问题描述

我最近安装了适用于 Windows 的 Tensorflow.我正在尝试一个基本教程，我需要在其中访问包含图像子文件夹的文件夹.

I recently installed Tensorflow for Windows. I am attempting a basic tutorial in which I need to access a folder containing sub-folders of images.

我无法访问图像文件夹，因为访问被拒绝".这发生在 Anaconda 4.2 提示符和 Pycharm 中，并使用基本的 Python 3.5 发行版.

I am not able to access the folder of images because "access is denied". This happens both in the Anaconda 4.2 prompt and in Pycharm, and using the basic Python 3.5 distribution.

我已为所涉及的所有内容授予管理员权限，并且我今天重新安装了所有软件，以便将其全部更新到最新版本.

I have given administrator privileges to everything involved and I reinstalled all of the software today so it is all updated to latest versions.

任何想法或帮助将不胜感激！

Any thoughts or help would be greatly appreciated!

# change this as you see fit
image_path = 'C:/moles'

# 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))

推荐答案

正确给出路径 /tf_files/retrained_labels.txt 到您的 retrained_labels.txt 路径和相同的更改对于 /tf_files/retrained_graph.pb

Give the path correctly /tf_files/retrained_labels.txt to your retrained_labels.txt path and same changes for /tf_files/retrained_graph.pb
