Tensorflow 调试'；TypeError：无法将数据数组转换为张量或运算'；美国有线电视新闻网

我正在尝试建立一个CNN，我在输入样本中有8个类，每个类中有45个样本。所以输入样本的总数是360。我已将前20个样本划分为训练样本，其余25个样本作为每个类的测试样本（我的输入是一个文本文件，行中的数据是我的预处理数据，因此我正在读取文本文件中的行，并重塑16x12大小的图像）

我无法修复代码中的错误

文件可以下载，Session.run只接受张量或张量名称的列表

imgs, lbls = sess.run([image_batch_test, label_batch_test])

在前一行中，您正在通过

image\u batch\u test

和

label\u batch\u test

，这两个数组都是numpy数组。我不确定您试图通过

imgs，lbls=sess.run（[image\u batch\u test，label\u batch\u test]）
