Exception: /home/XXX/dataset/pubtabnet/val/PMC3340316_005_00.png does not exist!

    上面给出部分示例， 目前官网上能下载到的数据集压缩包里面只有一个标签文件 截图 2022-12-05 17-15-26

一个标签文件里面有train、val、test的标签 因此在configs/table/SLANet.yml里面，train和val的label_lists我均只能给

    label_file_list: [/home/XXX/dataset/pubtabnet/PubTabNet_2.0.0.jsonl]

然后就会出现大量标签找不到图片的error，在标签文件里面"split": "train"，而在验证时它仍会从val/里面寻找

需要准备图片数据和标签文件才能训练哈

需要准备图片数据和标签文件才能训练哈

PubTabNet整个数据集我都下了下来，里面共有三个文件夹，一个标签文件，如上面官网图片所示

/home/XXX/dataset/pubtabnet/val/PMC3340316_005_00.png does not exist!

报错提示图片不存在，检查下配置是不是数据路径写错了

/home/XXX/dataset/pubtabnet/val/PMC3340316_005_00.png does not exist!

报错提示图片不存在，检查下配置是不是数据路径写错了

然而事实是这张图片在train文件夹里面，而且在标签jsonl文件里面它的'split'也是train,然后却在val文件夹下寻找，我也不明白为什么

由于这单个标签文件jsonl较大(2~3GB)，很难用一般编辑器打开，个人水平有限，也不太清楚去如何处理 但最后还是感谢您的解答

可以自己写Python脚本来处理哈，编辑器是不行的

emmm最后试了一下发现实现起来没那么困难

import jsonlines
import os

if __name__ == "__main__":
    label_root_path='/home/XXX/dataset/pubtabnet'  # Path of the label file folder
    label_path=os.path.join(label_root_path,'PubTabNet_2.0.0.jsonl')
    with jsonlines.open(label_path, "r") as f:
        with jsonlines.open(os.path.join(label_root_path,"PubTabNet_2.0.0_train.jsonl"), "w") as train_f:
            with jsonlines.open(os.path.join(label_root_path,"PubTabNet_2.0.0_val.jsonl"), "w") as val_f:
                for data in f:
                    if data['split']=='train':
                        train_f.write(data)

jsonl中单元格坐标和paddle的对不上，导致上面报错。怎么解决？

jjson坐标是4个数，paddlelabel是四个点，8个数
