rt-pose 0.0.3

Real-time (GPU) pose estimation pipeline with 🤗 Transformers

RT-Pose

Real-time (GPU) pose estimation pipeline with 🤗 Transformers

Installation

1. [Optional] It's recommended to run with uv for faster installation. First, install uv:

pip install uv

2. Install rt_pose (you can ignore uv in case you want to install with pure pip)

uv pip install rt-pose        # with minimal dependencies
uv pip install rt-pose[demo]  # with additional dependencies to run `scripts/` and `notebooks/`

Quick start

• Notebooks
• Python snippet
• Script to run on image
• Script to run on video

Notebooks

• Walkthrough for optimizations done - notebook
• Run inference on video - notebook

Python snippet

import torch
from rt_pose import PoseEstimationPipeline

# Load pose estimation pipeline
pipeline = PoseEstimationPipeline(
    object_detection_checkpoint="PekingU/rtdetr_r50vd_coco_o365",
    pose_estimation_checkpoint="usyd-community/vitpose-plus-small",
    device="cuda",
    dtype=torch.bfloat16,
    compile=False,  # or True to get more speedup
)

# Run pose estimation on image
output = pipeline(image)

# output.person_boxes_xyxy (`torch.Tensor`): 
#   of shape `(N, 4)` with `N` boxes of detected persons on the image in (x_min, y_min, x_max, y_max) format
# output.keypoints_xy (`torch.Tensor`):
#   of shape `(N, 17, 2)` with 17 keypoints per each person
# output.scores (`torch.Tensor`): 
#   of shape (N, 17) with corresponding scores (aka confidence) for each keypoint

# Visualize with supervision/matplotlib/opencv
# see ./scripts/run_on_image.py

Run pose estimation on image

• --input can be URL or path

python scripts/run_on_image.py \
    --input "https://res-3.cloudinary.com/dostuff-media/image/upload//w_1200,q_75,c_limit,f_auto/v1511369692/page-image-10656-892d1842-b089-4a7a-80f1-5be99b2b3454.png" \
    --output "results/image.png" \
    --device "cuda:0"

Run pose estimation on video

• --input can be URL or path
• --dtype it's recommended to run in bfloat16 precision to get the best precision/speed tradeoff
• --compile you can compile models in the pipeline to get even more speed up (x2), but compilation can be quite long, so it makes sense to activate for long videos only.

    --input "https://huggingface.co/datasets/qubvel-hf/assets/blob/main/rt_pose_break_dance_v1.mp4" \
    --output "results/rt_pose_break_dance_v1_annotated.mp4" \
    --device "cuda:0" \
    --dtype bfloat16
