Use your dataset
To use your dataset in a parameter, click "Use dataset" when providing the data to a parameter. This will allow you to select a dataset to use.
Datasets are sometimes way too large to fit in memory. In this case, the model can choose to load the data in small chunks called batches. This is automatically handled by decthings, and you do not need to do anything when specifying the dataset to use. The data will be provided to the model as the model requests it.
