Question

我有一个pandas HDFStore对象（pandas使用PyTables实现HDF5，如果相关的话）和mydata DataFrame（store["mydata"] = mydata）并且有一些代码可以定期将数据附加到{{1} } DataFrame。当我尝试访问该HDFStore时，我收到此错误。

mydata

这是我打印时商店的样子。

//anaconda/lib/python2.7/site-packages/tables/group.py:1213: UserWarning: problems loading leaf ``/mydata/table``::

Problems reading the array data.

The leaf will become an ``UnImplemented`` node.
  % (self._g_join(childname), exc))

我不确定为什么会这样。

要处理数据，我从其他位置复制并粘贴了<class 'pandas.io.pytables.HDFStore'> File path: ../path/to/panda/store.h5 /mydata [invalid_HDFStore node: 'UnImplemented' object has no attribute 'description']文件（如果重要，则不调用.h5）。这可能是错误的来源，还是因为我用.close()附加数据？
