# PaddleOCR
## Installation Guide
官方網站：[PaddleOCR](https://github.com/PaddlePaddle/PaddleOCR)、[CUDA Doucument](https://docs.nvidia.com/deeplearning/cudnn/support-matrix/index.html#cudnn-versions-714-721)
1.安裝 [CUDA 10.2](https://developer.nvidia.com/cuda-10.2-download-archive)
* 需要 [Visual Studio C++套件](https://pydatascience.gitbooks.io/pythondeeplearning/content/an-zhuang-nvidia-cuda-ji-cudnn.html)
2.下載(需要註冊)安裝 [CUDNN 7.6+(GPU)](https://pydatascience.gitbooks.io/pythondeeplearning/content/an-zhuang-cudnn.html)
* 覆蓋 CUDA 資料夾並<font color="#f00">將路徑加入環境變數 Path</font> (參考網頁中範例)，並重新開機
* cmd 輸入 nvcc --version 檢查
**(封裝後執行環境到此結束)**
3.根據 CUDA 版本，安裝(pip) [PaddlePaddle 2.0](https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/install/pip/windows-pip.html)
`pip install paddlepaddle-gpu==2.0.2 -i https://mirror.baidu.com/pypi/simple`
* 加入環境變數 Path (example) `.\p38\Lib\site-packages\paddle\include\paddle\fluid\platform\dynload`
* 查看 path : `import paddle` ， `paddle.__path__`
4.使用 [Github](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.1/doc/doc_ch/installation.md) 內的 requirements.txt 進行安裝 `pip3 install -r requirements.txt`
5.Python 輸入 `import paddle` ，再輸入 `paddle.utils.run_check()`，確認是否安裝成功
* 若出現 `geos_c.dll missing` ，輸入 `pip uninstall Shapely`
* 手動安裝 [Shapely](https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely)，example : `pip install Shapely‑1.7.1‑cp38‑cp38‑win_amd64.whl`

## Sample Code
```
from paddleocr import PaddleOCR
import cv2
import numpy as np
# 同样也是通过修改 lang 参数切换语种
ocr = PaddleOCR(lang="ch") # 首次执行会自动下载模型文件
img_path = r'D:\PaddleOCR\image\init.bmp'
img = cv2.imread(img_path)
result = ocr.ocr(img)
for i in range(len(result)):
pts = np.array([result[i][0]], np.int32)
pts = pts.reshape((-1,1,2))
cv2.polylines(img,[pts],True,(0,255,0))
cv2.putText(img, result[i][1][0], (int(result[i][0][3][0]), int(result[i][0][3][1])), cv2.FONT_HERSHEY_DUPLEX, 0.5, (0, 0, 255), 1, cv2.LINE_AA)
cv2.imshow("img",img)
cv2.waitKey(0)
