Question

我的代码是从tfrecord文件中读取图像

 Traceback (most recent call last):

错误消息

INSERT OR REPLACE INTO table () values();

我将所有图像和标签转换为tfrecord文件，并且必须在训练期间将文件转换为原始图像和标签。我正在尝试从tfrecords中读取图像，但弹出了outofrange错误。请任何人帮助如何解决此错误

Answer 1

OutOfRangeError因为未指定shapes而加注：

images, labels = tf.train.shuffle_batch([image, label], batch_size=10, capacity=30, num_threads=1, min_after_dequeue=10, shapes=[[224, 224, 1], []])

应该有用。
