'numpy' has no attribute 'bool'

The error message "'numpy' has no attribute 'bool'" is raised when you are trying to access the attribute 'bool' in the 'numpy' module, but it does not exist.

In NumPy, the boolean data type is represented by 'bool_', not 'bool'. To work with boolean values in NumPy, you can use the 'bool_' data type or the corresponding NumPy functions and methods.

Here's an example of how to use the boolean data type in NumPy:

import numpy as np

# Create a boolean array
arr = np.array([True, False, True], dtype=bool)

# Print the array
print(arr)

Make sure you have installed the latest version of NumPy and check your code to ensure you are using the correct attribute or function for boolean operations.
