Question

我正在尝试将一组jpg图像转换为TFRecord，以便与Tensorflow中的CNN一起使用。我从这里使用脚本build_image_data.py：

https://github.com/tensorflow/models/blob/master/inception/inception/data/build_image_data.py

我已经创建了一个验证目录和一个培训目录以及带有相应标签的labels.txt文件。我使用jupyter notebook运行脚本（我也尝试过命令行），我已将tf.app.flags.DEFINE_string参数更改为相应的目录/文件名。当我运行它时，我收到以下错误：

[x+y | x <- list1, y <- list2, x != y]

任何线索？我正在从包含我的验证和培训文件夹的同一目录运行脚本。谢谢。

编辑：尝试使用完整路径但仍然出现相同的错误。这是代码的相关部分，我确信这是我的一些简单错误。

Answer 1

您应该将地址放在/ temp /

的位置

tf.app.flags.DEFINE_string('train_directory', 'D:/full/path',
                       'Training data directory')

不确定为什么我的buildforimage_data.py脚本不能正常工作
