+## 概述
+
+本文档完整说明 **ComfyUI-QwenImageLoraLoader** 中 Nunchaku Qwen Image LoRA Stack V1 节点的实现,以及 V4 到 V1 的重命名变更。对应 GitHub 发行 [v2.4.0](https://github.com/ussoewwin/ComfyUI-QwenImageLoraLoader/releases/tag/v2.4.0) 的英文说明:
+
+**v2.4.0 完整修改说明:V4 到 V1 重命名与 Nunchaku Qwen Image LoRA Stack V1**
+
+**致谢**:Nunchaku Qwen Image LoRA Stack V1 节点(rgthree 风格 UI)由 [@avan06](https://github.com/avan06) 通过 [PR #49](https://github.com/ussoewwin/ComfyUI-QwenImageLoraLoader/pull/49) 贡献。本文档解释已合并的贡献内容、V4→V1 重命名以及实现细节。
+
+---
+
+## 1. 节点功能概述
+
+### 1.1 此节点的作用
+
+**Nunchaku Qwen Image LoRA Stack V1** 节点可在单个节点中将多个 LoRA(低秩适配)权重应用于 Nunchaku Qwen Image 扩散模型。与单 LoRA 加载器不同,此节点允许用户堆叠多个 LoRA,并为每个 LoRA 单独控制强度。
+
+**主要功能**:
+- 在一个节点中应用多个 LoRA(动态行数)
+- 每个 LoRA 的启用/禁用切换
+- 每个 LoRA 的强度调整(0.00–2.00,步进 0.05)
+- 总开关(`stack_enabled`)用于禁用整个堆栈
+- CPU 卸载控制(auto/enable/disable)
+- AWQ 调制层支持(`apply_awq_mod`)用于量化模型
+- 工作流序列化(保存的工作流保留 LoRA 配置)
+
+**UI 设计**:受 [Power Lora Loader (rgthree-comfy)](https://github.com/rgthree/rgthree-comfy) 启发的 rgthree 风格紧凑布局。每个 LoRA 行显示:切换开关 | LoRA 名称 | ◀ 强度 ▶ 于单个水平栏中。
+
+**限制**:无法与 ComfyUI Nodes 2.0 正常配合。请使用标准(LiteGraph)画布。
+
+---
+
+## 2. Python 后端:完整代码与说明
+
+**文件**:`nodes/lora/qwenimage_v1.py`
+
+### 2.1 导入与路径设置(第 1–30 行)
+
+```python
+"""
+This module provides the :class:`NunchakuQwenImageLoraStackV1` node
+for applying LoRA weights to Nunchaku Qwen Image models within ComfyUI.
+The interface completely mimics the Power Lora Loader from rgthree-comfy(https://github.com/rgthree/rgthree-comfy ),
+supporting dynamic additions and custom widgets.
+"""
+
+import copy
+import logging
+import os
+import sys
+
+# Fix import path for this module
+current_dir = os.path.dirname(os.path.abspath(__file__))
+# Go up 2 levels: nodes/lora -> nodes -> ComfyUI-QwenImageLoraLoader
+lora_loader_dir = os.path.dirname(os.path.dirname(current_dir))
+if lora_loader_dir not in sys.path:
+ sys.path.insert(0, lora_loader_dir)
+ print(f"[DEBUG] Added to sys.path: {lora_loader_dir}")
+ print(f"[DEBUG] wrappers dir exists: {os.path.exists(os.path.join(lora_loader_dir, 'wrappers'))}")
+ print(f"[DEBUG] qwenimage.py exists: {os.path.exists(os.path.join(lora_loader_dir, 'wrappers', 'qwenimage.py'))}")
