When I try to run pipreqs /path/to/project it comes back with

  File "", line 1
    # !/usr/bin/env python3
    ^
SyntaxError: invalid non-printable character U+FEFF

my project contains a number of files and all of them contain their own imports. I read somewhere that it could be an issue to create a requirements.txt for a number of files so I tried to move the main file into a new dir and run pipreqs on there but again no success.

my imports look like so:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
#######################################################
# Initialise Wikipedia agent
#######################################################
import requests
import json
import aiml
import wikipedia
import numpy as np
from nltk.sem.logic import *
from nltk.inference.resolution import *
from nltk.inference import ResolutionProver
from nltk.inference.nonmonotonic import *
from nltk import *
from nltk.sem import logic
from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.metrics.pairwise import cosine_similarity
import pandas as pd
from fuzzywuzzy import fuzz
import tkinter as tk
from tkinter import filedialog
from azure.cognitiveservices.vision.computervision import ComputerVisionClient
from msrest.authentication import CognitiveServicesCredentials
import tensorflow_hub as hub

Anyone has any ideas on what it could be? Any help would be much appreciated :)

Edit:

Forgot to specify: Running Python 3.9.10 and pipreqs was installed using pip3
