Now comes the exciting part - generating data based on our schema. Before we dive in, let’s ensure we have everything set up correctly.

​
Environment Setup

Before we dive into the data generation rodeo, we need to make sure our environment variables are in place. You know things like api keys etc ? Yeah, those guys. We support envs in YAML. Make sure they’re all cozied up in your .env file. And don’t worry, our schema parser is pretty smart - it can sniff out these variables using the $VARIABLE_NAME syntax, like $OPENAI_API_KEY

​
Running the Data Generation

With our schema and environment variables in place, we’re ready to generate data. Here’s where the rubber meets the road. Open up your terminal, take a deep breath, and type: 
cyrus run --schema-path path/to/your/schema.yaml --env-path path/to/your/.env
You’ll be greeted by a cheeky ASCII art of the Cyyrus - our way of saying, “Buckle up, buttercup, you’re in for a wild ride!”. As Cyrus revs up, you’ll see a flurry of log messages. Don’t worry, that’s just some of Cyyrus initialization logs: 
2024-08-31 18:04:26,280 - cyrus.cli.main - INFO - CLI started. Buckle up, it's going to be a wild wild ride!
2024-08-31 18:04:26,287 - cyrus.models.spec - INFO - Reading spec from path/to/your/schema.yaml
2024-08-31 18:04:26,288 - cyrus.models.spec - INFO - Parsing the spec
2024-08-31 18:04:26,298 - cyrus.models.spec - INFO - Parsed and validated the spec
2024-08-31 18:04:26,299 - cyrus.cli.main - INFO - Spec loaded. Ready to roll!

​
Dry Run

We know you might be a bit nervous about generating a gazillion datapoints right off the bat. So, we’ll ask you to preview the execution without actually generating data: 
Do you want to perform a dry run? [Y/n]:
A dry run simulates the data generation process, showing you what would happen without actually executing the tasks. This is useful for verifying your schema and catching potential issues early. Think of this as a dress rehearsal.

​
Full Run

But let’s be honest, you didn’t come here to play pretend. So when Cyrus asks: 
Do you want to perform a full run? [Y/n]: y
You know what to do. Smash that y key and let’s get started. During the full run, Cyrus processes each column defined in your schema, handling dependencies, types, error cases, and one-to-many mappings. The system executes tasks in the order specified, ensuring data integrity and consistency. You’ll see progress bars and logs for each step: 
2024-08-26 16:01:14,096 - cyrus.composer.core - INFO - Preparing column: parsed_invoice
2024-08-26 16:01:14,097 - cyrus.composer.core - INFO - Executing task: TaskType.PARSING

Exporting the Dataset

But we’re not done yet! After generation, you’ll have the option to export your dataset: 
Ready to export the dataset? [y/N]: y
Enter the export directory [/Users/Code/cyrus]: export
Enter the export format (huggingface, json, csv, pickle, parquet) [huggingface]: json
Enter a name for your dataset (How about: Pierce_Macadamia ?) [Pierce_Macadamia]: invoice
Choose your flavor - JSON, CSV, pickle, parquet - Cyrus has got you covered.

But why stop there? Let’s share your newly created dataset. We’re in love with Huggingface lets make it official.
