I am converting a jagged nested tensor to a padded tensor, then adding Rotary positional embeddings, then converting it back to a jagged tensor. The forward pass is just fine, but the backwards pass breaks. It i
Nested tensors are a great way to handle a batch of sequences with different lengths, which is often the case in NLP or ViTs for images of very different resolutions. Often, you add acls_tokento the input tensor as the first token, which currently (awaik) is not straightforward with ne...
self.codegened_graph_stack = [] # this is used for tracking which GraphLowering instance---parent graph # or (nested) subgraph---is currently codegened; the primary use case is # including the graph instance into a cache key to avoid cross-graph # caching during lowering of nested subgra...

如果list是一个嵌套list,那么生成的tensor将是多维的。 python # 指定数据类型 my_tensor_float = torch.tensor(my_list, dtype=torch.float32) # 输出结果以验证 print(my_tensor_float) # 输出: tensor([1., 2., 3., 4., 5.], dtype=torch.float32) # 多维tensor的例子 nested_list = [[1, 2...
Numpy:NumPy系统是Python的一种开源的数值计算扩展。这种工具可用来存储和处理大型矩阵,比Python自身的嵌套列表(nested list structure)结构要高 效的多(该结构也可以用来表示矩阵(matrix))。专为进行严格的数字处理而产生。 Q3:numpy和Torch的转换 Q3 torch中的数学运算 ...
