How to "Run Python Script" only?

[tombillydavid3]

Hi everyone!

I would like to use “Run Python Script” only but always got error message “The specific python path is not valid”.Settings please refer to picture 1.

For Library Path and Path, I put the same path as below:
“C:\Users\huanglikai\AppData\Local\Programs\Python\Python313\python.exe”

I have saved my python code in a file (called test.py). Settings please refer picture 2.

Wondering where I got wrong?

@tombillydavid3,

Try using this readymade test code to try if it’s working.

Path and library path are not same…and you would give location till folder not file exe

Please open details and check the error

Also in general it needs .net runtime 5 or 6 based on the python version…so check the same. Details basically will have the error details

Can you show what paths you gave and what si the python version. Python package in UiPath version and what version of .net is installed

Library path should be a .dll file and python path would generally be like python310

Cheers

Library Path:“C:\Users\huanglikai\AppData\Local\Programs\Python\Python313\python313.dll”
Path:“C:\Users\huanglikai\AppData\Local\Programs\Python\Python313”
UiPath.Python.Activities version:1.9.0
.NET version:6.0.428

[tombillydavid3]

.NET version : 6.0.36

Not sure if there’s anything relevant to what I use is Parallels Desktop?

If you have multiple versions of python installed on your machine keep only one. Remove other.

Check if the target is x64 or x86.

Your python version is the issue …current support is 3.12 or lower
