[PaddlePaddle/PaddleOCR]训练ser任务报错

环境是ubuntu

Traceback (most recent call last): File "tools/train.py", line 227, in main(config, device, logger, vdl_writer) File "tools/train.py", line 135, in main model = build_model(config['Architecture']) File "/mnt/workspace/PaddleOCR/ppocr/modeling/architectures/init.py", line 30, in build_model arch = BaseModel(config) File "/mnt/workspace/PaddleOCR/ppocr/modeling/architectures/base_model.py", line 55, in init self.backbone = build_backbone(config["Backbone"], model_type) File "/mnt/workspace/PaddleOCR/ppocr/modeling/backbones/init.py", line 80, in build_backbone module_class = eval(module_name)(*config) File "/mnt/workspace/PaddleOCR/ppocr/modeling/backbones/vqa_layoutlm.py", line 156, in init num_classes=num_classes) File "/mnt/workspace/PaddleOCR/ppocr/modeling/backbones/vqa_layoutlm.py", line 66, in init base_model, num_classes=kwargs["num_classes"], dropout=None) File "/usr/local/lib/python3.7/dist-packages/paddlenlp/transformers/utils.py", line 249, in impl init_func(self, args, **kwargs) TypeError: init() got an unexpected keyword argument 'num_classes'

我把配置文件的num_classes注释了的话，又会报错：yaml.composer.ComposerError: found undefined alias 'num_classes' in "configs/kie/vi_layoutxlm/ser_vi_layoutxlm_xfund_zh.yml", line 40, column 16

I also meet the same problem. If I leave "checkpoints:" empty, this would be occur!

1. class_list.txt:

   

2. yml文件：

   

3. 有一种说法，叫做 num_classes = 2n-1。也就是说，class_list.txt里面有3行，所以num_classes = 2 * 3 - 1 = 5

谢谢解答，我用的是开源的XFUND数据集的标签好像就是2*4-1=7，好像不是标签数目的报错

I uninstalled paddlenlp==2.6.2 and install 2.5.2 and it work well, hope that this thing can helpful with you!

paddlenlp更新到2.6.0后出现的报错，ser和re出现了不同的问题，downgrade到2.5.2可以解决。

请问你的paddlepaddle-gpu版本是多少，是在aistudio平台上跑的吗

请问最后是怎么解决的，将paddlenpl降级到2.5.2吗
