我正在尝试使用TensorFlow服务和gRPC调用部署在 Cloud 代工服务器上的TensorFlow模型，该服务器使用Python 2.7 API . 该模型需要200 dim向量作为输入，我现在硬编码 . 连接变量存储在virtualenv中并检查两次 .
代码：
import os

import tensorflow as tf
from tensorflow_serving.apis import predict_pb2
from tensorflow_serving.apis import prediction_service_pb2
from grpc._cython import cygrpc
MODEL_NAME = str(os.getenv('MODEL_NAME', ''))
MODEL_SERVER_HOST = str(os.getenv('MODEL_SERVER_HOST', ''))
MODEL_SERVER_PORT = int(os.getenv('MODEL_SERVER_PORT', ''))
ROOT_CERT = str(os.getenv('ROOT_CERT', '')).replace('\\n', '\n')
def metadata_transformer(metadata):
additions = []
token = 'Bearer <my access token>'
additions.append(('authorization', token))
return tuple(metadata) + tuple(additions)
credentials = implementations.ssl_channel_credentials(root_certificates=ROOT_CERT)
channel = implementations.secure_channel(MODEL_SERVER_HOST, MODEL_SERVER_PORT, credentials)
stub = prediction_service_pb2.beta_create_PredictionService_stub(channel, metadata_transformer=metadata_transformer)
