I have a file that has attributes with nested compound type, when
reading it with PyTables 2.4.0 I get this error:
C:\Python27\lib\site-packages\tables\attributeset.py:293:
DataTypeWarning: Unsupported type for attribute 'BmiRoot' in node '/'.
Offending HDF5 class: 6
value = self._g_getAttr(self._v_node, name)
C:\Python27\lib\site-packages\tables\attributeset.py:293:
DataTypeWarning: Unsupported type for attribute 'BmiChanExt' in node
'channel00001'. Offending HDF5 class: 6
value = self._g_getAttr(self._v_node, name)
Hard to say what exactly happens, just wanted to know if this is not
already fixed in newer versions I will be more than happy to work on
it, any pointers as to where to look is appreciated.
Here is the (partial) dump of the file (for brevity I deleted
non-related data parts but can provide the full file if needed):
