TypeError：传递给参数'input'的值的DataType字符串不在允许值列表中：int32，int64，complex64，float32，float64，bool，int8

我试图使用tensorflow . 输入属性类似于 census 示例，但LABEL列是连续值 . 我执行了以下命令：

test-server＃：〜/ aaaml-samples / arbitrator $ gcloud ml-engine local train --module-name trainer.task --package-path trainer / --train-files $ TRAIN_DATA --eval-files $ EVAL_DATA --train-steps 1000 --job-dir $ MODEL_DIR

对tensorflow来说是新手 . 我知道在处理评估文件（aaa.test.csv）时会出现此问题 . 正确定义评估文件数据和格式 . 并且列数据类型也已正确映射 . 但我不确定错误发生的原因 .
