Subject: [PATCH 1/7] Mark Host-Container TRT integration complete

Update TODO.md to mark Phase 2 as COMPLETE: replace the planned files list with a completed implementation checklist (host TRT service, SharedMemoryInference, and host-aware deploy script), revise the IPC protocol filenames/status format, add a Jetson deployment snippet, and bump the last-updated date. Also add .DS_Store files in the repository root and examples/ (macOS metadata).

+# Depth Anything 3 - Jetson Orin NX Benchmarks
+
+Performance benchmarks for Depth Anything 3 (DA3) models running on NVIDIA Jetson Orin NX 16GB with TensorRT 10.3 optimization.
+
+**Test Date:** February 2, 2026
+**Hardware:** Jetson Orin NX 16GB (JetPack 6.2)
+**TensorRT Version:** 10.3
+**Precision:** FP16
+
+---
+
+## Executive Summary
+
+| Configuration | FPS | Latency | Use Case |
+|--------------|-----|---------|----------|
+| DA3-Small @ 256x256 | **110 FPS** | 9.1ms | High-speed robotics |
+| DA3-Small @ 308x308 | **93 FPS** | 10.9ms | Real-time robotics (recommended) |
+| DA3-Small @ 400x400 | **64 FPS** | 15.8ms | Balanced quality/speed |
+| DA3-Small @ 518x518 | **40 FPS** | 25.0ms | Higher quality |
+| DA3-Base @ 518x518 | **19 FPS** | 51.4ms | Quality-focused |
+| DA3-Large @ 518x518 | **7.5 FPS** | 132ms | Offline processing |
+
+**Recommendation:** For real-time robotics applications, use DA3-Small at 308x308 or 400x400 resolution for optimal speed/quality balance.
+
+---
+
+## Resolution Benchmarks (DA3-Small)
+
+Testing DA3-Small model at different input resolutions to find the optimal speed/quality tradeoff.
+
+| Resolution | Throughput (FPS) | Latency (mean) | Latency (p99) | Engine Size |
+|------------|------------------|----------------|---------------|-------------|
+| 518x518 | 40.09 | 25.0ms | 25.6ms | 64MB |
+| 400x400 | 63.58 | 15.8ms | 16.4ms | 60MB |
+| 308x308 | 92.58 | 10.9ms | 11.1ms | 60MB |
+| 256x256 | 110.20 | 9.1ms | 9.3ms | 56MB |
+
+### Resolution Scaling Analysis
+
+- **2x speedup:** Reducing from 518 to 400 yields 1.6x faster inference
+- **2.3x speedup:** 308x308 provides 2.3x improvement over native resolution
+- **2.7x speedup:** 256x256 achieves maximum throughput at 110 FPS
+
+### Quality Considerations
+
+Lower resolutions reduce depth map detail but maintain relative depth accuracy. For navigation and obstacle avoidance, 308x308 provides sufficient spatial resolution while enabling real-time performance.
+
+---
+
+## Model Size Benchmarks (518x518)
+
+Comparing DA3 model variants at native 518x518 resolution.
+
+| Model | Parameters | Throughput (FPS) | Latency (mean) | Latency (p99) | Engine Size |
+|-------|------------|------------------|----------------|---------------|-------------|
+| DA3-Small | ~24M | 40.05 | 25.0ms | 25.6ms | 64MB |
+| DA3-Base | ~97M | 19.24 | 51.4ms | 52.8ms | 211MB |
+| DA3-Large | ~335M | 7.51 | 132.2ms | 134.2ms | 674MB |
+
+### Model Scaling Analysis
+
+- **Small to Base:** 4x more parameters, 2x slower (19 vs 40 FPS)
+- **Base to Large:** 3.5x more parameters, 2.6x slower (7.5 vs 19 FPS)
+- **Small to Large:** 14x more parameters, 5.3x slower (7.5 vs 40 FPS)
+
+### Quality vs Speed Tradeoff
+
+| Model | Relative Quality | Relative Speed | Best For |
+|-------|-----------------|----------------|----------|
+| Small | Good | Fastest | Real-time robotics, embedded |
+| Base | Better | Moderate | Quality-sensitive applications |
+| Large | Best | Slowest | Offline processing, benchmarking |
+
+---
+
+## Memory Usage
+
+### GPU Memory (Estimated)
+
+| Model | Resolution | GPU Memory |
+|-------|------------|------------|
+| DA3-Small | 518x518 | ~1.2GB |
+| DA3-Small | 308x308 | ~0.8GB |
+| DA3-Base | 518x518 | ~2.5GB |
+| DA3-Large | 518x518 | ~6GB |
+
+### Disk Space (TRT Engines)
+
+| Configuration | Engine Size |
+|---------------|-------------|
+| DA3-Small (all resolutions) | ~240MB total |
+| DA3-Base (518x518) | 211MB |
+| DA3-Large (518x518) | 674MB |
+
+---
+
+## Deployment Recommendations
+
+### Real-Time Robotics (30+ FPS required)
+
+**Recommended:** DA3-Small @ 308x308 or 400x400
+- 308x308: 93 FPS with 11ms latency
+- 400x400: 64 FPS with 16ms latency
+- Both leave headroom for other processing
+
+### Quality-Focused Applications (15+ FPS acceptable)
+
+**Recommended:** DA3-Small @ 518x518 or DA3-Base @ 518x518
+- Small: 40 FPS, good quality
+- Base: 19 FPS, better quality for detailed scenes
+
+### Offline/Batch Processing
+
+**Recommended:** DA3-Large @ 518x518
+- 7.5 FPS suitable for non-real-time applications
+- Best depth quality for dataset generation
+
+---

