I'm using Python APIs to control my PXI(e) SMU. I receive the following error when running my code:

Solution

This error is resolved by checking and updating the versions of NI DCPower, PyPI and Python.
The NI-DCPower Python API have been tested against NI-DCPower 2021, so older driver versions may not work. The required versions of software can be found at nidcpower.
