[Solved] Identify the issue in this code snippet:import numpy as np arr = np.array([1.0, 2.0], dtype=np.float64) arr = arr.astype('float16') print(arr.dtype) | NumPy

NumPy - Array Data Types

Identify the issue in this code snippet:

import numpy as np
arr = np.array([1.0, 2.0], dtype=np.float64)
arr = arr.astype('float16')
print(arr.dtype)

ANo issue; code runs correctly and prints float16

Bastype conversion from float64 to float16 may cause precision loss

Cfloat16 is not a valid dtype in NumPy

DCannot convert float64 array to float16 using astype

Step-by-Step Solution

Solution:

Step 1: Analyze dtype conversion
The code converts a float64 array to float16 using astype.
Step 2: Understand float16 limitations
float16 has lower precision and smaller range, so conversion may lose precision.
Final Answer:
astype conversion from float64 to float16 may cause precision loss -> Option B
Quick Check:
astype allows conversion but beware of precision loss [OK]

Quick Trick: astype converts types but watch for precision loss [OK]