Subject: [PATCH 7/7] Update Jetson TensorRT docs, benchmarks & scripts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Refresh Jetson/TensorRT documentation and deployment scripts to reflect new validation results and tooling changes. Key changes:

- README: update TensorRT performance claims (≈40 FPS @ 518x518, 93 FPS @ 308x308), speeds (7.7x / up to 17.8x), latency and benchmark references.
- docs/BASELINES.md: major rewrite with validated TensorRT FP16 tables, model/size throughput, thermal stability results and recommended configurations; update JetPack/CUDA versions and PyTorch baseline.
- docs/JETSON_DEPLOYMENT_GUIDE.md: adjust JetPack/CUDA versions, engine size (58 → 64 MB), performance numbers, host-container diagram formatting, shared-memory protocol (request/status), add model/benchmark/thermal script references, update validation date.
- Remove obsolete planning docs: docs/TENSORRT_DA3_PLAN.md and docs/TENSORRT_OPTIMIZATION_PLAN.md (deleted).
- scripts/demo.sh & scripts/deploy_jetson.sh: add auto-install and dependency checks (huggingface_hub, onnx, numpy, pycuda), improved ONNX download/embedding flow, better fallbacks to PyTorch when TRT unavailable, update displayed backend performance text and expected FPS.

These changes align docs and scripts with recently validated Jetson results, improve robustness of automated deployment (dependency handling and clearer fallbacks), and remove outdated planning artifacts.

