我是Tensorflow的新手，请帮助修复此错误。我使用Tensorflow教程代码使用get_input_fn将pandas数据帧输入转换为张量，但我遇到了这个错误。没什么好帮助会很感激。

这是我对pandas dataframe的get_input_fn（）。
def get_input_fn(data, num_epochs = None, shuffle = True):
features = ['name', 'ship', 'GC', 'SC1_Enc', 'SC2_Enc', 'rating', 'condition', 'pol']
label = ['target']
return tf.estimator.inputs.pandas_input_fn(
x = {k: tf.constant(data[k].values) for k in features},
y = tf.constant(data[label].values),
num_epochs = num_epochs,
shuffle = shuffle)
