Hi all,
I am a newbie to neo4j so please bare with me.
I installed neo4j for cpython and it is working fine. I can create graph
databases and everything. Since I need to insert a huge data set, I need to
use the batch inserter form neo4j in its Java form.
The problem that I am having is that, after creating my database using the
batch insert in Java, I am not able to open it using the python bindings.
I really need to use the python bindings because I will be doing a lot of
analysis using some python libraries. I have attempted to create the
database with different versions of neo4j (1.2, 1.3, and 1.4) and still get
the same result.
I am trying to open the database in python using: graphdb =
neo4j.GraphDatabase('fleedGraph')
The errors that I get are:
C:\Python26\lib\site-packages\jpype\_pykeywords.py:18: DeprecationWarning:
the sets module is deprecated

Traceback (most recent call last):

I hope someone can help me with this.
Best,
omar
