[Python] No configs specified for inline runner: MRJob error

so, I'm pretty new to MRJob, so don't be rude please.

I tried write a program (using ChatGPT), that checks tf*idf for specified line in 3 text files; however, i always get the same error: "No configs specified for inline runner", can somebody please explain what's the problem, since googleing didn't help.

code:

from mrjob.job import MRJob
import math
import os
import re

WORD_RE = re.compile(r"\b\w+\b")

class TFIDFJob(MRJob):

def configure_args(self):
super(TFIDFJob, self).configure_args()
self.add_passthru_arg('--query', type=str, help='Search query')

def mapper(self, _, line):
file_name, content = line.split("\t", 1)
words = WORD_RE.findall(content.lower())
total_words = len(words)

for word in words:
yield (word, file_name), 1

yield ("__TOTAL__", file_name), total_words

def reducer(self, key, values):
if key[0] == "__TOTAL__":
yield key[1], sum(values)
else:
word, file_name = key
word_count = sum(values)
yield (file_name, word), word_count

if __name__ == "__main__":
search_query = input("Enter query: ")

files = []
for file_name in ["file1.txt", "file2.txt", "file3.txt"]:
with open(file_name, 'r', encoding='utf-8') as f:
files.append((file_name, f.read()))

job = TFIDFJob(args=['--query', search_query])
with job.make_runner() as runner:
runner.run()
for key, value in job.parse_output(runner.cat_output()):
print(f"{key}: {value}")


and the error i get:

$ python3 hw1.py file1.txt file2.txt file3.txt
Enter query: 123
