前言（Introduction）

GraphExecuter 是一款基于 NodeGraphQt 开发的开源软件，采用 多线程图执行 架构，用户只需编写节点逻辑并通过连线构建图，即可自动调度并运行复杂的工作流。

该系统结合了 可视化节点编辑 和 高效并行计算，适用于数据处理、自动化任务、分布式计算等场景。开发者无需关心线程管理，只需专注于节点功能的实现，即可快速搭建高性能工作流。GraphExecuter 为需要 灵活、可扩展、可视化编排 的用户提供了便捷的解决方案，适用于从实验到生产的各种需求。

GraphExecuter is an open-source software built on NodeGraphQt, designed to simplify complex workflow execution through a node-based graph system. By utilizing multi-threading, it efficiently processes connected nodes, allowing users to focus on defining individual node logic while the framework handles task scheduling and parallel execution.

With an intuitive node-based interface, users can easily design, connect, and execute workflows for tasks like data processing, automation, or distributed computing. GraphExecuter is ideal for developers and researchers who need a flexible, visual, and high-performance way to manage complex workflows without dealing with low-level concurrency control.

开发环境搭建（Development environment setup）

pip install -r .\requirements.txt

## 强制重新安装模块
pip install --force-reinstall --no-cache-dir pyside6

运行（Run test）

python main.py

❇️创建节点

❇️连接节点

❇️从选中节点开始运行图

开发者（Developer）

❇️编写节点（Create node type）

❇️注册节点（Register node type）

编译（Compile）

./compile.bat

生成的可执行文件存放在dist文件夹下

报错

❌框选节点的时候报错

Error calling Python override of QGraphicsView::mouseMoveEvent(): Traceback (most recent call last):
  File "D:\ProgramData\anaconda3\envs\DataProcessUI\Lib\site-packages\NodeGraphQt\widgets\viewer.py", line 619, in mouseMoveEvent
    self.scene().setSelectionArea(
TypeError: 'PySide6.QtWidgets.QGraphicsScene.setSelectionArea' called with wrong argument types:
  PySide6.QtWidgets.QGraphicsScene.setSelectionArea(QPainterPath, ItemSelectionMode)
Supported signatures:
  PySide6.QtWidgets.QGraphicsScene.setSelectionArea(path: PySide6.QtGui.QPainterPath, /, selectionOperation: PySide6.QtCore.Qt.ItemSelectionOperation = Instance(Qt.ReplaceSelection), mode: PySide6.QtCore.Qt.ItemSelectionMode = Instance(Qt.IntersectsItemShape), deviceTransform: PySide6.QtGui.QTransform = Default(QTransform))
  PySide6.QtWidgets.QGraphicsScene.setSelectionArea(path: PySide6.QtGui.QPainterPath, deviceTransform: PySide6.QtGui.QTransform, /)

✔️Pyside6和nodegraphqt版本不适配导致，更改viewer.py以下位置即可：

# "D:\ProgramData\anaconda3\envs\XXXXXXXX\Lib\site-packages\NodeGraphQt\widgets\viewer.py"

# self.scene().setSelectionArea(
#     path, QtCore.Qt.IntersectsItemShape
# )
self.scene().setSelectionArea(
    path,
    selectionOperation=QtCore.Qt.ItemSelectionOperation.ReplaceSelection,
    mode=QtCore.Qt.ItemSelectionMode.IntersectsItemShape
)
