# Keypoint Inference Benchmark

## Benchmark on Server
We tested benchmarks in different runtime environments。 See the table below for details.

| Model | CPU + MKLDNN (thread=1) | CPU + MKLDNN (thread=4) | GPU | TensorRT (FP32) | TensorRT (FP16) |
| :------------------------ | :------: | :------: | :-----: | :---: | :---: |
| LiteHRNet-18-256x192 | 88.8 ms |  40.7 ms | 4.4 ms | 2.0 ms | 1.8 ms |
| LiteHRNet-18-384x288 | 188.0 ms | 79.3 ms | 4.8 ms | 3.6 ms | 3.2 ms |
| LiteHRNet-30-256x192 | 148.4 ms | 69.0 ms | 7.1 ms | 3.1 ms | 2.8 ms |
| LiteHRNet-30-384x288 | 309.8 ms | 133.5 ms | 8.2 ms | 6.0 ms | 5.3 ms |
| PP-TinyPose-128x96 | 25.2 ms | 14.1 ms | 2.7 ms | 0.9 ms | 0.8 ms |
| PP-TinyPose-256x192 | 82.4 ms | 36.1 ms | 3.0 ms | 1.5 ms | 1.1 ms |

**Notes:**
- These tests above are based Python deployment.
- The environment is NVIDIA T4 / PaddlePaddle(commit: 7df301f2fc0602745e40fa3a7c43ccedd41786ca) / CUDA10.1 / CUDNN7 / Python3.7 / TensorRT6.
- The test is based on deploy/python/det_keypoint_unite_infer.py with image demo/000000014439.jpg. And input batch size for keypoint model is set to 8.
- The time only includes inference time.
