Hi [BNK](https://forum.uipath.com/u/BNK), 1. Change the Python Version 2. Change the UiPath.python.[activities](https://docs.uipath.com/activities/docs/introduction) version. ![image](https://global.discourse-cdn.com/uipath/original/4X/6/b/7/6b7605fc0a1228301688139ba717b16f54ae3e1e.png) Cheers! ---

I added the system variable for both python and pip also. still i am getting error My python script: import pandas as pd import spacy from sklearn.feature\_extraction.text import TfidfVectorizer from sklearn.metrics.pairwise import cosine\_similarity import sys def run\_123(text): return " Hi " + text if **name** == “ **main** ”: run(sys.argv[1]) Error: ![image](https://global.discourse-cdn.com/uipath/original/4X/1/c/1/1c1daf7d4457acdcbe19bcdcfc0f8c3089625255.png) I am able to run simple programs in Invoke Python method. In above program i am getting error in import statements. I tested this same code locally it is working fine but it is not working in invoke python code. ---

I have been using invoked python methods (and some existing robots are still working with this method) for a number of years. However, after the last upgrade 2021.10.4 I am getting the error below, generated from the invoke python method activity. I have tried this on a number of different python code bases to see if it changed the outcome and the summary is: If the python code base invoked is a single function o… check the reference ---

Hi @BNK Here is my suggestion, if the Python invoke method does not work. Open the cmd prompt and change the directory path to the python folder “cd /d C:\Program Files\Python310” and enter python.py script path and also you can add arguments at the end of the line, test it, and if works Use UiPath activities for cmd prompt automation in that you can able to send the change directory path, python.py path, and any argument values. Try this and let me know ---

If you don’t mind a workaround, you can use `Invoke Power Shell` to run your Python script. ![image](https://global.discourse-cdn.com/uipath/original/4X/c/3/9/c394cc06a96d16d245ff8eb8528bd88f8fbe7c5c.png) ![image](https://global.discourse-cdn.com/uipath/original/4X/3/d/b/3db5d460c4cd5fa75973ca3f5d0610077799bf5b.png) [PythonInvokeWithPowershell.xaml](https://forum.uipath.com/uploads/short-url/oTHd4eYJqgeVwPnfDt2wfxqukB9.xaml) (7.8 KB) ---
