# Embedl Mobilevit Small (Quantized for TensorRT) Deployable INT8-quantized version of [`apple/mobilevit-small`](https://huggingface.co/apple/mobilevit-small), optimized with [embedl-deploy](https://github.com/embedl/embedl-deploy) for low-latency NVIDIA TensorRT inference on edge GPUs. ## Upstream Model Open apple/mobilevit-small in hfviewer ## Highlights - **Mixed-precision INT8/FP16 quantization** with hardware-aware optimizations from [embedl-deploy](https://github.com/embedl/embedl-deploy). - **Drop-in replacement** for `apple/mobilevit-small` in TensorRT pipelines — same input shape (256×256), same output semantics. - **Validated accuracy** within 3.30 pp of the FP32 baseline on ImageNet (see Accuracy table below). - **Quantization-aware training (QAT)** further recovers accuracy lost in INT8 conversion by fine-tuning the model with simulated quantization in the forward pass. - **Matches the latency of `trtexec --best`** on supported NVIDIA hardware while preserving INT8 accuracy (see Performance table below). - Includes both **ONNX** (for TensorRT) and **PT2** (`torch.export`-loadable) artifacts plus runnable inference scripts. ## Quick Start ```bash pip install huggingface_hub onnxruntime-gpu pillow numpy python -c "from huggingface_hub import snapshot_download; snapshot_download('embedl/mobilevit-small-quantized', local_dir='.')" python infer_trt.py --image path/to/image.jpg # TensorRT # or python infer_pt2.py --image path/to/image.jpg # pure PyTorch via torch.export ``` ## Files | File | Purpose | |---|---| | `embedl_mobilevit_small_int8.onnx` | INT8-quantized ONNX with Q/DQ nodes — feed to TensorRT. | | `embedl_mobilevit_small_int8.pt2` | INT8-quantized `torch.export` ExportedProgram. | | `infer_trt.py` | Build a TRT engine from the ONNX and run sample inference. | | `infer_pt2.py` | Load the `.pt2` with `torch.export.load` and run sample inference. | ## Performance Latency measured with TensorRT + `trtexec`, GPU compute time only (`--noDataTransfers`), CUDA Graph + Spin Wait enabled, clocks locked (`nvpmodel -m 0 && jetson_clocks` on Jetson). MobileViT-Small benchmark on NVIDIA Jetson AGX Orin ### NVIDIA Jetson AGX Orin | Configuration | Mean Latency | Speedup vs FP16 | |---|---|---| | TensorRT FP16 | 1.28 ms | 1.00x | | TensorRT --best (unconstrained) | 1.09 ms | 1.17x | | **Embedl Deploy INT8** | **1.09 ms** | **1.17x** | ## Accuracy Evaluated on the ImageNet validation split. The quantized model retains nearly all of the FP32 accuracy with a small tolerance. | Model | Top-1 | Top-5 | |---|---|---| | `apple/mobilevit-small` FP32 (ours) | 78.14% | 94.08% | | **Embedl Mobilevit Small INT8** | **74.83%** | **92.28%** | ## Creating Your Own Optimized Models This artifact was produced with [embedl-deploy](https://github.com/embedl/embedl-deploy), Embedl's open-source PyTorch → TensorRT deployment library. You can apply the same workflow to your own models — see [the documentation](https://github.com/embedl/embedl-deploy#readme) for installation and usage. ## License | Component | License | |---|---| | Optimized model artifacts (this repo) | [Embedl Models Community Licence v1.0](https://github.com/embedl/embedl-models/blob/main/LICENSE) — no redistribution as a hosted service | | Upstream architecture and weights | [Mobilevit Small License](https://huggingface.co/apple/mobilevit-small) | ## Contact We offer engineering support for on-prem/edge deployments and partner co-marketing opportunities.
