python - 带有进程和错误的多处理：TypeError: can't pickle _thread.lock objects

问题描述

我只是无法进一步解决问题，我不明白为什么。我做多处理，这在一个小例子中也很有效。但是当我将它构建到“大”代码中时，它就不再起作用了。也许有人可以“更容易”地向我解释这个错误，或者告诉我我做错了什么？

self = reduction.pickle.load(from_parent)
EOFError: Ran out of input

发生错误的代码：

nodesAdh = multiprocessing.Process(target=myScarfMeshR3D.generateAdhesiveNodesObject, args=(_sectionAdh,))
        nodesAdh.start()
