Custom data and dataloader object

my dataset is of this form, I want to create data and dataloader in pytorch on my final_train_data, final_test_data, final_train_label, final_test_label. I want to divide my data into 2 batches. Can you help me?
train_data = t.randn(12, 12)
test_data = t.randn(6,6)
train_label = t.randn(12, 12)
test_label = t.randn(6, 6)
train_data1 = t.randn(12, 12)
test_data1 = t.randn(6,6)
train_label1 = t.randn(12, 12)
test_label1 = t.randn(6, 6)

final_train_data = [train_data, train_data1]
final_test_data = [test_data, test_data1]
final_train_label = [train_label, train_label1]
final_test_label = [test_label, test_label1]
