How to use it with your own dataset?

- are `fsID `and `salience `necessary and if so, what do they mean?
- where to set the filename of the csv in the `metadata `subfolder?
- I get `ValueError: With n_samples=0, test_size=0.3 and train_size=None, the resulting train set will be empty. Adjust any of the aforementioned parameters.` with my training set. What is the likely cause? "Not found"?
