I have 3.2+ million nodes I want to write to neo4j and almost twice as many relationships. I am using Cypher sessions and batches to create these nodes and relationships but it is taking *a lot* of time. What I think would be a good solution is to di...

I want to iterate two paths of nodes and make comparison on properties. Then update the nodes in the database accordingly. I connect to neo4j using the python driver and create a read transaction to get the paths. My function returns the nodes, but I...

I want to create parent nodes (intermediate nodes) for a linked list. In the nodes below, I want a parent node with head at (13) and tail at (17) and another one with head at (17) and tail at (21). However, when I find the nodes, it creates an extra...

Hello! I have introduced a graph model for the human genome and I am using Neo4j to achieve this objective. I am learning as I go and I am truly amazed that there is so much that can be done using Cypher. I am really happy to be a part of this commun...

I was getting the same error. The error didn't seem right because it was a csv file and there were plenty of newlines. It did have records for nodes and relationships but not long lines. I deleted my data and generated it again, then imported it. Wo...

rouven.bauer: last_node_path2 = path2.nodes[-1] Also, if the path return only one node, I get an index out of range error Traceback (most recent call last): File "F:\test\exampe.py", line 72, in main() File "F:\test\exampe.py", line 58, in m...

Thanks, this is very helpful. It to work well if I have one path. But if my MATCH path query returns more than one path or if I try to reterive a subset of a path using apoc.path.slice I get the following error: Traceback (most recent call last): Fi...

Thanks, I fixed it and now I am getting another error. To explain the directory structure: the neo4j.py and init.py files are in the folder F:\app-python\api I have made a new file here called myfile.py with the following code: import __init__ __ini...
