[Solved] Examine the code below:import numpy as np from scipy.ndimage import label arr = np.array([[1, 0], [0, 1]]) labeled, count = label(arr, connectivity=3) print(count)What is the issue with this code? | SciPy

SciPy - Image Processing (scipy.ndimage)

Examine the code below:

import numpy as np
from scipy.ndimage import label

arr = np.array([[1, 0], [0, 1]])
labeled, count = label(arr, connectivity=3)
print(count)

What is the issue with this code?

AThe connectivity parameter value 3 is invalid; it must be 1 or 2 for 2D arrays

BThe array contains zeros which cannot be labeled

CThe label function does not return two values

DThe import statement is incorrect

Step-by-Step Solution

Solution:

Step 1: Understand connectivity parameter
For 2D arrays, connectivity can only be 1 (4-connectivity) or 2 (8-connectivity).
Step 2: Identify invalid parameter
Using connectivity=3 is invalid and will raise an error.
Final Answer:
The connectivity parameter value 3 is invalid; it must be 1 or 2 for 2D arrays -> Option A
Quick Check:
Connectivity must be 1 or 2 in 2D [OK]

Quick Trick: Connectivity in 2D is 1 or 2 only [OK]
