请问我编译后build下找不到python_wrapper

[JunyuanDeng]

一般来说，编译后是可以找到的。可能是你编译过程出错了，如果您能提供更多编译时的信息或者其他信息，我能更清楚定位到问题。

看上去已经装好了，你有运行过pip install . 吗？

[iason-r]

运行了，我分别尝试了先c++编译再python编译和先python编译再c++编译，结果都是没有在build下生成python_wrapper，编译过程也没有错误，您能和我讲解一下这个文件的作用嘛

[JunyuanDeng]

主要是因为原来是用c++写的，用python调用的话，就需要这么一个接口，里面有一个.so文件。如果您能运行pip install .我猜测他已经装在了你系统里面了，你可以看看能不能运行他里面的demo，python版本的。如果可以的话，那就不需要patchwork_module_path 了

[iason-r]

恩恩，是这样的，谢谢您啦
