Question

我正在遵循TensorFlow Mechanics 101（版本0.7.0）的教程。根据文档，我下载了两个文件（mnist.py和fully_connected_feed.py）并将它们保存到本地计算机上的同一目录中。

当我运行以下命令时：

$ python /FULL_PATH_TO_fully_connected_feed.py/fully_connected_feed.py

...我收到此错误：OSError: [Errno 2] No such file or directory: ''。完整输出和堆栈跟踪如下：

...

Step 900: loss = 0.51 (0.004 sec)

Answer 1

这是TensorFlow的0.7.0版本中的一个错误，该错误已在a recent commit中修复，并将很快出现在错误修正版本中。当--train_dir标志不包含目录名称组件时，会导致该问题。

与此同时，您可以在运行示例时传递标记--train_dir=./来避免此问题。

Answer 2

这应该是对mrry帖子的评论（我缺少声望）

将第42行从fully_connected_feed.py更改为

flags.DEFINE_string('train_dir', './data', 'Directory to put the training data.')

为我解决了这个问题。我也是0.7.0并且能够运行所有其他mnist示例。

无法在Tensorflow中运行fully_connected_feed.py
