适用于RKNN2的Segment Anything模型

Segment Anything Model for RKNN2 (English readme see below)

模型使用

• 安装RKNPU2 2.0.0b23版本运行库
• 在开发板上安装python-opencv, rknn-toolkit-lite2, onnxruntime等
• 从 https://huggingface.co/happyme531/segment-anything-rknn2 下载模型文件(sam_vit_b_01ec64.pth.encoder.patched.onnx.rknn,sam_vit_b_01ec64.pth.decoder.onnx)
• 执行run_sam_rknn.py即可

效果展示

输入:

提示：

{"type": "point", "data": [540, 512], "label": 1}

输出:

性能: RK3588，单NPU核心，耗时约22000ms
..性能瓶颈: Softmax太大，NPU无法执行

模型转换

• (使用RKNN-Toolkit2 2.0.0b23版本测试)
• 使用https://github.com/vietanhdev/samexporter 导出ONNX模型
• 编辑convert_encoder.py, 修改模型路径:

  ONNX_MODEL="sam_vit_b_01ec64.pth.encoder.onnx"
  

• 执行convert_encoder.py
• 现在会输出一个rknn文件, 但它的执行速度非常慢(~120s), 因为模型结构需要调整
• 执行patch_graph.py, 会生成调整后的onnx文件
• 再次编辑convert_encoder.py, 修改模型路径, 执行转换即可
• decoder模型运行很快，因此无需转换，直接用onnxruntime cpu运行即可

Model Usage

• Install RKNPU2 2.0.0b23 version runtime library
• Install python-opencv, rknn-toolkit-lite2, onnxruntime, etc. on the development board
• Download model files from https://huggingface.co/happyme531/segment-anything-rknn2 (sam_vit_b_01ec64.pth.encoder.patched.onnx.rknn, sam_vit_b_01ec64.pth.decoder.onnx)
• Execute run_sam_rknn.py

Demo

Input:

Prompt:

{"type": "point", "data": [540, 512], "label": 1}

Output:

Performance: RK3588, single NPU core, takes about 22000ms
..Performance bottleneck: Softmax is too large, NPU cannot execute

Model Conversion

• (Tested with RKNN-Toolkit2 2.0.0b23 version)
• Use https://github.com/vietanhdev/samexporter to export ONNX model
• Edit convert_encoder.py, modify the model path:

  ONNX_MODEL="sam_vit_b_01ec64.pth.encoder.onnx"
  

• Execute convert_encoder.py
• Now it will output an rknn file, but its execution speed is very slow (~120s) because the model structure needs adjustment
• Execute patch_graph.py, which will generate an adjusted onnx file
• Edit convert_encoder.py again, modify the model path, and execute the conversion
• The decoder model runs quickly, so there's no need for conversion. It can be run directly using onnxruntime CPU.
