【问题描述】:
我正在尝试修改此代码(请参阅下面的 GitHub 链接),以便我可以使用自己的数据并使用同一组功能预测多个标签。
当我一次使用一个标签时,它可以正常工作。但是,当我尝试创建一个包含多个标签的张量时,我遇到了问题。有什么建议吗?
我修改后的 LABELS 和 input_fn 如下所示:
LABELS = ["Label1", "Label2", "Label3"]
def input_fn(data_set):
feature_cols = {k: tf.constant(len(data_set), shape=[data_set[k].size, 1]) for k in FEATURES}
labels_data = []
for i in range(0, len(data_set)):
temp = []
for label in LABELS:
temp.append(data_set[label].values[i])
labels_data.append(temp)
labels = tf.constant(labels_data, shape=[len(data_set), len(LABELS)])
return feature_cols, labels
这是我收到的错误消息的结尾:
