Creating Tables Issue

[icaoberg]

we had an issue and would like your feedback, if possible. at this we are using the omerocli to import and attach H5 tables to these images. at some point last night we starting getting this error

Code: Select all

/usr/lib/python2.5/site-packages/pyslid/features.pyc in link(conn,
iid, scale, fids, features, set, field, rid, pixels, channel, zslice,
timepoint, debug)
     703             #table for cell level features (roi == regions of
interest)
     704             table = conn.getSharedResources().newTable( 1,
'iid-' + str(iid) + '_feature-' + str(set) + '_roi.h5' )
--> 705         table.initialize(columns)
     706
     707         try:
AttributeError: 'NoneType' object has no attribute 'initialize'


since i know this error occurs when the table is nonetype i tried making a dummy table and got the same result. i restarted omero and the problem remained. then i restarted the node and now it works. we figure out there might be a memory leak. do you have any recommendations on how to handle this particular issue?

I'd guess that there was an exception creating the Table. We'd have to see the Tables-0.log to see what might have happened.

[icaoberg]

how are exceptions reported in the log file? it would be easier to grep for a line. we have more than ten log files at the moment.

ERROR would be a good start, Ivan, but really just the latest log file (var/log/Tables-0.log) would probably be the most useful. ~J.

Hi,

same problem here. Working through the example code in http://trac.openmicroscopy.org.uk/ome/w ... MEROtables fails on newTable() resulting in type(table) == NoneType.

@icaoberg: Have you solved your issue?

Here is the complete Table-0.log after OMERO restart:

If you try the following Christian can you then create a table?

Code: Select all

...
$ bin/omero admin ice 'server stop Tables-0'
...


What that does is just restart the OMERO.tables process.

Hi,

Thank you for your advice. But the reason for my issue was a broken PyTables setup. PyTables tried to use outdated HDF5 shared libs from a Matlab installation.

Best,
