python AttributeError: 'QPixmap' object has no attribute 'shape'

QPixmap is an object from the PyQt library that represents an image. The error message you received indicates that you are trying to access the shape attribute of a QPixmap object, but this attribute does not exist.
In Python, the shape attribute is commonly used with NumPy arrays to return the dimensions of the array. However, QPixmap objects do not have this attribute.
To fix this error, you need to check how you are using the shape attribute with your QPixmap object and remove it. If you need to get the dimensions of the image represented by the QPixmap object, you can use the width() and height() methods instead.

python AttributeError: 'QPixmap' object has no attribute 'shape'如何修正

这个错误提示表明，你正在尝试调用一个名为“shape”的属性，但是该属性不存在于QPixmap对象中。
QPixmap是一个Qt库中的图像处理类，它没有shape属性，因此你需要用其他方法来获取图像的形状信息。可能的解决方法包括：

使用QPixmap的width()和height()函数来获取图像的宽度和高度。

将QPixmap对象转换为numpy数组，然后使用numpy数组的shape属性来获取形状信息。可以使用QPixmap.toImage()函数将QPixmap对象转换为QImage对象，然后使用QImage的toNumpy()函数将其转换为numpy数组。

例如，下面是一种可能的解决方法：
import numpy as np
from PyQt5.QtGui import QPixmap, QImage

pixmap = QPixmap("image.png")
image = pixmap.toImage()
array = np.array(image.toNumpy())
shape = array.shape
print(shape)

python2 AttributeError: module object has no attribute choice

这个错误通常是因为在 Python2 中，choice 函数不在全局命名空间中，需要从 random 模块中导入。你可以尝试将代码中的 choice 函数改为 random.choice 来解决该问题。例如：
import random

my_list = [1, 2, 3, 4, 5]
random_choice = random.choice(my_list)
print(random_choice)
