用张量板

Question

运行具有张量流的NN模型，我想在训练集和测试集上绘制准确度分数。然而，情节张量板显示我看起来很奇怪：那里只有一个“准确性”标签，它在同一个数字上绘制了两个分数。所以基本上，x轴上的每一步都有两个连接在一起的点。如何在该图上分别绘制两条线（训练精度和测试精度）？

以下是我的代码片段：

loss_summary = tf.summary.scalar('loss', loss) acc_summary = tf.summary.scalar('accuracy', accuracy)

summary_loss, summary_acc_train = sess.run([loss_summary, acc_summary], feed_dict={X: X_train, y: y_train}) summary_acc_test = sess.run([acc_summary], feed_dict={X: X_test, y: y_test})

summary_writer.add_summary(summary_loss, epoch) summary_writer.add_summary(summary_acc_train, epoch) summary_writer.add_summary(summary_acc_test, epoch)

Answer 1

You need to create two different summary writers:

train_summary_writer = tf.summary.FileWriter(os.path.join(SUMMARIES_DIR, "train"), sess.graph)
validation_summary_writer = tf.summary.FileWriter(os.path.join(SUMMARIES_DIR, "validation"), sess.graph)

 ...

train_summary_writer.add_summary(summary_loss, epoch)
train_summary_writer.add_summary(summary_acc_train, epoch)
validation_summary_writer.add_summary(summary_acc_test, epoch)
