报错背景

在huggingface上传数据集后，Dataset Viewer无法显示，报错：
The dataset viewer is not available for this split.

Cannot extract the features (columns) for the split 'train' of the config 'default' of the dataset.
Error code:   FeaturesError

在这里插入图片描述
查看了别人展示的数据展示都好好的，就下载了一个看一下
发现别人的json文件都是一行一个字典
而我的是一个列表包含了很多字典
所以我就开始想办法转换成他们那样

import json# 读取 JSON 文件
with open('train.json', 'r', encoding='utf-8') as f:data = json.load(f)# # 将每个字典写入到新文件中，每行一个字典
with open('train_new.json', 'w', encoding='utf-8') as f:for item in data:json_string = json.dumps(item, ensure_ascii=False)f.write(json_string + '\n')print("处理完成")
