NameError in Tensorflow und Python

Question

Diese Zeile zeigt an, dass der Code den Verarbeitungsteil "Bilder verarbeiten/Young-Bengal-tiger.jpg ..." gestartet hat.

Ich versuche, die Fehler unten zu lösen:

In [50]: def extract_features(list_images): 
    ...: nb_features = 2048 
    ...: features = np.empty((len(list_images),nb_features)) 
    ...: labels = [] 
    ...: 
    ...: create_graph() 
    ...: 
    ...: with tf.Session() as sess: 
    ...: 
    ...:  next_to_last_tensor = sess.graph.get_tensor_by_name('pool_3:0') 
    ...: 
    ...: for ind, image in enumerate(list_images): 
    ...:  if (ind%100 == 0): 
    ...:   print('Processing %s...' % (image)) 
    ...: if not gfile.Exists(image): 
    ...:  tf.logging.fatal('File does not exist %s', image) 
    ...: 
    ...:  image_data = gfile.FastGFile(image, 'rb').read() 
    ...:  predictions = sess.run(next_to_last_tensor,{'DecodeJpeg/contents:0': image_data}) 
    ...: features[ind,:] = np.squeeze(predictions) 
    ...: labels.append(re.split('_\d+',image.split('/')[1])[0]) 
    ...: 
    ...: return features, labels 
Processing images/Young-Bengal-tiger.jpg...