-# Depth Anything V3 on Jetson Orin NX: TensorRT 8.6 won't work
-
-**The definitive answer: DA3 + TensorRT 8.6 is not achievable without TensorRT upgrade.** The ika-rwth-aachen repository—the only working DA3+TRT implementation—requires TensorRT 10.9, not 8.6. Your "caskConvolutionV2Forward" error stems from TRT 8.6's fundamental inability to process DINOv2's Einsum-based attention patterns. The solution is upgrading to **JetPack 6.2** (TensorRT 10.3), which fully supports Jetson Orin NX and includes a 70% AI TOPS boost via "Super Mode."
-
----
-
-## Why TensorRT 8.6 cannot build DA3 engines
-
-The DINOv2 backbone at DA3's core uses `F.scaled_dot_product_attention()` which exports to ONNX as complex Einsum operations. TensorRT 8.6 has three critical limitations:
-
-- **Einsum restrictions**: TRT 8.6 does not support more than 2 inputs, ellipsis notation, or diagonal operations in Einsum layers. DINOv2's attention patterns like `"nlhd,nhdv,nlh->nlhv"` fail completely.
-- **Missing ViT optimizations**: TRT 8.6 lacks Multi-Head Attention (MHA) fusion for Vision Transformers—attention operations remain as unoptimized separate MatMul/Softmax chains.
-- **Format incompatibility**: The error `"caskConvolutionV2Forward could not find any supported formats"` indicates TRT 8.6 cannot find compatible CUDA kernels for DINOv2's specific tensor format/precision combinations.
-
-NVIDIA's TensorRT GitHub Issue #4537 confirms these DINOv2 compilation failures persist even into early TRT 10.x versions, with full fixes arriving in **TensorRT 10.8+**.
-
----
-
-## How ika-rwth-aachen solves this (they use TRT 10.9)
-
-The ika-rwth-aachen/ros2-depth-anything-v3-trt repository achieves DA3+TRT compatibility through one key requirement: **TensorRT 10.9**. They don't use custom plugins, graph surgery, or workarounds—they simply rely on TRT 10.x's improved transformer support.
-
-Their tested configurations use Docker images `nvcr.io/nvidia/tensorrt:25.08-py3` and `nvcr.io/nvidia/tensorrt:25.03-py3`, both containing TensorRT 10.9 with CUDA 12.8+. The only preprocessing step is modifying DA3's source before ONNX export:
-
-```python
-# File: src/depth_anything_3/api.py
-# Change bfloat16 to float16 (ONNX doesn't fully support bfloat16)
-autocast_dtype = torch.float16  # NOT torch.bfloat16
-```
-
-Export uses fixed input shape `[1, 3, 280, 504]` and produces two outputs: metric depth and sky classification. Pre-built ONNX models are available at **huggingface.co/TillBeemelmanns/Depth-Anything-V3-ONNX**.

-
-## The upgrade path: JetPack 6.2 with TensorRT 10.3
-
-JetPack 6.2 is the production release for Jetson Orin NX with TensorRT 10.3—a massive upgrade from 8.6. This version includes critical ViT/transformer fixes and enables "Super Mode" which boosts your Orin NX 16GB to **up to 70% more AI TOPS**.
-
-| Component | JetPack 6.0 (Current) | JetPack 6.2 (Target) |
-|-----------|----------------------|---------------------|
-| TensorRT | **8.6** | **10.3** |
-| CUDA | 12.2 | 12.6 |
-| cuDNN | 8.9 | 9.3 |
-| ViT Support | Limited | Enhanced MHA fusion |
-
-**Upgrade procedure:**
-```bash
-# On Jetson Orin NX, upgrade from JetPack 6.0/6.1 to 6.2
-sudo apt-add-repository universe
-sudo apt-add-repository multiverse
-sudo apt-get update
-sudo apt-get install nvidia-jetpack
-sudo reboot
-```
-
-Note: Firmware update may be required. Verify post-upgrade with `dpkg -l | grep nvidia`. JetPack 7 is **not available** for Orin NX—it's exclusive to the new Jetson Thor platform.
-
----
-
-## Alternative approaches if upgrade is impossible
-
-### Option 1: ONNX Runtime hybrid execution (partial acceleration)
-
-ONNX Runtime with TensorRT Execution Provider can accelerate TRT-compatible ops while falling back to CUDA EP for problematic layers:
-
-```python
-import onnxruntime as ort
-
-sess = ort.InferenceSession('da3.onnx', providers=[
-    ('TensorrtExecutionProvider', {
-        'trt_op_types_to_exclude': 'Einsum,LayerNormalization',
-        'trt_fp16_enable': True,
-        'trt_engine_cache_enable': True
-    }),
-    'CUDAExecutionProvider'
-])
-```
-
-This yields **20-40% slower performance** than full TRT but remains faster than pure CUDA inference.
-
-### Option 2: Use Depth Anything V2 instead
-
-The spacewalk01/depth-anything-tensorrt repository provides working TRT 8.6 implementations for **V1 and V2 only**. V2 uses a similar DINOv2 backbone but with different intermediate feature extraction that happens to work with older TRT versions. Quality is comparable to V3 for many use cases.
-
-```bash
-# spacewalk01 export for V2
-python export_v2.py --encoder vitb --input-size 518
-```
-
-Known issue: INT64 weights require casting to INT32 on some Jetson configurations.
-
-### Option 3: Modify DINOv2 attention implementation (complex)
-
-Replace `scaled_dot_product_attention` with explicit operations before ONNX export:
-
-```python
-def explicit_attention(q, k, v, scale=None):
-    scale = scale or (1.0 / math.sqrt(q.size(-1)))
-    attn = (q @ k.transpose(-2, -1)) * scale
-    attn = F.softmax(attn, dim=-1)
-    return attn @ v
-```
-
-This requires forking DA3, modifying the DINOv2 backbone attention modules, and re-exporting to ONNX. Significant development effort with uncertain results on TRT 8.6.
-

