二.首先拉取paddleocr源代码
下载地址https://gitee.com/paddlepaddle/PaddleOCR
三.下载模型 我要训练一个中文模型看到该预训练模型泛化性能最优于是下载这个模型 https://gitee.com/link?targethttps%3A%2F%2Fpaddleocr.bj.bcebos.com%2FPP-OCRv3%2Fchinese%2Fch_PP-OCRv3_rec_train.tar 其他模型地址https://gitee.com/paddlepaddle/PaddleOCR/blob/release/2.6/doc/doc_ch/models_list.md
四.训练前的准备
1.在源代码文件夹里创造一个自己放东西的文件 config文件夹用来装yml配置文件 pretrained_model用来装上一步下载的预训练模型 split_rec_label用来放数据集 output用来放训练出的模型 创建文件夹非强制只是这样更方便管理自己文件yml源文件地址就在 PaddleOCR-release-2.6/configs/rec/PP-OCRv3这个路径下
2.准备数据
2.1数据标注
参考博客https://blog.csdn.net/qq_49627063/article/details/119134847
2.2数据划分
在训练之前所有图片都在一个文件夹中所有label信息都在同一个txt文件中因此需要编写脚本将其按照8:1:1的比例进行分割。
import os

import shutil

3.改写yml配置文件

4.安装anaconda
参考博客https://blog.csdn.net/wyf2017/article/details/118676765
创建python虚拟环境
conda create -n ppocr切换虚拟环境
source activate ppocr五.开始训练
python tools/train.py -c wjp/ch_PP-OCRv3_rec_distillation.yml -o Global.pretrained_modelwjp/ch_PP-OCRv3_rec_train/best_accuracy
//-c参数放配置文件地址-o参数放预训练模型地址
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple
六.报错
1 libGL.so.1
ImportError: libGL.so.1: cannot open shared object file: No such file or directory解决办法
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python-headless2Polygon
ModuleNotFoundError: No module named Polygon解决办法
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple Polygon3(3) lanms
ModuleNotFoundError: No module named lanms源码下载地址https://github.com/AndranikSargsyan/lanms-nova/tree/master
参考我这个教程编译http://t.csdnimg.cn/BqOW6
将__init __.py文件替换
import numpy as npdef merge_quadrangle_n9(polys, thres0.3, precision10000):if len(polys) 0:return np.array([], dtypefloat32)p polys.copy()p[:, :8] * precisionret np.array(merge_quadrangle_n9(p, thres), dtypefloat32)ret[:, :8] / precisionreturn ret
找到linux种anaconda的包放在什么地方
pip show numpy就知道该环境下的包安装地址
将编译好库的整个lanms文件夹移动到该地址去即可调用
4报错UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xbc in position 2: invalid start byt
f open(txt01.txt,encodingutf-8)将 encoding’utf-8’ 改为GB2312、gbk、ISO-8859-1随便尝试一个均可以
5Out of memory error on GPU 0. Cannot allocate xxxxMB memory on GPU 0, xxxxGB memory has been allocated and available memory is only 0.000000B.
将训练的配置yml文件中的batch_size_per_card参数不断改小除以2直到不再报这个错即可。
