colab读取google cloud storage

可以通过以下代码读取Google Cloud Storage的数据：

from google.cloud import storage

# Replace the values with your project ID and credentials file path
project_id = 'your_project_id'
key_file_path = 'path_to_your_service_account_key_file.json'

# Set the Google Cloud Storage bucket name and file name
bucket_name = 'your_bucket_name'
file_name = 'your_file_name'

# Authenticate and initialize the client
client = storage.Client(project=project_id, credentials=credentials)

# Get the bucket and file objects
bucket = client.get_bucket(bucket_name)
blob = bucket.blob(file_name)

# Download the file to a local directory
blob.download_to_filename('/path/to/your/local/directory')

注意：要成功运行以上代码，你需要先在Google Cloud Console中创建一个存储桶，然后在Colab中安装必要的Google Cloud SDK并授权访问权限。
