python - Tensorflow Windows Accessing Folders Denied:"NewRandomAccessFile failed to Create/Open: Access is denied. ; Input/output error"

Question

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.

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.

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

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))

Is C:/moles the name of an image file? The cause of the error appears to be that C:/moles is a folder, but you are trying to read it like a file. — mrry
Just you create moles directory in c drive and the error is solved. — Manivannan Murugavel

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