Issue with using python functions

[sherzaad]

Hi,

I am trying to run a simple python script in Labview but I am getting an error code 1663 that I cannot seem to find any information on.

Anyone have any ideas what it is and why I'm getting this error.

I have attached the VI and script I am trying to execute.

Thanks in advance

There's at least some information on error 1663:

yeah ... thanks....

They do not appear to have a clear solution either....

Any other ideas how to resolve the issue I'm facing?

I still am having trouble understanding why I get this error code... perhaps if there is a good explanation if what triggers it, it might help me understand what might be causing it at my end! 🙂

Not really.

Pretty sure it's something to do with the Python version.

Which did you install? And how (Anaconda, spyder, PyCharm, etc.)? Does Python itself work? Do you have other Python versions installed? And so on...

Googling the hex error code gives more results:

I'm using Python 3.6.6 Windows x86 embeddable zip file  (I have LABVIEW 2018 32-bit version installed on my machine) which I downloaded from https://www.python.org/downloads/release/python-366/

I've put the python folder in my C drive. and yes the python itself works...

did you :

(Windows) If you install Python 3.6, add the directory containing python36.dll to the system path

As indicated here.

That's all I have...

Guess that's your chance to be a hero; if you post the solution if you ever find it.

there is somewhat a possibility that Labview cannot run nipythonHost.exe in ....(your installation folder)\National Instruments\Shared\NIPythonInterface\ folder. A quick solution to the problem is to find nipythonHost.exe in the above direction and copy-paste it into ...\National Instruments\Labview 2020\ folder. I've had the same issue as you (checked bitness, checked system path) and I end up find out that this is a solution.
