+## 文字角度分类
+
+### 数据准备
+
+请按如下步骤设置数据集：
+
+训练数据的默认存储路径是 `PaddleOCR/train_data/cls`,如果您的磁盘上已有数据集，只需创建软链接至数据集目录：
+
+```
+ln -sf <path/to/dataset> <path/to/paddle_ocr>/train_data/cls/dataset
+```
+
+请参考下文组织您的数据。
+- 训练集
+
+首先请将训练图片放入同一个文件夹（train_images），并用一个txt文件（cls_gt_train.txt）记录图片路径和标签。
+
+**注意：** 默认请将图片路径和图片标签用 `\t` 分割，如用其他方式分割将造成训练报错
+
+0和180分别表示图片的角度为0度和180度
+
+```
+" 图像文件名                 图像标注信息 "
+
+train_data/cls/word_001.jpg   0
+train_data/cls/word_002.jpg   180
+```
+
+最终训练集应有如下文件结构：
+```
+|-train_data
+    |-cls
+        |- cls_gt_train.txt
+        |- train
+            |- word_001.png
+            |- word_002.jpg
+            |- word_003.jpg
+            | ...
+```
+
+- 测试集
+
+同训练集类似，测试集也需要提供一个包含所有图片的文件夹（test）和一个cls_gt_test.txt，测试集的结构如下所示：
+
+```
+|-train_data
+    |-cls
+        |- 和一个cls_gt_test.txt
+        |- test
+            |- word_001.jpg
+            |- word_002.jpg
+            |- word_003.jpg
+            | ...
+```
+
+### 启动训练
+
+PaddleOCR提供了训练脚本、评估脚本和预测脚本。
+
+开始训练:
+
+*如果您安装的是cpu版本，请将配置文件中的 `use_gpu` 字段修改为false*
+
+```
+# 设置PYTHONPATH路径
+export PYTHONPATH=$PYTHONPATH:.
+# GPU训练 支持单卡，多卡训练，通过CUDA_VISIBLE_DEVICES指定卡号
+export CUDA_VISIBLE_DEVICES=0,1,2,3
+# 启动训练
+python3 tools/train.py -c configs/cls/cls_mv3.yml
+```
+
+- 数据增强
+
+PaddleOCR提供了多种数据增强方式，如果您希望在训练时加入扰动，请在配置文件中设置 `distort: true`。
+
+默认的扰动方式有：颜色空间转换(cvtColor)、模糊(blur)、抖动(jitter)、噪声(Gasuss noise)、随机切割(random crop)、透视(perspective)、颜色反转(reverse),随机数据增强(RandAugment)。
+
+训练过程中除随机数据增强外每种扰动方式以50%的概率被选择，具体代码实现请参考：
+[randaugment.py.py](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/ppocr/data/cls/randaugment.py)
+[img_tools.py](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/ppocr/data/rec/img_tools.py)
+
+*由于OpenCV的兼容性问题，扰动操作暂时只支持linux*
+
+### 训练
+
+PaddleOCR支持训练和评估交替进行, 可以在 `configs/cls/cls_mv3.yml` 中修改 `eval_batch_step` 设置评估频率，默认每500个iter评估一次。评估过程中默认将最佳acc模型，保存为 `output/cls_mv3/best_accuracy` 。
+
+如果验证集很大，测试将会比较耗时，建议减少评估次数，或训练完再进行评估。
+
+**注意，预测/评估时的配置文件请务必与训练一致。**
+
+### 评估
+
+评估数据集可以通过`configs/cls/cls_reader.yml`  修改EvalReader中的 `label_file_path` 设置。
+
+*注意* 评估时必须确保配置文件中 infer_img 字段为空
+```
+export CUDA_VISIBLE_DEVICES=0
+# GPU 评估， Global.checkpoints 为待测权重
+python3 tools/eval.py -c configs/cls/cls_mv3.yml -o Global.checkpoints={path/to/weights}/best_accuracy
+```
+
+### 预测
+
+* 训练引擎的预测
+
+使用 PaddleOCR 训练好的模型，可以通过以下脚本进行快速预测。
+
+默认预测图片存储在 `infer_img` 里，通过 `-o Global.checkpoints` 指定权重：
+
+```
+# 预测分类结果
+python3 tools/infer_cls.py -c configs/cls/cls_mv3.yml -o Global.checkpoints={path/to/weights}/best_accuracy Global.infer_img=doc/imgs_words/en/word_1.png
+```
+
+预测图片：
+
+![](../imgs_words/en/word_1.png)
+
+得到输入图像的预测结果：
+
+```
+infer_img: doc/imgs_words/en/word_1.png
+    scores: [[0.93161047 0.06838956]]
+    label: [0]

+## TEXT ANGLE CLASSIFICATION
+
+### DATA PREPARATION
+
+Please organize the dataset as follows:
+
+The default storage path for training data is `PaddleOCR/train_data/cls`, if you already have a dataset on your disk, just create a soft link to the dataset directory:
+
+```
+ln -sf <path/to/dataset> <path/to/paddle_ocr>/train_data/cls/dataset
+```
+
+please refer to the following to organize your data.
