如何在 kaggle 上查看 .mdb 数据集？

Question

我以这种方式加载这个dataset：

Add data > Search for the dataset name (clova deep text ...) > Add

加载数据集并在侧边栏中可见后，我在每个子文件夹中找到了data.mdb 和lock.mdb。我需要检查内容、查看图像、查看标签……我应该如何打开/查看/修改这种奇怪格式的内容？

根据Luke 的建议，我尝试了apt install mbtools，安装开始，系统提示我输入y/n，但无法输入，因为单元格不允许。如果我尝试通过-y，我会得到unrecognized argument 的东西。然后我尝试了以下抱怨丢失包的方法。

pip install mbtools meza
from meza import io    
records = io.read('/kaggle/input/clova-deeptext/clova_deeptext/data_lmdb_release/training/ST/data.mdb')
print(next(records))

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv
You must install [mdbtools](http://sourceforge.net/projects/mdbtools/) in order to use this function

Answer 1

尝试使用以下 sn-p：

!sudo apt install mdbtools #  Library that allows access to MDB files programatically
!pip install meza # A Python toolkit for processing tabular data

from meza import io

records = io.read('database.mdb') # Use only file path, not file objects
print(next(records))
