KeyError: "unable to open object (Symbol table: Can't open object)"

[Siva Reddy Gangireddy]

Hi,

I got this error when I am trying to print the contents of the h5py file. 

2

Traceback (most recent call last):

  File "weight_save.py", line 25, in <module>

    print f['/dest2'].value.ndim

  File "/afs/inf.ed.ac.uk/user/s12/s1264845/software/tnets_venv/lib/python2.6/site-packages/h5py/_hl/group.py", line 130, in __getitem__

    oid = h5o.open(self.id, self._e(name), lapl=self._lapl)

  File "h5o.pyx", line 176, in h5py.h5o.open (h5py/h5o.c:2727)

KeyError: "unable to open object (Symbol table: Can't open object)"

Sample code:

import h5py

import numpy

def weight_save(path):

    f = h5py.File(path + 'dset.h5', 'w')

    f['/'+'dset1'] = numpy.zeros((6,4), dtype=numpy.int32)

    f['/'+'dset2'] = numpy.zeros((6,4), dtype=numpy.int32)

    f.close()

    return None

path = '/afs/inf.ed.ac.uk/user/s12/s1264845/scratch/s1264845/'

weight_save(path)

f = h5py.File(path + 'dset.h5', 'r')

print f['/dset1'].value.ndim

print f['/dest2'].value.ndim             #Error occurred at this line

Could any one help me to fix this error. Thanks in advance.

Hi Siva,

It means "/dest2" doesn't exist in the file.

Hi Andrew,

Thank you very much.

It was typing mistake and I didn't look into it properly.
