python AttributeError: 'QPixmap' object has no attribute 'shape'
时间: 2023-10-15 09:07:37 浏览: 330
`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:
1. 使用QPixmap的width()和height()函数来获取图像的宽度和高度。
2. 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:
```python
import random
my_list = [1, 2, 3, 4, 5]
random_choice = random.choice(my_list)
print(random_choice)
```
