在 Colab 启动地球引擎项目

Question

我无法再使用 Python 在 Google

colab

上初始化我自己的地球引擎项目。

我尝试使用 Colab 上的

ee.Initialize()

方法进行初始化，用于提供一个链接，该链接将为我的项目生成令牌，但我收到此错误：

WARNING:googleapiclient.http:Encountered 403 Forbidden with reason "PERMISSION_DENIED"

    384   except googleapiclient.errors.HttpError as e:

Answer 1

他们缺乏有关此更改的文档，这令人非常沮丧，但幸运的是，这是一个非常简单的修复（或者至少对我来说）。

如果您转到 Earth 引擎代码编辑器并单击“资产”选项卡，然后复制您要访问的所有 EE 资产的项目名称。

然后，在 Colab 脚本的初始化步骤中，将 'ee.Initialize()' 替换为 'ee.Initiliaze(project='NameofYourEarthEngineProject')

希望这有帮助。

还提供了解决方案这里

它涉及进入您的 Google Cloud 帐户并显式激活 GEE api，然后创建一个新项目，您最终在调用 ee.Initialize() 时指定该项目。这样做的好处是，当您从 Colab 调用 GEE 时，您不再需要通过一系列复杂的点击和链接来获取令牌，它只是运行并激活。一开始会令人沮丧，但从长远来看，这可以节省时间。
