Calling Python from Labview

[LED47]

A very general question

Currently using a Python program to calculate spectrum parameters

Starts and terminates a Python interpreter each time

In order to speed up my processing is there any way that I can start the Python interpreter, calculate without terminating?

I'm thinking this would save time and I could calculate multiple spectrums in succession.

You can use the built in Python node. You can open the node and leave it open when the VI runs and close it when your program exits. I found the first calculation in the node is "slow", then subsequent calls are significantly faster.

Yes that makes sense Thank you
