在Oracle云基础设施中，如何将笔记本中生成的csv文件直接上传到存储桶中？

Question

在我的笔记本中，我从数据帧生成了一个 .csv 文件，现在我想将其上传到我的存储桶中。我怎样才能做到这一点？ 到目前为止，我只能生成 .csv，它出现在屏幕左上角的文件列表中；我必须点击下载它，在 OCI 中打开我的存储桶并手动上传文件。我想要笔记本将其直接上传到存储桶中。如果有从存储桶读取文件的代码，我认为也可以将其上传到存储桶。

我尝试运行Oracle团队提供的这段代码：

但是我得到了这个： ConfigFileNotFound：无法在 /home/datascience/.oci/config 找到配置文件，请按照链接中的说明设置配置文件 https://docs.cloud.oracle.com/en-us/iaas/Content /API/Concepts/sdkconfig.htm

我什至不知道上面的代码中到底要替换什么。从存储桶中读取文件的代码要简单得多。

Answer 1

您的代码失败于

config = oci.config.from_file()

因为您的本地系统缺少 OCI 配置文件 (~/.oci/config) 来进行身份验证。你在哪里运行这个脚本？请使用this链接来设置oci配置文件。
