Python Script import error

[alfroc]

Hi,

I’m trying to integrate in KNIME a working Python program in a Python Script (legacy) Node, but some import statements seem don’t work:

import requests
from bs4 import BeautifulSoup
import pandas as pd
import os

No module named ‘requests’
Traceback (most recent call last):
File “”, line 1, in
ModuleNotFoundError: No module named ‘requests’

No module named ‘bs4’
Traceback (most recent call last):
File “”, line 1, in
ModuleNotFoundError: No module named ‘bs4’

Not being a Python expert, I’m asking if you have any suggestions.

Many thanks,
Alfredo

See here:

Have you configured Python correctly? Preferences => KNIME => Python (Legacy)

Can you maybe switch to the “normal” Python Scropt node (non-legacy)?

Hi @MartinDDDD,
Thanks, the documentation was very helpful.
Solved it using the Anaconda Powershell prompt:

conda install --name py36_knime request
conda install --name py36_knime bs4
conda install --name py36_knime py4j

Regards,
Alfredo
