Exception Always Triggered When Using Data Generation Mode

[SAbdulah]

This exception is always raised when I choose to use the data generation option:

throw std::domain_error("You need to set the data path before starting.");

However, when generating synthetic data, specifying a data path is not required. The current behavior requires users to specify a data path even in data generation mode, which seems unnecessary.

I am using this command with the main branch