+
+import folder_paths
+
+# Get log level from environment variable (default to INFO)
+log_level = os.getenv("LOG_LEVEL", "INFO").upper()
+
+# Configure logging
+logging.basicConfig(level=getattr(logging, log_level, logging.INFO), format="%(asctime)s - %(levelname)s - %(message)s")
+logger = logging.getLogger(__name__)
+```
+
+**说明**:
+- `copy`:用于 `copy.deepcopy(model)`,在添加 LoRA 时克隆模型。
+- `lora_loader_dir`:解析 ComfyUI-QwenImageLoraLoader 根目录,以便能够导入 `wrappers.qwenimage`。ComfyUI 自定义节点可能未将父目录加入 `sys.path`。
+- `folder_paths`:ComfyUI 模块,用于解析模型/LoRA 路径(例如 `folder_paths.get_full_path_or_raise("loras", lora_name)`)。
+- `logger`:用于状态和调试输出。
+
+---
+
+### 2.2 FlexibleOptionalInputType 与 any_type(第 32–40 行)
+
+```python
+class any_type(str):
+ def __ne__(self, __value: object) -> bool:
+ return False
+
+class FlexibleOptionalInputType(dict):
+ def __contains__(self, key):
+ return True
+ def __getitem__(self, key):
+ return (any_type, {})
+```
+
+**说明**:
+- ComfyUI 使用 `key in optional` 和 `optional[key]` 验证输入类型。默认情况下,仅接受已声明的可选输入。
+- `FlexibleOptionalInputType` 使**任何**键都表现为有效的可选输入:`__contains__` 始终返回 `True`,`__getitem__` 返回 `(any_type, {})`。
+- `any_type` 是字符串子类,其 `!=` 始终返回 `False`,因此在验证期间匹配任何类型。
+- **目的**:JS 前端在运行时添加动态控件 `lora_1`、`lora_2`、…。Python 节点事先不知道它们的名称。通过声明 `"optional": FlexibleOptionalInputType()`,从前端传入的任何 `lora_N` 键都会被接受,并通过 `**kwargs` 转发给 `load_lora_stack`。
+
+---
+
+### 2.3 RETURN_TYPES、FUNCTION 与元数据(第 88–94 行)
+
+```python
+ RETURN_TYPES = ("MODEL",)
+ OUTPUT_TOOLTIPS = ("The modified diffusion model with all LoRAs applied.",)
+ FUNCTION = "load_lora_stack"
+ TITLE = "Nunchaku Qwen Image LoRA Stack V1"
+ CATEGORY = "Nunchaku"
+ DESCRIPTION = "Apply multiple LoRAs to a diffusion model in a single node with dynamic UI control."
+```
+
+**说明**:
+- `RETURN_TYPES`:节点返回单个 `MODEL` 输出。
+- `FUNCTION`:节点运行时调用的方法。
+- `TITLE` / `CATEGORY` / `DESCRIPTION`:ComfyUI 节点浏览器和工具提示元数据。
+
+---
+
+### 2.4 节点类与 INPUT_TYPES(第 42–86 行)
+
+```python
+class NunchakuQwenImageLoraStackV1:
+ """
+ Node for loading and applying multiple LoRAs to a Nunchaku Qwen Image model with dynamic UI.
+ Built upon V3, pays full homage to the clean and minimalist design of the

