我正在尝试对图像识别进行编码,以针对不同的动物图像训练系统,这就是代码。我正在使用anaconda作为解释器, 为环境使用pycharm。
import tensorflow as tf
import os, sys
from PIL import Image
image_path = 'test_images/leopard2.jpg'
size = (299, 299)
infile = image_path
outfile = os.path.splitext(infile)[0] + '_resized.jpg'
try:
im = Image.open(infile)
im.thumbnail(size, Image.ANTIALIAS)
old_im_size = im.size
## By default, black colour would be used as the background for padding!
new_im = Image.new("RGB", size)
new_im.paste(im,(int(size[0]-old_im_size[0])/2,int(size[1]-
old_im_size[1])/2))
new_im.save(outfile, "JPEG")
except IOError:
print("Cannot resize '%s'") %infile
# Read in the image_data
image_data = tf.gfile.FastGFile(outfile, 'rb').read()
# Loads label file, strips off carriage return
label_lines = [line.rstrip() for line
in tf.gfile.GFile("output_labels.txt")]
# Unpersists graph from file
with tf.gfile.FastGFile("output_graph.pb", 'rb') as f:
graph_def = tf.GraphDef()
graph_def.ParseFromString(f.read())
_ = tf.import_graph_def(graph_def, name='')
init_ops = tf.global_variables_initializer()
with tf.Session() as sess:
sess.run(init_ops)
# Feed the image_data as input to the graph and get first prediction
softmax_tensor = sess.graph.get_tensor_by_name('final_result:0')
predictions = sess.run(softmax_tensor, \
{'DecodeJpeg/contents:0': image_data})
# Sort to show labels of first prediction in order of confidence
top_k = predictions[0].argsort()[-len(predictions[0]):][::-1]
for node_id in top_k:
human_string = label_lines[node_id]
score = predictions[0][node_id]
print('%s (score = %.5f)' % (human_string, score))
os.remove(outfile)
出现的错误是

我正在使用的图像为jpeg格式,并且位于代码中定义的正确路径中。有人知道这是什么问题吗?
答案 0 :(得分:1)
您的2除法不会被int()全部包裹。如果您的(size[0]-old_im_size[0])
或(size[1]- old_im_size[1])
出现奇数,则代码将中断。
尝试一下:
new_im.paste(im,(int((size[0]-old_im_size[0])/2), int((size[1]- old_im_size[1])/2)))

您可以使用int()环绕所获取的float对象,也可以使用//
而不是/
进行除法。看到这个:-
>>> t = 44/2
>>> t
22.0
>>> int(t)
22
>>> t = 44//2
>>> t
22
