Tensorflow提供参差不齐的张量(https://www.tensorflow.org/guide/ragged_tensor)。但是,PyTorch不提供这种数据结构。有没有在PyTorch中构造类似内容的解决方法?
import numpy as np
x = np.array([[0], [0, 1]])
print(x) # [list([0]) list([0, 1])]
import tensorflow as tf
x = tf.ragged.constant([[0], [0, 1]])
print(x) # <tf.RaggedTensor [[0], [0, 1]]>
import torch
# x = torch.Tensor([[0], [0, 1]]) # ValueError
