The returning type was only

np.ndarray, but it is possible to change the return type totorch.Tensorif we setconvert_to_numpytoFalse. The origin version can lead to wordy and inefficient codes because people don't know thatencode()can return Tensor. For example, the code in Tutorial usesencode()as follow:which has to convert the tensor to np.ndarray and then convert it into Tensor.
This code can be changed into:
embeddings = model.encode([sentence_1, sentence_2, sentence_3], convert_to_numpy=False)which is more effective.
