Question

我正在尝试使用以下代码行从Colab访问GCS并得到给定的错误。我想念什么吗？还是Colab不支持这种GCS访问？我可以使用任何解决方法或最佳做法吗？

from google.cloud import storage

client = storage.Client()
bucket = client.get_bucket('busnet_videos')
blob = bucket.blob('my-test-file.txt')
blob.upload_from_string('this is test content!')

错误：

    ---------------------------------------------------------------------------

OSError                                   Traceback (most recent call last)

     10 bucket = client.get_bucket('busnet_videos')
     11 blob = bucket.blob('my-test-file.txt')

OSError: Project was not passed and could not be determined from the environment.

您可能必须设置一个环境变量：

GOOGLE_APPLICATION_CREDENTIALS=SERVICE_ACCOUNT_KEY.json

和

PROJECT_ID=YOUR_GOOGLE_CLOUD_PROJECT_ID

来自colab的GCS Python访问
