eigenvector centrality #73

Closed jonhealy1 closed 4 years ago

jonhealy1 commented 4 years ago

The eigenvector took about half an hour to run. I had to edit the docker-compose file to get it to run. There are other algorithms in neo4j we can try out.

This is what the Docker window looked like in terminal:

I encountered this error running python3 examine_Data.py:

py2neo.database.ClientError: ProcedureNotFound: There is no procedure with the name 
`algo.eigenvector.stream` registered for this database instance. Please ensure you've
 spelled the procedure name correctly and that the procedure is properly deployed.

Are you doing: 'docker-compose up neo4j' from the assignment3 folder?

I believe so, because I got the first two queries running just fine, the problem is from the last one. Is there any additional module I need to install?

jonhealy1 commented 4 years ago

It installs it in the docker-compose file

environment:

jonhealy1 commented 4 years ago

I feel like you may still be using docker instead of docker-compose What is your docker command?

SiRumCz commented 4 years ago

It installs it in the docker-compose file

environment:

  • NEO4J_dbms_memory_heap_max__size=4G
  • NEO4JLABS_PLUGINS=["apoc", "graph-algorithms"]
  • NEO4J_dbms_security_proceduresunrestricted=algo.,apoc._

Oh yes, I think you forgot to update this part.

jonhealy1 commented 4 years ago

You shouldn't need to update - I already did. We are not using the docker command like before. Docker-compose is completely different

jonhealy1 commented 4 years ago

You do$ docker-compose up neo4j

Then it runs this file: version: '3.3'

services: neo4j: image: neo4j:latest container_name: neo4j ports:

I am using docker-compose. The command I use is docker-compose up neo4j. I just looked at your docker-compose.yml file, it is missing some of the environments you listed in previous comment.

jonhealy1 commented 4 years ago

Oh ok. Sorry. Weird I don't know why it didn't push?

jonhealy1 commented 4 years ago

I think it's fixed now.

SiRumCz commented 4 years ago

yep, it looks very solid.
