I think the problem is: label = parsed_line[-1:] # Last element is the label

should be label = parsed_line[-1] # Last element is the label

hi guys, I meet the same problem, can u help me? Thx! TensorFlow version is 1.8 my code is :

def decode_csv(line):
    parsed_line = tf.decode_csv(line, [[0.], [0.], [0.], [0.], [0]])
    return {'x': parsed_line[:-1]}, parsed_line[-1]

dataset = tf.data.TextLineDataset(file_path).skip(1).map(decode_csv)

the errors:
