Also, quite a good wrapper for calling python code from Labview is labpython. Install from VIPM

Thanks, Joey

Now everything in one place.

Please keep updating

Ian, I love labpython but haven't seen it working with Python 2.7.x. Do you know if there is a release that supports this?

Thanks, Joey, for a great presentation on using Python with LabVIEW and TestStand.

Does it matter which version of Python is used with the NI tools, i.e. 2.7.x or 3.x?

Yuri

Yuri, great question.

I typically use Python 2.7x and made the demos using this. You should be able to use Python 3.x for most of these but may have trouble with some of the code modules (PyDAQmx, Python LabVIEW Automation).

Hi Joey,

Sorry I haven't used LabPython in a while. I know that it works with Python 2.7.3 and Labview 2012. One known issue is that it only works in 32bit mode.

There is a discussion with known issues on the support webpage. In particular some information on redirecting output which helps debug your python code. I recommend reading.

Hope this helps

Best Regards

Ian

Thanks Joey.

It will be great if PyDAQmx and Python LabVIEW Automation can be re-tooled for Python 3 eventually. What are the chances of this hapening in the forseeable future?

For the time being, your advice is to stick with Python 2.7.x for full NI tool support?

I think it would be valuable to mention in this article about this - https://decibel.ni.com/content/docs/DOC-47034

What is the data type returned by OpenCV when I call OpenCV library using Python? Can't I get it via a 3D array? why is it like this? What data type do I need to use to get it correctly?