+ """
+
+ @classmethod
+ def INPUT_TYPES(s):
+ inputs = {
+ "required": {
+ "model": (
+ "MODEL",
+ {"tooltip": "The diffusion model to apply LoRAs to."},
+ ),
+ "cpu_offload": (
+ ["auto", "enable", "disable"],
+ {
+ "default": "disable",
+ "tooltip": "CPU offload setting. 'auto' enables offload when VRAM is low, 'enable' forces offload, 'disable' disables offload.",
+ },
+ ),
+ "apply_awq_mod": (
+ "BOOLEAN",
+ {
+ "default": True,
+ "tooltip": "Enable manual planar injection for AWQ modulation layers. Fixes noise issues in quantized models. Default is True.",

+ # Use 'hidden' here to let JS pass dynamic LoRA data
+ "hidden": {
+ "prompt": "PROMPT",
+ "extra_pnginfo": "EXTRA_PNGINFO",
+ },
+ }
+
+ return inputs
+```
+
+**说明**:
+- `model`:来自 Nunchaku Qwen Image DiT Loader 的输入扩散模型。
+- `cpu_offload`:控制当 VRAM 较低时模型是否在 CPU 上运行。
+- `apply_awq_mod`:为 AWQ 量化调制层启用手动平面注入;修复量化模型的噪声问题。
+- `stack_enabled`:总开关;当为 `False` 时,无论每行的切换状态如何,都不应用任何 LoRA。
+- `optional`:接受来自前端的任何动态 `lora_N` 输入。
+- `hidden`:ComfyUI 标准;`prompt` 和 `extra_pnginfo` 用于工作流序列化。
+
+---
+
+### 2.5 load_lora_stack — 第 1 部分:解析动态 LoRA 数据(第 95–144 行)
+
+```python
+ def load_lora_stack(self, model, cpu_offload="disable", apply_awq_mod=True, stack_enabled=True, **kwargs):
+ # Dynamic widgets passed from JS will appear in kwargs
+ # Named lora_1, lora_2... with values as dictionaries: {'enabled': bool, 'lora_name': str, 'lora_strength': float}

+
+ if not loras_to_apply:
+ return (model,)
+```
+
+**说明**:
+- `kwargs` 包含来自 JS 控件的 `lora_1`、`lora_2`、…。每个值都是 `{enabled, lora_name, lora_strength}`。
+- `lora_keys` 按数字后缀排序,因此按顺序处理各行。
+- 对于每个槽位:
+ - 仅当 `stack_enabled` 和该行的 `enabled` 均为 `True` 时,`enabled` 才为 `True`。
+ - 仅在以下条件下应用 LoRA:`enabled`、已设置 `lora_name`(不是 `"None"`)、且 `abs(lora_strength) > 1e-5`。
+- 如果没有 LoRA 符合条件,则原样返回模型。
+

+
+### 2.6 load_lora_stack — 第 2 部分:模型包装与 ComfyQwenImageWrapper(第 146–211 行)
+
+```python
+ model_wrapper = model.model.diffusion_model
+
+ # Dynamic import with explicit path manipulation
+ import importlib.util
+
+ lora_loader_dir = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))

+ if hasattr(model_wrapper, "apply_awq_mod") and model_wrapper.apply_awq_mod != apply_awq_mod:
+ model_wrapper.apply_awq_mod = apply_awq_mod
+ transformer = model_wrapper.model
+ elif model_wrapper_type_name == "NunchakuQwenImageTransformer2DModel" or model_wrapper_type_name.endswith(

+ logger.error("Please use 'Nunchaku Qwen Image DiT Loader'.")
+ raise TypeError(f"This LoRA loader only works with Nunchaku Qwen Image models, but got {model_wrapper_type_name}.")
+```
+
+**说明**:
+- `model.model.diffusion_model` 是实际的 transformer(例如 `NunchakuQwenImageTransformer2DModel`)。
+- 如果已经被包装(存在 `model` 和 `loras` 属性),则仅更新 `cpu_offload` 和 `apply_awq_mod`。
+- 否则,使用 `ComfyQwenImageWrapper` 进行包装,该包装器:
+ - 保存 `(path, strength)` 元组的 `loras` 列表。
+ - 在模型运行时通过 `compose_loras_v2` 将 LoRA 组合到模型中。
+- 此节点仅适用于 Nunchaku Qwen Image 模型;其他类型会引发 `TypeError`。
+

+
+### 2.7 load_lora_stack — 第 3 部分:Flux 风格深拷贝与 LoRA 追加(第 212–237 行)
+
+```python
+ # Flux-style deepcopy
+ saved_config = None
+ if hasattr(model, "model") and hasattr(model.model, "model_config"):
+ saved_config = model.model.model_config
+ model.model.model_config = None
+
+ model_wrapper.model = None
+ try:

+
+ logger.info(f"Total LoRAs in stack: {len(ret_model_wrapper.loras)}")
+ return (ret_model,)
+```
+
+**说明**:
+- ComfyUI 期望每个节点返回一个*新*的模型对象。不得修改原始对象。
+- 在 `deepcopy` 之前清除 `model_config`,因为它可能包含不可 pickle 的数据。之后将其恢复。
+- `model_wrapper.model` 被临时设为 `None`,以便不深度拷贝 transformer;仅拷贝包装器结构。
+- 在 `deepcopy` 之后,`ret_model_wrapper` 接收拷贝的 `loras` 列表,并将此节点的新 LoRA 追加进去。
+- `folder_paths.get_full_path_or_raise("loras", lora_name)` 解析 LoRA 文件路径,如果找不到则引发错误。

