python - 使用 PIL `Image.fromarray` 创建图像会导致 AttributeError : 'list' object has no attribute '__array_interface__'

Question

我想显示 NumPy 数组中的图像，但出现此错误:

Traceback (most recent call last):
  File "E:/wittos/python/SVM/witti svm/arraytoimage.py", line 14, in <module>
   image = Image.fromarray(arry)
  File "C:\Users\MOHAMED-WITTI-ADOU\AppData\Local\Programs\Python\Python35\lib\site-packages\PIL\Image.py", line 2483, in fromarray
    arr = obj.__array_interface__
AttributeError: 'list' object has no attribute '__array_interface__'

我希望你能帮我解决这个错误。

import numpy as np
from PIL import Image

# Create a NumPy array
arry = np.array([3,3])
arry= [[25,25,25],[0,0,0],[0,0,0]]

# Create a PIL image from the NumPy array
image = Image.fromarray(arry)

# Save the image
image.save('image.jpg')

Answer 1

您创建 numpy 数组的方式是错误的。您应该将其创建为:

arry = np.array([[25,25,25],[0,0,0],[0,0,0]])

然后就可以了。因为，您正在覆盖用普通数组创建的空 numpy 数组。

import numpy as np
from PIL import Image

# Create a NumPy array
arry = np.array([[25,25,25],[0,0,0],[0,0,0]])

# Create a PIL image from the NumPy array
image = Image.fromarray(arry.astype('uint8'))

# Save the image
image.save('image.jpg')

这会起作用。
