In order to do this you need to first convert the dataframe into a pytorch tensor. You can do this by , X_train_tensor = torch.from_numpy (X_train.values) I assume that you also have a Y_train DataFrame , so make a tensor from it too. Y_train_tensor = torch.from_numpy (Y_train.values)groupBy(): Groups the DataFrame using the specified columns, so we can run aggregation on them. See GroupedData for all the available aggregate functions. In GroupedData you can find a set of methods for aggregations on a DataFrame, such as sum(), avg(),mean(). So you have to group your data before applying these functions.