-
-## Pre-built resources and working implementations
-
-| Resource | Description | URL |
-|----------|-------------|-----|
-| DA3 ONNX Models | Pre-exported ONNX (280×504 input) | huggingface.co/TillBeemelmanns/Depth-Anything-V3-ONNX |
-| ROS2 DA3 TRT Node | Working TRT 10.9 implementation | github.com/ika-rwth-aachen/ros2-depth-anything-v3-trt |
-| Jetson Orin Depth | V1/V2 for Jetson (small model only) | github.com/IRCVLab/Depth-Anything-for-Jetson-Orin |
-| Seeed Studio Guide | DA3 deployment on Jetson AGX Orin | wiki.seeedstudio.com/deploy_depth_anything_v3_jetson_agx_orin |
-| DA2 TensorRT | V1/V2 with TRT 8.6 support | github.com/spacewalk01/depth-anything-tensorrt |
-
-The IRCVLab repository works on Jetson Orin but recommends the **small (vits14) model only** due to memory constraints—larger models may exceed 16GB on Orin NX.
-
----
-
-## Conclusion
-
-**Upgrade to JetPack 6.2 is the definitive solution.** TensorRT 10.3 includes the transformer/ViT improvements necessary for DA3's DINOv2 backbone. No custom plugins, graph surgery, or architectural modifications exist that make DA3 work reliably on TRT 8.6—the Einsum limitations are fundamental.
-
-If upgrading is impossible, use ONNX Runtime's hybrid execution for partial TRT acceleration, or switch to Depth Anything V2 which has proven TRT 8.6 compatibility. The performance difference between V2 and V3 is marginal for most depth estimation tasks, making V2 a practical alternative when TRT version constraints cannot be changed.

