AttributeError: module 'numpy' has no attribute 'int'

Question

I tried to run my code in another computer, while it successfully compiled in the original environment, this error can outta nowhere:

File "c:\vision_hw\hw_3\cv2IP.py", line 91, in SECOND_ORDER_LOG
    original = np.zeros((5,5),dtype=np.int)
File "C:\Users\brian2lee\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\numpy\__init__.py", line 284, in __getattr__
    raise AttributeError("module {!r} has no attribute " AttributeError: module 'numpy' has no attribute 'int'

I have tried reinstallin numpy but it did not work. Down below is my code:

def SECOND_ORDER_LOG (self,img):
    original = np.zeros((5,5),dtype=np.int)
    original[2,2] = 1
    kernel = np.array([[ 0,  0, -1,  0,  0],
    [ 0, -1, -2, -1,  0],
    [-1, -2, 16, -2, -1],
    [ 0, -1, -2, -1,  0],
    [ 0,  0, -1,  0,  0]])
    result = original + 1 * kernel
    sharpened = cv2.filter2D(img, -1, result)
    return sharpened

numpy.int was deprecated in NumPy 1.20 and was removed in NumPy 1.24. You can change it to numpy.int_, or just int.

Several other aliases for standard types were also removed from NumPy's namespace on the same schedule:

Deprecated name	Identical to	NumPy scalar type names
numpy.bool	bool	numpy.bool_
numpy.int	int	numpy.int_ (default), numpy.int64, or numpy.int32
numpy.float	float	numpy.float64, numpy.float_, numpy.double (equivalent)
numpy.complex	complex	numpy.complex128, numpy.complex_, numpy.cdouble (equivalent)
numpy.object	object	numpy.object_
numpy.str	str	numpy.str_
numpy.long	int	numpy.int_ (C long), numpy.longlong (largest integer type)
numpy.unicode	str	numpy.unicode_

There are similar AttributeError messages for these removals (listing them helps people find this Q&A in the search results):

• AttributeError: module 'numpy' has no attribute 'bool'.
• AttributeError: module 'numpy' has no attribute 'int'.
• AttributeError: module 'numpy' has no attribute 'float'.
• AttributeError: module 'numpy' has no attribute 'complex'.
• AttributeError: module 'numpy' has no attribute 'object'.
• AttributeError: module 'numpy' has no attribute 'str'.
• AttributeError: module 'numpy' has no attribute 'long'.
• AttributeError: module 'numpy' has no attribute 'unicode'.

np.int = np.int32
np.float = np.float64
np.bool = np.bool_

boruta = BorutaPy(estimator=rf)
boruta.fit(x, y)

Answer 3

The error you're seeing (AttributeError: module 'numpy' has no attribute 'int') suggests that you're trying to use numpy.int, which isn't an attribute in numpy. However, there's numpy.int_, which is the exact equivalent of Python's built-in int but it's available for array operations inside numpy.

If you're not working within the numpy framework for the task causing this error, it's recommended to simply use Python's built-in int.

numpy.int (along with other similar types) was deprecated in NumPy 1.20 and subsequently removed in NumPy 1.24. Therefore, using numpy.int in versions after 1.24 will raise an error. Since numpy.int is now removed, using native Python's int type is the easiest replacement when numpy's specific capabilities aren't needed.
