pandas追加时的hdfstore错误

Question

我遇到了以下错误：

    exportStore.append(key, hdfStoreLocal, index = False, data_columns = True)
  File "/usr/local/lib/python2.7/dist-packages/pandas-0.14.1-py2.7-linux-x86_64.egg/pandas/io/pytables.py", line 911, in append
    **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/pandas-0.14.1-py2.7-linux-x86_64.egg/pandas/io/pytables.py", line 1270, in _write_to_group
    s.write(obj=value, append=append, complib=complib, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/pandas-0.14.1-py2.7-linux-x86_64.egg/pandas/io/pytables.py", line 3605, in write
    **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/pandas-0.14.1-py2.7-linux-x86_64.egg/pandas/io/pytables.py", line 3293, in create_axes
    raise e
ValueError: invalid itemsize in generic type tuple

有没有人知道为什么会出现这个问题？这是一个比较大的项目，所以我不太确定可以提供哪些代码，但这个错误发生在第一次添加的时候。任何帮助都非常感谢。