-# TensorRT Optimization Plan for Jetson Deployment
-
-## Executive Summary
-
-The TensorRT optimization plan is **approved** with critical updates from the recent audit.
-
-**Audit Findings (Jan 30 2026):**
-1. **Resolution Mismatch**: 1024x1024 resolution (used for Large models) is NOT divisible by 14 (ViT patch size), which serves as a hard constraint.
-2. **Opset Compatibility**: Custom `ika-rwth-aachen` models (Opset 20) fail on TensorRT 8.6 due to missing Gelu plugin. Our plan uses `onnx-community` models which must be verified for compatibility.
-
-**Verdict: PROCEED with Plan + Resolution Fixes**
-
----
-
-## 1. Audit Analysis & Fixes
-
-### A. Resolution Constraint (Critical)
-**Finding**: ViT models require input dimensions divisible by 14.
-- `1024 / 14 = 73.14` (INVALID)
-- `1022 / 14 = 73.0` (VALID)
-- `1036 / 14 = 74.0` (VALID)
-
-**Fix**: Update `model_catalog.yaml` and `OPTIMIZATION_GUIDE.md` to use **1022** instead of 1024.
-
-### B. TensorRT Compatibility
-**Finding**: Logs show Opset 20 `Gelu` operator failure on TensorRT 8.6.
-**Mitigation**: 
-- Phase 3 uses `onnx-community` models. We must verify if they use Opset < 20 or if TRT 8.6 supports them.
-- **Fallback**: If FP16 build fails, fallback to ONNX Runtime with TensorRT execution provider (Phase 4 extension).
-
----
-
-## 2. Implementation Plan
-
-### Phase 1: Fix Dependencies in Dockerfile
-
-**File:** `Dockerfile`
-
-**Changes:**
-1. Add `python3-dev` to system dependencies.
-2. Add `pycuda`, `huggingface_hub`, `onnxruntime-gpu` (fallback).
-
-```dockerfile
-RUN if [ "$BUILD_TYPE" = "jetson-base" ]; then \
-        pip3 install --no-cache-dir pycuda huggingface_hub onnxruntime-gpu; \
-    fi
-```
-
-### Phase 2: Add TensorRT Build Arguments
-
-**File:** `Dockerfile`
-
-Add `BUILD_TENSORRT`, `TENSORRT_MODEL`, `TENSORRT_PRECISION`.
-
-### Phase 3: Implement Optional Engine Building
-
-**File:** `Dockerfile`
-
-Use `--auto` flag. **CRITICAL**: Update `scripts/build_tensorrt_engine.py` to target 1022 resolution for 'large' models instead of 1024.
-
-### Phase 4: Enhance Entrypoint Script
-
-**File:** `docker/ros_entrypoint.sh`
-
-Add runtime auto-build logic with fallback warning.
-
-### Phase 5: Fix docker-compose.yml
-
-Add `NVIDIA_DRIVER_CAPABILITIES` and volume mounts.
-
-### Phase 6: Update Configurations (Audit Fix)
-
-**File:** `config/model_catalog.yaml`
-
-Update all `1024` references to `1022`.
-
-```yaml
-AGX_ORIN_64GB:
-  height: 1022  # Changed from 1024 (must be divisible by 14)
-  width: 1022
-```
-
----
-
-## 3. Build Strategy Options
-
-### Option A: Build-Time (Baked into Image)
-- **Pros:** Fastest startup
-- **Cons:** Platform-specific
-
-### Option B: Runtime Auto-Build (Recommended)
-- **Pros:** Flexible, one-time delay
-- **Cons:** Startup delay on first run
-
----
-
-## 4. Verification Plan
-
-1. **Resolution Check**: Verify 1022x1022 works with `trtexec`.
-2. **Opset Check**: Verify `onnx-community` model Opset version matches TRT 8.6 support.
-3. **End-to-End**: Run `ros2 launch ...` with `log_inference_time:=true`.
-
----
-
-## 5. Risk Config
-
-| Risk | Mitigation |
-|------|------------|
-| Opset 20 not supported | Use older Opset export or ONNX Runtime fallback |
-| Resolution mismatch | Enforce mod-14 resolutions (1022, 518, 308) |
-| System Memory OOM | 1022x1022 requires ~4.5GB VRAM (Safe for AGX) |
-
----
-
-## Immediate Next Steps (Audit Response)
-
-1. **Update `model_catalog.yaml`**: Change 1024 -> 1022.
-2. **Update Docs**: Reflect 1022 as Ultra resolution.
-3. **Proceed with Docker fixes**: Implement dependencies and build args.
