Invoke python method is not working. in my python script i have below mentioned library from sklearn.feature_extraction.text import TfidfVectorizer from sklearn.metrics.pairwise import cosine_similarity for this library i am getting error error message: Source: Invoke Python Method Message: Pipe is broken.

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

Hi BNK, Change the Python Version Change the UiPath.python.activities version. [image] Cheers!

I am using UiPath.python.version = 1.7.1 and Python version = 3.9 If i run same python script i am getting proper output (in Shell) but In Invoke method it is not wotking.

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] 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.

@BNK [image] Invoke Python - pipe is broken Studio I have searched the forum and have not seen an answer that solves this for me. 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 , Could you please share me your .py file and also tell me how to run that file manually on system Regards, Vinit Mhatre

sample.zip (292 Bytes) It is working in Shell but it is not working in invoke python code. I think i am facing issue with below library from sklearn.feature_extraction.text import TfidfVectorizer from sklearn.metrics.pairwise import cosine_similarity

Hi Yochi ,@Palaniyappan and @loginerror pls help on this

As you mentioned.I changed the path but it is not working.

If you don’t mind a workaround, you can use Invoke Power Shell to run your Python script. [image] [image] PythonInvokeWithPowershell.xaml (7.8 KB)
