But here is a little trick you can put your numpy arrays directly. x1 = np.array ( [1,2,3]) d1 = DataLoader ( x1, batch_size=3) This also works, but if you print d1.dataset type: print (type (d1.dataset)) # <class 'numpy.ndarray'>. While we actually need Tensors for working with CUDA so it is better to use Tensors to feed the DataLoader.