+});
+
+const WIDGET_HEIGHT = 24;
+const HORIZ_MARGIN = 15;
+```
+
+**说明**:
+- `app`:ComfyUI 应用;用于 `app.canvas.prompt`、`app.registerExtension`。
+- `api`:用于 `api.fetchApi("/object_info")` 获取 LoRA 列表。
+- `getColors()`:返回主题感知颜色,使控件在亮模式和暗模式下均显示正确。
+- `WIDGET_HEIGHT`、`HORIZ_MARGIN`:每个 LoRA 行的布局常量。

+ strengthDec: [0, 0],
+ strengthInc: [0, 0],
+ strengthVal: [0, 0]
+ };
+ }
+```
+
+**说明**:
+- `name`:例如 `lora_1`、`lora_2`;必须与 Python 在 `kwargs` 中预期的名称匹配。
+- `type: "custom"`:ComfyUI/LiteGraph 自定义控件;需要 `draw` 以及可选的 `mouse`、`serializeValue`。
+- `value`:发送给后端的状态:`{enabled, lora_name, lora_strength}`。
+- `last_y`:该行的垂直位置;用于右键点击命中测试。
+- `hitAreas`:每个交互区域(切换开关、LoRA 名称、◀、值、▶)的 `[xMin, xMax]`。在 `draw` 中更新,在 `mouse` 中使用。

+
+**说明**:
+- 仅左键点击;右键保留给节点的插槽菜单。
+- 如果 `stack_enabled` 关闭,则无交互。
+- 使用 `hitAreas` 决定:切换、LoRA 选择器、减量、增量或数字提示。
+- 强度由 UI 隐式限制;提示允许任何浮点数。

+### 3.5 chooseLora 与 serializeValue(第 158–176 行)
+
+```javascript
+ async chooseLora(event) {
+ const resp = await api.fetchApi("/object_info");
+ const data = await resp.json();
+ const loras = data?.LoraLoader?.input?.required?.lora_name?.[0] || [];
+
+ new LiteGraph.ContextMenu(loras, {
+ event: event,
+ callback: (value) => {
+ this.value.lora_name = value;
+ this.parentNode.setDirtyCanvas(true, true);
+ }
+ });
+ }
+
+ serializeValue() {
+ return this.value;
+ }
+```
+
+**说明**:
+- `chooseLora`:从 `/object_info` 获取 LoRA 列表,显示上下文菜单,在选择时更新 `lora_name`。
+- `serializeValue`:返回 `{enabled, lora_name, lora_strength}`,以便 ComfyUI 将其包含在发送给后端的 prompt 中。
+
+---
+
+### 3.6 扩展注册与 beforeRegisterNodeDef(第 178–214 行)
+
+```javascript
+app.registerExtension({
+ name: "nunchaku.qwen_lora_dynamic_v1",
+
+ async beforeRegisterNodeDef(nodeType, nodeData, app) {
+ if (nodeData.name !== "NunchakuQwenImageLoraStackV1") return;
+
+ const onNodeCreated = nodeType.prototype.onNodeCreated;
+ nodeType.prototype.onNodeCreated = function () {

+ this.serialize_widgets = true;
+ this.loraWidgets = [];
+
+ const stackEnabledWidget = this.widgets.find(w => w.name === "stack_enabled");
+ if (stackEnabledWidget) {
+ stackEnabledWidget.callback = () => { this.setDirtyCanvas(true); };
+ }
+
+ const btn = this.addWidget("button", "➕ Add Lora", null, (val, canvas, node, pos, event) => {
+ this.addLoraRowWithChooser(event);
+ });
+ btn.serialize = false;
+
+ const HEADER_H = 60, INPUT_WIDGETS_H = stackEnabledWidget ? 50 : 0, PADDING = 20;
+ this.setSize([this.size[0], HEADER_H + INPUT_WIDGETS_H + PADDING]);
+ if (app.canvas) app.canvas.setDirty(true, true);
+ };
+```
+
+**说明**:
+- 仅对 `NunchakuQwenImageLoraStackV1` 运行。
+- `serialize_widgets = true`:将控件值包含在发送给后端的 prompt 中。
+- "➕ Add Lora" 按钮:调用 `addLoraRowWithChooser`(显示 LoRA 菜单,然后添加行)。
+- `btn.serialize = false`:按钮本身不会被序列化;只有 LoRA 控件会被序列化。
+

