读取Pandas HDFStore时出错（使用PyTables）

Question

我有一个pandas HDFStore对象（pandas使用PyTables实现HDF5，如果相关的话），我有一个mydata数据帧（store["mydata"] = mydata），并且有一些代码定期将数据附加到mydata数据帧中。当我试图访问HDFStore时，我得到了这个错误。在

//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))

这就是我打印时商店的样子。在

我不知道为什么会这样。在

为了处理数据，我从另一个位置复制并粘贴了.h5文件（如果重要的话，不调用.close()）。这是错误的来源还是因为我在数据后面加上了format=table？在
