PyTorch NestedTensors优化方案 接下来,评估在PyTorch NestedTensors下的应用。这是一个目前处于原型阶段的特性,它允许我们直接处理不同长度的张量,这些张量被称为"jagged"或"ragged"张量。这种方法避免了显式填充的需求,但需要特别注意张量操作的兼容性。 以下代码展示了如何使用NestedTensors处理变长序列: def nested...
then converting it back to a jagged tensor. The forward pass is just fine, but the backwards pass breaks. It is probably because the offsets object changes throughout the forward pass, but I cannot see how to fix this.
🚀 The feature, motivation and pitch 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 ...

self.use_nested_tensor是一个实例变量,用于记录当前实例(可能是模型的一个组件)是否实际使用了嵌套张量。这个变量通常在模型或组件的初始化过程中根据配置和其他条件进行设置。 分析两者之间的关系,为何出现不一致: 不一致的原因可能在于enable_nested_tensor的配置没有在模型的初始化过程中被正确应用。例如,如果enable...

而 treevalue 最为强大的地方体现在treetensor中,只需要对部分 torch.Tensor 的方法进行特别支持后,剩下的全部方法均可在现有框架上实现,并保持和原有API一样的使用方式。 这一点,意味着对于基于 treevalue 的开发者而言,不再需要大规模逐个进行封装迁移,只需要针对个别较特殊的API进行特别实现,其他的可以直接批量...
