[英]how to display multiple pngs in a grid using jupyter notebook
我有一個文件名列表,位於與jupyter筆記本相同的文件夾中。
fnames = ['foo.png', 'my_img.png', 'img1.png', ..... 'last_img.png']
我想在筆記本輸出單元格的網格中顯示這些圖像,指定:
試試這個
import os
import numpy as np
import matplotlib.pyplot as plt
directory = "./Images/"
images = os.listdir(directory)
fig = plt.figure(figsize=(10, 10))
columns = 2
rows = np.ceil(len(images))
for x, i in enumerate(images):
path = os.path.join("./Images/",i)
img = plt.imread(path)
fig.add_subplot(rows, columns, x+1)
plt.imshow(img)
plt.show()
更深入的潛水,您可以使用ipywidgets
作為替代方案在Tabs
查看 :
import os
import ipywidgets as widgets
from IPython.display import display
# Define a useful function
def get_image(f_path):
'''
Returns the image from a path
'''
img_labs = ['jpg','png']
if any(x in img_labs for x in f_path.split('.')):
file = os.path.join(folder,f_path)
image = open(file,'rb').read()
return image
# Do the actual work here
folder = 'Some Path to a Folder of Images'
files = os.listdir(folder)
images = [get_image(x) for x in files]
children = [widgets.Image(value = img) for img in images if str(type(img)) != '<class \'NoneType\'>']
labels = ['{}'.format(i) for i in range(len(children))]
# Customize your layout here:
box_layout = widgets.Layout(
display='flex',
flex_flow='column',
align_items='stretch',
border='solid',
width='50%')
# Create the widget
tab = widgets.Tab()
tab.children = children
# Label em'!
for i in range(len(children)):
tab.set_title(i,labels[i])
display(tab)
