Windows Tensorflow 无法恢复检查点。 "Access is denied."

Question

我正在尝试运行 SSD-Tensorflow project using Tensorflow 1.1. When I try to restore the checkpoint file in cell 7 of ssd_notebook.ipynb 我收到以下错误：

Unable to open table file D:\Projects\SSD-Tensorflow\checkpoints\ssd_300_vgg.ckpt: Unknown: NewRandomAccessFile failed to Create/Open: D:\Projects\SSD-Tensorflow\checkpoints\ssd_300_vgg.ckpt : Access is denied. ; Input/output error [[Node: save_1/RestoreV2_70 = RestoreV2[dtypes=[DT_FLOAT], _device="/job:localhost/replica:0/task:0/cpu:0"](_recv_save_1/Const_0, save_1/RestoreV2_70/tensor_names, save_1/RestoreV2_70/shape_and_slices)]] [[Node: save_1/RestoreV2_31/_29 = _Recv[client_terminated=false, recv_device="/job:localhost/replica:0/task:0/gpu:0", send_device="/job:localhost/replica:0/task:0/cpu:0", send_device_incarnation=1, tensor_name="edge_421_save_1/RestoreV2_31", tensor_type=DT_FLOAT, _device="/job:localhost/replica:0/task:0/gpu:0"]()]]

本质上，

ckpt_filename = '../checkpoints/ssd_300_vgg.ckpt' saver = tf.train.Saver() session = tf.Session() saver.restore(session, ckpt_filename)

在尝试恢复检查点文件时抛出 Access Denied 错误。我确保我可以从该文件夹读取和写入，甚至尝试运行以管理员身份连接笔记本。

我以前也遇到过同样的问题，现在我找到问题所在了。我认为这是因为你没有把 save_path 弄对。以下是我做对的方法。希望对您有所帮助。

检查点文件包括两个文件：xxx.index 和 xxx.data。

函数saver.restore()中的变量save_path应该是'xxx'.

比如我把我的checkpoint保存在ckpt_path方向，一共有三个文件：

'model-20170508-212349.ckpt-17873.data-00000-of-00001'
'model-20170508-212349.ckpt-17873.index'
'model-20170508-212349.meta'

脚本应该是这样的：

saver.restore(session,'ckpt_path/model-20170508-212349.ckpt-17873')

Windows Tensorflow 无法恢复检查点。 "Access is denied."
