The CypherA model serves as a magical translator, transforming everyday English sentences into Cypher queries that can be executed on graph databases like Neo4j. Imagine asking a question, “How many stations are between Koof Lane and Gag Street?” and the model outputs “3” in the blink of an eye! Buckle up as we guide you through this fascinating journey.

Getting Started with CypherA: Prerequisites

• To get your adventure rolling, ensure you have Python and Pipenv installed.
• From the root directory, run the following commands to install the necessary dependencies:

pipenv install
pipenv shell

Make sure that your command line Python invocations are performed after you’ve entered the Pipenv shell, giving you access to the required Python modules.

Getting Predictions: Running the Code

Now comes the fun part! To see the model in action, fire up the predict mode by using:

python -m e2c.predict

You’ll need a Neo4j database for this to work. Just a friendly warning, the code will erase everything in your database before uploading its own graph!

• The easiest way to create a new database with the needed extensions is to run Docker and utilize our script:

.start-neo4j-database.sh

If you want to specify a different database configuration, you can do so using:

--neo-user --neo-password --neo-url

The model will automatically download a trained model and its vocabulary if you don’t have them locally. Get excited as the prediction program kicks in, transforming your English questions into Cypher queries!

Code Explained: An Analogy

Let’s dive deeper into how the code works. Think of the code as a helpful librarian (the model) in a vast library (the graph database). Each question you ask (like “How clean is Fak Boulevard?”) is your way of seeking information from this librarian. The librarian then translates your question into a Dewey Decimal-like system (Cypher queries) so that she can fetch precisely the book (data) you want.

When you ask for the number of stations between two points, the librarian translates this into a request that finds the shortest path (using the query:
MATCH (var1) MATCH (var2) MATCH tmp1 = shortestPath((var1) -[*]-(var2)) …) and then counts the nodes (books) along the path. She brings back the precise number in seconds!

Training Your Own Model

If you’re feeling ambitious and want to train the model yourself, it will take about 1.5 hours on a recent NVIDIA GPU. Use the following command to build the text input data:

python -m e2c.build_data

Once that’s done, go ahead and run the training:

python -m e2c.train

Training can be slow without a GPU, but don’t worry. You can easily run this on Floyd Hub for better performance:

sudo pip install -U floyd-cli
floyd login
floyd train.sh

Troubleshooting Your Queries

While using the CypherA model, you may encounter some hurdles. Here are a few troubleshooting tips:

• Ensure that you are running the commands within the Pipenv shell.
• Verify your Neo4j database connection parameters are correct.
• If you receive errors related to missing trained models, make sure that the download completes without interruption.
• For further assistance, check the model’s documentation for common issues.
