PP-OCRv5 PyTorch Model Zoo

PyTorch weights (safetensors format) for the full PP-OCRv5 family, converted bit-exactly from the official PaddlePaddle .pdparams dynamic-graph weights — inference outputs are identical to the original PaddleOCR down to float32 precision.

Text Detection: 2 models (mobile / server)
Text Recognition (base): 2 models covering Simplified Chinese / Traditional Chinese / English / Japanese
Text Recognition (multilingual): 11 models covering 100+ languages (Korean, French, German, Russian, Arabic, Devanagari, Thai, Greek, Tamil, Telugu, etc.)

This repo contains weights + configs + dictionaries only, not inference code. For inference, use PaddleOCR2Pytorch, or follow the "Custom Python Inference" section below.

Also available: README_zh.md (中文版).

Quick Start

Download Weights

python

from huggingface_hub import snapshot_download, hf_hub_download

# Option 1: download the whole repo (weights + configs + dicts + README)
repo_dir = snapshot_download(repo_id="JoyCN/PaddleOCR-Pytorch")
print("downloaded to:", repo_dir)

# Option 2: fetch a single weight file
weight_path = hf_hub_download(
    repo_id="JoyCN/PaddleOCR-Pytorch",
    filename="ptocr_v5_korean_mobile_rec.safetensors",
)

Inference via PaddleOCR2Pytorch (Recommended)

bash

# 1. clone the inference code repo
git clone https://github.com/frotms/PaddleOCR2Pytorch
cd PaddleOCR2Pytorch
pip install torch safetensors pyyaml shapely pyclipper opencv-python pillow scikit-image

# 2. Assume you ran snapshot_download above into /path/to/hf_repo
python tools/infer/predict_rec.py \
  --image_dir doc/imgs_words/korean/1.jpg \
  --rec_algorithm SVTR_LCNet \
  --rec_model_path /path/to/hf_repo/ptocr_v5_korean_mobile_rec.safetensors \
  --rec_yaml_path  /path/to/hf_repo/configs/rec/PP-OCRv5/multi_language/korean_PP-OCRv5_mobile_rec.yml \
  --rec_image_shape "3,48,320" \
  --rec_char_dict_path /path/to/hf_repo/dicts/ppocrv5_korean_dict.txt \
  --use_gpu False

PaddleOCR2Pytorch base_ocr_v20.py auto-detects .safetensors vs .pth by extension (backward compatible).

Custom Python Inference

A minimal skeleton showing how to load the weights and run a forward pass. You still need the network definitions from the PaddleOCR2Pytorch pytorchocr/modeling/ package.

python

import sys, numpy as np, cv2, torch, yaml
from safetensors.torch import load_file

# Requires https://github.com/frotms/PaddleOCR2Pytorch on PYTHONPATH
sys.path.insert(0, "/path/to/PaddleOCR2Pytorch")
from pytorchocr.modeling.architectures.base_model import BaseModel
from pytorchocr.postprocess import build_post_process

HF_REPO = "/path/to/hf_repo"   # the path returned by snapshot_download
yml_path    = f"{HF_REPO}/configs/rec/PP-OCRv5/multi_language/korean_PP-OCRv5_mobile_rec.yml"
weight_path = f"{HF_REPO}/ptocr_v5_korean_mobile_rec.safetensors"

# 1. load config + dictionary
with open(yml_path, encoding="utf-8") as f:
    cfg = yaml.safe_load(f)
dict_path = cfg["Global"]["character_dict_path"]          # './dicts/ppocrv5_korean_dict.txt'
dict_abs  = f"{HF_REPO}/{dict_path.lstrip('./')}"
with open(dict_abs, encoding="utf-8") as f:
    chars = [l.strip("\n\r") for l in f]
n_char = len(chars) + 2                                   # +1 blank, +1 space (if use_space_char)

# 2. build network + load weights (safetensors = zero-code-exec, mmap-fast)
cfg["Architecture"]["Head"]["out_channels_list"] = {
    "CTCLabelDecode": n_char,
    "SARLabelDecode": n_char + 2,
    "NRTRLabelDecode": n_char + 3,
}
net = BaseModel(cfg["Architecture"], out_channels=n_char)
net.load_state_dict(load_file(weight_path, device="cpu"))
net.eval()

# 3. preprocess (resize to [3, 48, 320], normalize to [-1, 1])
img = cv2.imread("input_word.jpg")
h, w = img.shape[:2]
ratio = w / h
tw = min(int(48 * ratio), 320)
img = cv2.resize(img, (tw, 48))
canvas = np.zeros((48, 320, 3), dtype=np.uint8)
canvas[:, :tw] = img
x = canvas.astype(np.float32).transpose(2, 0, 1) / 255.0
x = (x - 0.5) / 0.5
x = torch.from_numpy(x).unsqueeze(0)

# 4. forward + CTC decode
with torch.no_grad():
    logits = net(x)
post_op = build_post_process({
    "name": "CTCLabelDecode",
    "character_dict_path": dict_abs,
    "use_space_char": True,
})
result = post_op(logits)
print("prediction:", result)          # e.g. [('바탕으로', 0.9998)]

Runtime Dependencies

torch        >= 1.13
safetensors  >= 0.4
numpy, pillow, opencv-python
pyyaml, shapely, pyclipper
scikit-image                # required by det post-processing

Conversion & Verification

Source weights: official PaddlePaddle .pdparams from
https://paddle-model-ecology.bj.bcebos.com/paddlex/official_pretrained_model/
Converter: PaddleOCR2Pytorch — scripts converter/ppocr_v5_det_converter.py / converter/ppocr_v5_rec_converter.py
Verification: end-to-end inference was run on macOS Apple Silicon (M-series) CPU; multilingual rec outputs are bit-exact with the original PaddleOCR .pdparams (float32 values match to 8 decimal places).

Sample inference results (CPU, < 0.7 s / image):

Sample	Prediction	Confidence
Chinese `word_1.jpg`	韩国小馆	0.99797755
Korean `korean/1.jpg`	바탕으로	0.99977183
French `french/1.jpg`	de l'amendement,	0.99656343
Arabic `arabic/ar_1.jpg`	الكيصياوي	0.68281130

Legacy Files (`legacy/`)

Older PP-OCR (v2 / v3 / v4) checkpoints previously at the repo root have been moved into legacy/ for clarity. They are still present and continue to work — just add the legacy/ prefix to your path.

If you were previously using any of these URLs at the root:

legacy/ch_ptocr_mobile_v2.0_cls_infer.pth
legacy/ch_ptocr_v4_det_infer.pth
legacy/ch_ptocr_v4_rec_infer.pth
legacy/en_ptocr_v3_det_infer.pth
legacy/en_ptocr_v4_rec_infer.pth

The 15 PP-OCRv5 safetensors files remain at the repo root — their URLs did not change.