+
+### 3.7 addLoraRowWithChooser、addLoraRow(第 216–247 行)
+
+```javascript
+ nodeType.prototype.addLoraRowWithChooser = async function (event) {

+ event: event,
+ callback: (value) => {
+ this.addLoraRow({ enabled: true, lora_name: value, lora_strength: 1.0 });
+ }
+ });
+ };
+
+ nodeType.prototype.addLoraRow = function (data = null) {
+ const name = `lora_${this.loraWidgets.length + 1}`;
+ const w = new NunchakuLoraWidget(name, this);
+ w.value = data || { enabled: true, lora_name: "None", lora_strength: 1.0 };
+
+ const btnIdx = this.widgets.findIndex(x => x.name === "➕ Add Lora");
+ this.widgets.splice(btnIdx, 0, w);
+ this.loraWidgets.push(w);
+
+ this.setSize([this.size[0], this.computeSize()[1]]);
+ this.setDirtyCanvas(true, true);
+ return w;
+ };
+```
+
+**说明**:
+- `addLoraRowWithChooser`:显示 LoRA 菜单,然后使用选中的 LoRA 添加一行。
+- `addLoraRow`:创建名为 `lora_1`、`lora_2`、… 的 `NunchakuLoraWidget`;将其插入到 Add Lora 按钮上方;更新大小和画布。
+
+---
+
+### 3.8 右键菜单:getSlotInPosition、getSlotMenuOptions、moveLora(第 249–315 行)
+
+```javascript
+ nodeType.prototype.getSlotInPosition = function (canvasX, canvasY) {
+ const slot = LGraphNode.prototype.getSlotInPosition.apply(this, arguments);
+ if (slot) return slot;
+
+ const widget = this.widgets.find(w => {
+ return w instanceof NunchakuLoraWidget &&
+ canvasY > (this.pos[1] + w.last_y) &&
+ canvasY < (this.pos[1] + w.last_y + WIDGET_HEIGHT);
+ });
+
+ if (widget) return { widget: widget, output: { type: "LORA_WIDGET" } };
+ return null;
+ };
+
+ nodeType.prototype.getSlotMenuOptions = function (slot) {
+ if (slot && slot.widget instanceof NunchakuLoraWidget) {
+ const widget = slot.widget;
+ return [
+ {
+ content: widget.value.enabled ? "⚫ Toggle Off" : "🟢 Toggle On",
+ callback: () => { widget.value.enabled = !widget.value.enabled; this.setDirtyCanvas(true); }
+ },
+ { content: "⬆️ Move Up", callback: () => this.moveLora(widget, -1) },
+ { content: "⬇️ Move Down", callback: () => this.moveLora(widget, 1) },
+ {
+ content: "🗑️ Remove",
+ callback: () => {
+ const idx = this.widgets.indexOf(widget);
+ this.widgets.splice(idx, 1);
+ this.loraWidgets = this.loraWidgets.filter(lw => lw !== widget);
+ this.setSize([this.size[0], this.computeSize()[1]]);
+ this.setDirtyCanvas(true);

+ }
+ ];