+
+- Training set
+
+First put the training images in the same folder (train_images), and use a txt file (cls_gt_train.txt) to store the image path and label.
+
+* Note: by default, the image path and image label are split with `\t`, if you use other methods to split, it will cause training error
+
+0 and 180 indicate that the angle of the image is 0 degrees and 180 degrees, respectively.
+
+```
+" Image file name           Image annotation "
+
+train_data/word_001.jpg   0
+train_data/word_002.jpg   180
+```
+
+The final training set should have the following file structure:
+
+```
+|-train_data
+    |-cls
+        |- cls_gt_train.txt
+        |- train
+            |- word_001.png
+            |- word_002.jpg
+            |- word_003.jpg
+            | ...
+```
+
+- Test set
+
+Similar to the training set, the test set also needs to be provided a folder
+containing all images (test) and a cls_gt_test.txt. The structure of the test set is as follows:
+
+```
+|-train_data
+    |-cls
+        |- cls_gt_test.txt
+        |- test
+            |- word_001.jpg
+            |- word_002.jpg
+            |- word_003.jpg
+            | ...
+```
+
+### TRAINING
+
+PaddleOCR provides training scripts, evaluation scripts, and prediction scripts.
+
+Start training:
+
+```
+# Set PYTHONPATH path
+export PYTHONPATH=$PYTHONPATH:.
+# GPU training Support single card and multi-card training, specify the card number through CUDA_VISIBLE_DEVICES
+export CUDA_VISIBLE_DEVICES=0,1,2,3
+# Training icdar15 English data
+python3 tools/train.py -c configs/cls/cls_mv3.yml
+```
+
+- Data Augmentation
+
+PaddleOCR provides a variety of data augmentation methods. If you want to add disturbance during training, please set `distort: true` in the configuration file.
+
+The default perturbation methods are: cvtColor, blur, jitter, Gasuss noise, random crop, perspective, color reverse, RandAugment.
+
+Except for RandAugment, each disturbance method is selected with a 50% probability during the training process. For specific code implementation, please refer to:
+[randaugment.py.py](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/ppocr/data/cls/randaugment.py)
+[img_tools.py](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/ppocr/data/rec/img_tools.py)
+
+
+- Training
+
+PaddleOCR supports alternating training and evaluation. You can modify `eval_batch_step` in `configs/cls/cls_mv3.yml` to set the evaluation frequency. By default, it is evaluated every 500 iter and the best acc model is saved under `output/cls_mv3/best_accuracy` during the evaluation process.
+
+If the evaluation set is large, the test will be time-consuming. It is recommended to reduce the number of evaluations, or evaluate after training.
+
+**Note that the configuration file for prediction/evaluation must be consistent with the training.**
+
+### EVALUATION
+
+The evaluation data set can be modified via `configs/cls/cls_reader.yml` setting of `label_file_path` in EvalReader.
+
+```
+export CUDA_VISIBLE_DEVICES=0
+# GPU evaluation, Global.checkpoints is the weight to be tested
+python3 tools/eval.py -c configs/cls/cls_mv3.yml -o Global.checkpoints={path/to/weights}/best_accuracy
+```
+
+### PREDICTION
+
+* Training engine prediction
+
+Using the model trained by paddleocr, you can quickly get prediction through the following script.
+
+The default prediction picture is stored in `infer_img`, and the weight is specified via `-o Global.checkpoints`:
+
+```
+# Predict English results
+python3 tools/infer_rec.py -c configs/cls/cls_mv3.yml -o Global.checkpoints={path/to/weights}/best_accuracy TestReader.infer_img=doc/imgs_words/en/word_1.jpg
+```
+
+Input image:
+
+![](../imgs_words/en/word_1.png)
+
+Get the prediction result of the input image:
+
+```
