飞桨PaddleOCR环境搭建

###### 1. 确认环境是否支持 ######

![在这里插入图片描述][2021031111265045.png_pic_left]  
我用的实践环境：  
一台Windows7\_x64，和一台Windows10\_x64  
Python 3.8.5  
pip 21.0.1  
我是安装的CPU版，对CUDA没有特别要求。

###### 2. 在PyCharm中创建一个新的工程 ######

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZtMDUxNw_size_16_color_FFFFFF_t_70_pic_center]

其中pip升级了一次，注意升级时要先把原来虚拟环境中的pip包删除，否则更新不了。

###### 3. 安装PaddleOCR包 ######

在虚拟环境中用pip安装

pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZtMDUxNw_size_16_color_FFFFFF_t_70_pic_center 2]

###### 4. 验证安装 ######

import paddle
    
    
    if __name__ == '__main__':
        paddle.utils.run_check()

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZtMDUxNw_size_16_color_FFFFFF_t_70_pic_center 3]

###### 5. 下载PaddleOCR repo代码 ######

可以用git clone（推荐）

git clone https://github.com/PaddlePaddle/PaddleOCR

也可以通svn checkout

svn co https://github.com/PaddlePaddle/PaddleOCR/trunk

在PyCharm中将PaddleOCR文件夹设置成源码目录  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZtMDUxNw_size_16_color_FFFFFF_t_70_pic_center 4]

###### 6. 安装相关第三方库 ######

cd PaddleOCR
    pip install -r requirements.txt

安装前可能需要修改一下仓库地址：https://mirror.baidu.com/pypi/simple/  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZtMDUxNw_size_16_color_FFFFFF_t_70_pic_center 5]  
并且这一步骤依赖vc14编译工具，否则会报错：  
![在这里插入图片描述][20210311150118418.png_pic_center]

可以按照提示从官方链接下载：[https://visualstudio.microsoft.com/visual-cpp-build-tools/][https_visualstudio.microsoft.com_visual-cpp-build-tools]  
然后双击安装

相关第三方库安装完成后的效果如下图：

直接下载解压后，可能出现压缩包内的某些“文件夹”会显示成“文件”。  
我试验了在Linux下用wget下载tar包，然后用tar -xf解压，可以解决此问题。感觉大概率应该是出在解压上，在windows上也可以尝试用别的解压软件试试看。

其中：

> \# -c后面设置训练算法的yml配置文件  
> \# -o配置可选参数  
> \# Global.checkpoints 参数指向训练中保存的模型参数文件，不用添加文件后缀.pdmodel，.pdopt或.pdparams。  
> \# Global.save\_inference\_dir 参数设置转换的模型将保存的地址。

转换完成后  
在inference/det\_db下生成了以下文件（文本检测模型）：

在inferencerec\_crnn下生成了以下文件（文本识别模型）：

在inference/cls下生成了以下文件（文本方向分类模型）：

我留意到，不同环境下生成的.pdmodel模型文件大小会不同（.pdiparams和.info对应文件大小相同），我在另一台windows10上的文件大小为：

> inference/det\_db/inference.pdmodel - 1149KB  
> inference/rec\_crnn/inference.pdmodel - 848KB  
> inference/cls/inference.pdmodel - 835KB
