我使用的Tensorflow为诗人教程的图像进行分类。我使用下面的代码到的图像进行分类,但想在numpy的阵列作为图像而不是JPEG,如何将代码必须改变养活?判断一个numpy的阵列图像
import tensorflow as tf
import sys
# change this as you see fit
image_path = sys.argv[1]
# Read in the image_data
image_data = tf.gfile.FastGFile(image_path, 'rb').read()
# Loads label file, strips off carriage return
label_lines = [line.rstrip() for line
in tf.gfile.GFile("/tf_files/retrained_labels.txt")]
# Unpersists graph from file
with tf.gfile.FastGFile("/tf_files/retrained_graph.pb", 'rb') as f:
graph_def = tf.GraphDef()
graph_def.ParseFromString(f.read())
_ = tf.import_graph_def(graph_def, name='')
with tf.Session() as sess:
# 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))
image_data = tf.gfile.FastGFile(image_path, 'rb').read()
- 如果我不是从文件中读取,我想我不需要这些。
predictions = sess.run(softmax_tensor, {'DecodeJpeg/contents:0': image_data})
- 我知道我不需要重写feed_dict的这个方面,但是我应该怎么做呢?
总的来说,我怎么能确保一个nparray我有一个代表图像进行适当用于预测?
