我正试图将SavedModel格式的tensorflow模型从我的谷歌云存储桶加载到我的云函数中。我正在使用此教程：https://cloud.google.com/blog/products/ai-machine-learning/how-to-serve-deep-learning-models-using-tensorflow-2-0-with-cloud-functions
cloud函数编译正确。然而，当我向云功能发送http请求时，它会给出以下错误：

我很困惑，因为我的水桶的标题是一个大约20个字符长的字母串，没有任何标点符号/特殊字符。
这是我正在运行的一些代码：
if model is None:
download_blob('<terminatorbucket>', 'firstModel/saved_model.pb', '/tmp/model/saved_model.pb')
download_blob('<terminatorbucket>', 'firstModel/assets/tokens.txt', '/tmp/model/assets/tokens.txt')
download_blob('<terminatorbucket>', 'firstModel/variables/variables.index', '/tmp/model/variables/variables.index')
download_blob('<terminatorbucket>', 'firstModel/variables/variables.data-00000-of-00001', '/tmp/model/variables/variables.data-00000-of-00001')
model = tf.keras.models.load_model('/tmp/model')
def download_blob(bucket_name, source_blob_name, destination_file_name):
"""Downloads a blob from the bucket."""
storage_client = storage.Client()
bucket = storage_client.get_bucket(bucket_name)
blob = bucket.blob(source_blob_name)
blob.download_to_filename(destination_file_name)
错误消息抱怨bucket名称中有尖括号，这些尖括号不被视为数字或字母。确保您的bucket名称与您在云控制台中看到的名称完全相同。
