pypy import error

[vasiliy-bout]

I am trying to use ontospy library from pypy and get the following error when it gets to importing SPARQLStore:

>>>> import ontospy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/pypy-2.5.0-osx64/site-packages/ontospy/__init__.py", line 9, in <module>
    from .core.graph import Graph, SparqlEndpoint
  File "/usr/local/pypy-2.5.0-osx64/site-packages/ontospy/core/graph.py", line 36, in <module>
    from rdflib.plugins.stores.sparqlstore import SPARQLStore
  File "/usr/local/pypy-2.5.0-osx64/site-packages/rdflib/plugins/stores/sparqlstore.py", line 31, in <module>
    from elementtree import ElementTree
ImportError: No module named elementtree

My pypy --version gives the following output:

Python 2.7.8 (10f1b29a2bd2, Feb 02 2015, 21:22:55)
[PyPy 2.5.0 with GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)]

Here (http://lxml.de/tutorial.html) I found the tutorial with nice example of how to import ElementTree in a portable manner:

try:
  from lxml import etree
  print("running with lxml.etree")
except ImportError:
  try:
    # Python 2.5
    import xml.etree.cElementTree as etree
    print("running with cElementTree on Python 2.5+")
  except ImportError:
    try:
      # Python 2.5
      import xml.etree.ElementTree as etree
      print("running with ElementTree on Python 2.5+")
    except ImportError:
      try:
        # normal cElementTree install
        import cElementTree as etree
        print("running with cElementTree")
      except ImportError:
        try:
          # normal ElementTree install
          import elementtree.ElementTree as etree
          print("running with ElementTree")
        except ImportError:
          print("Failed to import ElementTree from any known place")

I think imports should be rewritten to be more portable.

how did you install ontospy and/or rdflib? which rdflib version?

import rdflib
rdflib.__version__

Hi, my version of rdflib is:

>>>> import rdflib
>>>> rdflib.__version__
'4.2.1'

I have installed these ontospy and rdflib using pip command from the pypy package, like this:

/usr/local/pypy-2.5.0-osx64/bin/pip install -U ontospy rdflib
