要解决BigQuery ML无法识别数据中的标签列的问题,可以尝试以下解决方法:
确保标签列的数据类型正确:
示例代码:
SELECT
feature1, feature2, feature3,
CAST(label_column AS INT64) AS label
FROM
dataset.table
确保标签列的名称正确:
示例代码:
SELECT
feature1, feature2, feature3,
label_column AS label
FROM
dataset.table
确保标签列的值是有效的:
示例代码:
SELECT
feature1, feature2, feature3, label_column
FROM
dataset.table
WHERE
label_column IS NOT NULL
AND label_column != ''
确保标签列的位置正确:
示例代码:
SELECT
feature1, feature2, label_column, feature3
FROM
dataset.table
如果以上方法仍无法解决问题,可能需要进一步检查数据集和查询语句,确保没有其他错误或问题。
