- Length: 150-300 English words

Loading Strategies

The node automatically selects the best loading strategy based on available GPU memory:

Strategy 1: Full GPU Loading

  • Condition: ≥7.5GB available GPU memory
  • Performance: ~26-30 tokens/second
  • Use Case: Standalone usage or minimal ComfyUI memory usage

Strategy 2: CPU Offload

  • Condition: <7.5GB available GPU memory
  • Performance: ~1-2 tokens/second (slower but reliable)
  • Use Case: When ComfyUI has loaded large models
  • Advantage: No memory conflicts, coexists with other models

Strategy 3: CPU Mode

  • Condition: No CUDA available
  • Use Case: CPU-only environments

Output

Output Type Description
text STRING Detailed professional photography prompt

Usage Examples

Example 1: Simple Chinese Input

Input: "一個女孩在咖啡廳"
Output: "A young woman sitting by the window in a cozy coffee shop, warm afternoon sunlight streaming through large glass windows creating soft shadows, wearing casual outfit, holding a cup of coffee, wooden table with laptop and notebook, blurred background with other customers, shallow depth of field, bokeh effect, warm color temperature, golden hour lighting..."

Example 2: English Input

Input: "a cat sitting on a windowsill"
Output: "A calico cat sitting on a sunlit windowsill, its long fur catching golden-hour light from the right, creating soft shadows across its face and body, wearing a quiet expression of peaceful solitude, surrounded by indoor plants and a wooden bookshelf in the background, shallow depth of field with bokeh-like blur..."

Memory Management

The node includes intelligent memory management:

  1. Pre-Load Check: Checks GPU memory before loading
  2. Automatic Cleanup: Clears CUDA cache if needed
  3. Dynamic Strategy: Chooses loading strategy based on available memory
  4. Device Distribution: Shows how model layers are distributed across GPU/CPU
  5. Clear Error Messages: Provides detailed error information and solutions

Performance Considerations

  • First Load: 7-130 seconds depending on hardware and memory
  • Subsequent Loads: Model stays in memory, near-instant
  • Full GPU: Fast inference (~26-30 tokens/second)
  • CPU Offload: Slower inference (~1-2 tokens/second) but prevents crashes
  • Memory Usage: ~7.5GB GPU memory for full GPU mode

Troubleshooting

Model not found

  • Ensure qwen_3_4b.safetensors is in models/text_encoders/
  • Check filename matches exactly (case-sensitive)

Out of memory

  • Node will automatically use CPU offload
  • If still failing, close other GPU applications
  • Consider restarting ComfyUI to free memory

Slow inference

  • Using CPU offload (expected behavior with low GPU memory)
  • For faster inference, free up GPU memory

Config download fails

  • Check internet connection
  • Manually download from Hugging Face if needed

Testing

A test script is provided: test_qwen_node.py

python test_qwen_node.py

This tests model loading, memory management, and inference capabilities.

功能特色

無條件進位:將AB相除結果無條件進位,以避免因尾數被捨去迴圈數目不足,導致多段影片或音檔分離時,末段音檔未被採樣

AudioSplitToList

Demo

功能特色

分割音檔為清單:將聲音檔分割為清單,長篇數字人時可分段採樣,目前已經更新音檔處理的邏輯,增加FADE功能

必需輸入:

  • videofps / 畫格 (Float): 每秒多少格
  • samplefps / 分段採樣格 (Int): 每段採樣多少格,範例,如果是25格,分段採樣格是75,則音檔將會分隔為每三秒一個單位
  • pad_last_segment / 補足音檔 (Boolean): 將音檔長度插入空白,對齊最後一格的分段採樣 (預設: False)

輸出:

  • cycle / 整數: 分割為多少段
  • audio_list / 音檔清單: 分割完成的音檔,可直接放入audio輸入,會依序處理