+
+ nodeType.prototype.moveLora = function (widget, dir) {
+ const idx = this.widgets.indexOf(widget);
+ const targetIdx = idx + dir;
+ if (this.widgets[targetIdx] instanceof NunchakuLoraWidget) {
+ this.widgets.splice(idx, 1);
+ this.widgets.splice(targetIdx, 0, widget);
+ this.setDirtyCanvas(true);
+ }
+ };
+```
+
+**说明**:
+- `getSlotInPosition`:如果点击不在真实插槽上,则检查是否位于 `NunchakuLoraWidget` 行上。如果是,则返回一个虚拟插槽以显示上下文菜单。
+- `getSlotMenuOptions`:对于该虚拟插槽,显示 Toggle On/Off、Move Up、Move Down、Remove。
+- `moveLora`:仅当目标为另一 LoRA 行时才重新排序控件(避免移动 model/cpu_offload 控件)。
+
+---
+
+### 3.9 onConfigure — 反序列化(第 317–338 行)
+
+```javascript
+ const onConfigure = nodeType.prototype.onConfigure;
+ nodeType.prototype.onConfigure = function (info) {
+ onConfigure?.apply(this, arguments);
+ if (info.widgets_values) {
+ this.widgets = this.widgets.filter(w => !(w instanceof NunchakuLoraWidget));
+ this.loraWidgets = [];
+
+ info.widgets_values.forEach((val, idx) => {
+ if (val && typeof val === 'object' && val.lora_name !== undefined) {
+ this.addLoraRow(val);
+ }
+ });
+
+ // Move Add Lora button to bottom (note: addLoraBtn must be set in onNodeCreated for this to run)
+ if (this.addLoraBtn) {
+ const btnIdx = this.widgets.indexOf(this.addLoraBtn);
+ this.widgets.splice(btnIdx, 1);
+ this.widgets.push(this.addLoraBtn);
+ }
+ }
+ };
+```
+
+**说明**:
+- 加载工作流时,`info.widgets_values` 包含序列化的控件值。
+- 移除现有的 LoRA 控件,然后通过 `addLoraRow(val)` 从 `widgets_values` 重新创建。
+- Add Lora 按钮被移回末尾(如果设置了 `this.addLoraBtn`;当前按钮创建为局部变量 `btn` 且未赋值给 `this.addLoraBtn`,因此此块不会运行——按钮顺序取决于 `addWidget` 的放置位置)。
+
+---
+
+## 4. 数据流:前端到后端
+
+1. 用户在 UI 中添加 LoRA 行;每个 `NunchakuLoraWidget` 都有 `value = {enabled, lora_name, lora_strength}`。
+2. 当用户对 prompt 排队时,ComfyUI 通过 `serialize_widgets = true` 序列化控件。每个控件的 `serializeValue()` 返回其 `value`。
+3. 序列化的 prompt 包含 `lora_1`、`lora_2`、… 作为控件输入。
+4. Python 的 `INPUT_TYPES` 使用 `FlexibleOptionalInputType()`,因此这些键被接受。
+5. `load_lora_stack` 在 `**kwargs` 中接收它们,按 `lora_` 前缀过滤、排序,并仅应用启用的 LoRA(具有有效名称且强度非零)。
+

+## 5. V4 到 V1 重命名总结
+
+| 项目 | V4(之前) | V1(之后) |
+|------|-----------|-----------|
+| Python 文件 | `qwenimage_v4.py` | `qwenimage_v1.py` |
+| JS 文件 | `z_qwen_lora_dynamic_v4.js` | `z_qwen_lora_dynamic_v1.js` |
+| 类名 | `NunchakuQwenImageLoraStackV4` | `NunchakuQwenImageLoraStackV1` |
+| 节点 ID | `NunchakuQwenImageLoraStackV4` | `NunchakuQwenImageLoraStackV1` |
+| 显示名称 | `Nunchaku Qwen Image LoRA Stack V4` | `Nunchaku Qwen Image LoRA Stack V1` |
+| 扩展名称 | `nunchaku.qwen_lora_dynamic_v4` | `nunchaku.qwen_lora_dynamic_v1` |
+| `__init__` 变量 | `QWEN_V4_NODES`、`QWEN_V4_NAMES` | `QWEN_V1_NODES`、`QWEN_V1_NAMES` |
+
+**破坏性变更**:使用 `NunchakuQwenImageLoraStackV4` 的工作流必须更新为使用 `Nunchaku Qwen Image LoRA Stack V1` 并重新配置。
