Apparently this is coming from trying to pickle https://github.com/apache/tvm/blob/c97895e0ffb512e73c89de7cdee9846f052244fc/python/tvm/contrib/hexagon/build.py#L614. The question is, can we remove `_server_process` from `HexagonLauncherSimulator`? -- This is an automated message from the Apache Git Service.
