Question

我正在尝试将我的数据（图像）转换为tfrecords。我是通过Stackoverflow进入此内置脚本的，但似乎无法正常工作。

https://github.com/tensorflow/models/blob/f87a58cd96d45de73c9a8330a06b2ab56749a7fa/research/inception/inception/data/build_image_data.py

我已更改默认标志值以反映我的值，例如：

tf.app.flags.DEFINE_string('train_directory', r'D:\project\Moondra\BAD_IMAGES\BAD IMAGES TRAINING DATA\TEST 2\training',
                           'Training data directory')
tf.app.flags.DEFINE_string('validation_directory', r''D:\project\Moondra\BAD_IMAGES\BAD IMAGES TRAINING DATA\TEST 2\validation',
                           'Validation data directory')
tf.app.flags.DEFINE_string('output_directory', r''D:\project\Moondra\BAD_IMAGES\BAD IMAGES TRAINING DATA\TEST 2\tfrecords',
                           'Output data directory')

tf.app.flags.DEFINE_integer('train_shards', 2,
                            'Number of shards in training TFRecord files.')
tf.app.flags.DEFINE_integer('validation_shards', 2,
                            'Number of shards in validation TFRecord files.')

tf.app.flags.DEFINE_integer('num_threads', 2,
                            'Number of threads to preprocess the images.')

tf.app.flags.DEFINE_string('labels_file','', r'D:\project\Moondra\BAD_IMAGES\BAD IMAGES TRAINING DATA\TEST 2\labels.txt')

training目录格式是5个子目录，每个子目录代表一个标签。

我尝试运行脚本，但是遇到以下错误：

Saving results to D:\project\Moondra\BAD_IMAGES\BAD IMAGES TRAINING DATA\TEST 2\tfrecords
Determining list of input files and labels from D:\project\Moondra\BAD_IMAGES\BAD IMAGES TRAINING DATA\TEST 2\validation.

; No such process

谢谢。

您是否验证了训练目录和验证目录都正确标记了数据？
标签也应与标签文件匹配。
最好从路径中删除空格。有时还会产生错误。 ;）

使用内置的初始脚本将图像目录转换为tfrecords
