ComfyUI WanVideoWrapper(wan2.2)生成视频时遇张量尺寸不匹配错误的求助

问题背景

我目前在使用Wan 2.2结合ComfyUI-WanVideoWrapper生成自定义动作视频，核心需求是：提取一段输入视频中的动作序列，让单张参考图里的角色复刻这些动作，生成新的视频内容。

遇到的错误

按照官方提供的Workflow运行时，始终弹出张量尺寸不匹配的错误，具体报错信息如下：

Sizes of tensors must match except in dimension 2. Expected size 887 but got size 880 for tensor number 1 in the list.

我已做的调整与预处理

节点替换：将原Workflow中的DownloadAndLoadDepthAnythingV2Model节点（配置如下）替换为了DWPose的DWPreprocessor节点：

原节点配置：

{
  "id": 73,
  "type": "DownloadAndLoadDepthAnythingV2Model",
  "pos": [-1430.5018, -396.4539],
  "size": [441, 82],
  "order": 24,
  "mode": 2,
  "outputs": [ { "name": "da_v2_model", "type": "DAMODEL", "links": [82] } ],
  "properties": { "cnr_id": "comfyui-depthanythingv2", "ver": "003d7b44bafd3a8a4c3693a9ca3ddcd72f4883ab" }
}

替换后的DWPose节点配置：

"156": {
  "inputs": {
    "detect_hand": "enable",
    "detect_body": "enable",
    "detect_face": "enable",
    "resolution": 512,
    "bbox_detector": "yolox_l.onnx",
    "pose_estimator": "dw-ll_ucoco_384_bs5.torchscript.pt",
    "scale_stick_for_xinsr_cn": "disable",
    "image": ["96", 0]
  },
  "class_type": "DWPreprocessor",
  "_meta": { "title": "DWPose Estimator" }
}
