Question

我希望能够在Py3中构建客户端，因为我有一些依赖项。它建立很好，但是当我运行构建的二进制文件时，它会抛出错误'undefined symbol: PyClass_Type'。这是一种类型仅在Py2 C中可用，如here所述。自动生成_pywrap_tensorflow_internal.so文件。如何在Py3中构建和运行客户端？

我使用python3得到了同样的错误并从源代码安装。

尝试通过pip安装apt-get和ModelServer的服务 https://www.tensorflow.org/serving/setup

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

如何在tensorflow服务
