当使用 PIL/Pillow 时，Jupyter Notebooks 现在有一个内置的 display 可以直接显示图像，没有额外的麻烦.

Updated 2021/11/17

When using PIL/Pillow, Jupyter Notebooks now have a display built-in that will show the image directly, with no extra fuss.

display(pil_im)

如果图像只是单元格中的最后一行，Jupyter 也会显示该图像(自原始帖子以来已更改).感谢 @Dean 和 @Prabhat 指出这一点.

Jupyter will also show the image if it is simply the last line in a cell (this has changed since the original post). Thanks to answers from @Dean and @Prabhat for pointing this out.

您也可以使用 IPython 的 display 模块来加载图像.您可以从 文档.

You can also use IPython's display module to load the image. You can read more from the doc.

from IPython.display import Image 
pil_img = Image(filename='data/empire.jpg')
display(pil_img)

来自 PIL.Image 对象

由于OP的要求是使用PIL，如果你想显示内联图像，你可以使用matplotlib.pyplot.imshow和numpy.asarray也像这样:

From PIL.Image Object

As OP's requirement is to use PIL, if you want to show inline image, you can use matplotlib.pyplot.imshow with numpy.asarray like this too:

from matplotlib.pyplot import imshow
import numpy as np
from PIL import Image

%matplotlib inline
pil_im = Image.open('data/empire.jpg', 'r')
imshow(np.asarray(pil_im))

如果您只需要预览而不是内联，您可以像这样使用 show:

If you only require a preview rather than an inline, you may just use show like this:

pil_im = Image.open('data/empire.jpg', 'r')
pil_im.show()
