Question

我最近安装了Tensorflow for Windows。我正在尝试一个基本教程，我需要访问包含图像子文件夹的文件夹。

由于“访问被拒绝”，我无法访问图像文件夹。这在Anaconda 4.2提示符和Pycharm中都会发生，并使用基本的Python 3.5发行版。

我已经为所涉及的所有内容授予了管理员权限，我今天重新安装了所有软件，因此它已全部更新到最新版本。

任何想法或帮助将不胜感激！

# 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))

Answer 1

正确地将路径/tf_files/retrained_labels.txt提供给您的retrained_labels.txt路径以及/tf_files/retrained_graph.pb

的相同更改

Answer 2

我也面临着类似tensorflow的问题-除了以admin身份运行命令提示符外，我还被拒绝了权限，所以这就是我的解决方法-

确保python安装适用于PC上的所有用户如果不是，请尝试将python安装路径添加到PC的全局环境变量而非用户变量
以管理员身份运行命令提示符，输入命令-

网络用户管理员/ active：是“密码”

将密码替换为您要提供给管理员用户的密码

从重新启动菜单中，将用户切换为管理员，然后尝试使用python classify.py命令

应该可以让我知道是否有帮助

Tensorflow Windows访问文件夹被拒绝：“NewRandomAccessFile无法创建/打开：访问被拒绝。;输入/输出错误”
