Pipreqs not including all packages?

I currently have a conda environment tf_gpu and I pip installed pipreqs in it to auto generate requirements.txt

Now, in my project folder, I have app.py with the imports :

import os
from dotenv import load_dotenv
from flask import Flask, request
from predict import get_recs
import urllib.request

Also, predict uses pandas, scipy, numpy, pickle

So, but the requirements.txt generated by pipreqs using pipreqs ./ inside the project folder only gets me the following:

Flask==2.1.3
numpy==1.23.3
pandas==1.4.4
scipy==1.9.1

Why is python-dotenv not included? It isnt a standard library right? So what’s happening here?

Answer

According to the open issues in the GitHub repo, some packages don’t map well. You could try opening an issue for this package.
