在tensorflow服务中如何在python3中构建和运行客户端

Question

我希望能够在Py3中构建客户机，因为我有一些依赖关系。它建造得很好， 但是当我运行构建的二进制文件时，它抛出一个错误'undefined symbol: PyClass_Type'。这是一种 仅在py2c中可用，如前所述here。 自动生成_pywrap_tensorflow_internal.so文件。如何在Py3中构建和运行客户机？在

我在使用python3时也遇到了同样的错误，并且是从源代码处安装的。在

尝试用apt-get安装serving，用pip安装ModelServer https://www.tensorflow.org/serving/setup

pip install  upgrade tensorflow-serving-api-python3
sudo apt-get update && sudo apt-get install tensorflow-model-server
