【问题描述】：
我正在运行一个张量流模型，在 ml 引擎 上提交训练。我已经构建了一个 管道，它使用 tf.contrib.cloud.python.ops.bigquery_reader_ops.BigQueryReader 作为阅读器从 BigQuery 读取队列。
使用 DataLab 和在 local 中一切正常，将 GOOGLE_APPLICATION_CREDENTIALS 变量设置为指向凭证密钥的 json 文件。但是，当我在云中提交训练作业时，我收到了这些错误（我只发布了主要的两个）：
权限被拒绝：读取...的架构时出错（HTTP 响应代码 403，错误代码 0，错误消息“”）
创建模型时出错。检查详细信息：请求的身份验证范围不足。
我已经检查了其他所有内容，例如在脚本和项目/数据集/表 ID/名称中正确定义表架构
为了更清楚，我将日志中出现的整个错误粘贴在这里：

任何建议都会非常有帮助，因为我对 GC 比较陌生。 谢谢大家。
