SciPy - Sparse Matrices (scipy.sparse)
Which of the following is the correct way to create a CSR matrix from a dense NumPy array
arr using SciPy?Which of the following is the correct way to create a CSR matrix from a dense NumPy array arr using SciPy?
easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall SciPy CSR matrix creation syntax
The correct function to create a CSR matrix from a dense array iscsr_matrix()fromscipy.sparse.Step 2: Check each option
csr_matrix(arr) uses the correct function name and syntax. Options B, C, and D are incorrect or invalid function calls.Final Answer:
csr_matrix(arr) -> Option DQuick Check:
Use csr_matrix() to convert dense to CSR [OK]
Quick Trick: Use csr_matrix() function from scipy.sparse [OK]
Common Mistakes:
MISTAKES- Using incorrect function names like csr() or sparse.csr()
- Trying to call to_csr() method which doesn't exist
- Confusing with other sparse formats like COO
