title: How convert this type of data <hdf5 object reference> to something more readable in the python?
body: <p>I have quite big dataset. All information stored in the hdf5 format file. I found <a href="http://docs.h5py.org/en/latest/#" rel="noreferrer">h5py library</a> for python. All works properly except of the </p>
  
  <pre><code>[&lt;HDF5 object reference&gt;]
  </code></pre>
  
  <p>I have no idea how to convert it in something more readable. Can I do it at all ? Because documentation in this question slightly hard for me.
  Maybe there are some others solutions with different languages not only Python. I appreciate every help I will get.</p>
  
  <p>In the ideal it should be link to the file.</p>
  
  <p>It's the part of my code:</p>
  
  <pre><code>import numpy as np
  import h5py 
  import time
  
  f = h5py.File('myfile1.mat','r') 
  #print f.keys()
  test = f['db/path']
  st = test[3]
  print(  st )
  </code></pre>
  
  <p><code>st</code> output is <code>[&lt;HDF5 object reference&gt;]</code></p>
  
  <p><code>test</code> output is  <code>&lt;HDF5 dataset "path": shape (73583, 1), type "|O8"&gt;</code></p>
  
  <p>And I expect instead  <code>[&lt;HDF5 object reference&gt;]</code> something like that one: <code>/home/directory/file1.jpg</code>. If it is possible of course.</p>
