Grow, water, prune your behaviour tree with this, the tree custodian. It features a few enhancements that go above and beyond just ticking the root behaviour of a tree. These provide richer logging, introspection and dynamic management of the tree itself: The py-trees-demo-tree-stewardship program demonstrates the above features.

2025年1月13日 · PyTrees is a Python implementation of behaviour trees designed to facilitate the rapid development of medium sized decision making engines for use in fields like robotics. Brief feature list: Behaviours, Decorators, Sequences, Selectors, Parallels and BehaviourTree. Blackboards for data sharing.

pyC45 is a super light C4.5 decision tree package for python which contains only one file “pyC45.py”. It provides the user a simple and efficient interface to train a C4.5 decision tree and use it to do predictions or classifications. The trained decision tree is saved as an XML file so that it can be read and easily understood.

Blackboards are not a necessary component of behaviour tree implementations, but are nonetheless, a fairly common mechanism for sharing data between behaviours in the tree. See, for example, the design notes for blackboards in Unreal Engine. Implementations vary widely depending on the needs of the framework using them.

常见的行为树(bt)框架有C++版本的BehaviorTree.CPP库，和python版本的py_tree库。 看个人喜好，因为我工作中写逻辑框架的时候需要 快速 实现并且可视化下框架结构后用于小组讨论，所以我在项目的初期甚至整个项目中也都是使用 py _ tree .........

2023年1月3日 · 文章详细介绍了Pythonpyc文件的生成过程，包括import如何触发pyc生成，pyc文件的内容结构，如magicnumber、时间戳、文件大小和PyCodeObject。同时，文章展示了如何手动构建PyCodeObject并生成pyc文件，以及探讨了字节码混淆作为源代码保护的一种手段。

JAX中的pytree指的是使用python容器（比如list、dict、tuple、OrderedDict、None、namedtuple等）储存的树状结构的数据（e.g., lists of lists of dicts）。 如果一些数据没有被python容器装起来，那么它就是子叶数据（比如数值、数组、类、字符串），pytree中可以嵌套pytree。 （大白话：就是嵌套式的list/dict/tuple结构） 比如这里举三个例子： 可视化：显示出子叶的位置。 用的最多的api是jax.tree_map和jax.tree_multimap。

2023年5月28日 · createPlot (mytree)方法实现。 其中myTree是一个字典，调用retrieveTree (0)可以获得一个字典的样式。 plotTree.totalD = float(getTreeDepth(inTree)) plotTree.xOff = -0.5/plotTree.totalW; plotTree.yOff = 1.0; plotTree(inTree, (0.5,1.0), '') plt.show() fig = plt.figure(1, facecolor='white') fig.clf() createPlot.ax1 = plt.subplot(111, frameon=False) #ticks …
