Discrepancies in modules spotted but no modules listed

**Output**

```
Some modules were not successfully imported, and it means either of the two things :
1. No such module(s) (just ignore this warning then)
2. Module(s) not found in your system. (pip install )
There seems to be discrepancies in following module(s) :
Quitting.
```

imports -
"import numpy as np
from PIL import Image
import cv2
import matplotlib.pyplot as plt
import pickle

from matplotlib import style
import time
"

The issue shows a warning message about module discrepancies but no modules listed, after importing numpy, PIL, cv2, matplotlib, pickle, and time. Look at the code that detects and reports these discrepancies, likely in the module that parses imports or checks system modules. Run the tool on a sample script with those imports to reproduce the warning. Check how the list of discrepancies is built and why it might be empty.
