【问题描述】：
我是使用 pandas 和 python 的新手，我正在尝试将我拥有的 JSON 文件加载到 jupyter 笔记本中。我在将数据放入 Dataframe 时遇到了困难。
os.chdir('M:\JT\Voyages Data')
with open('M:\JT\Voyages Data\Data.json') as data:
data = json.load(data)
df = pd.DataFrame(data)
我无法打印出来，因为我不断收到错误提示
arrays must all be the same length
编辑***
很抱歉，这里没有尽快包含 JSON 文件中一些数据的副本，

您需要显示数据文件的内容（或至少一个示例），以便人们调试问题。为了安全/清晰，您可能还不想用
data（json）覆盖data（文件句柄）。
