对单模型而言，如果你的模型有多组参数，而你想为它们设置不同优化器超参。此时，如果你对整个模型统一调用 prepare 方法，这些参数的组别信息会丢失，你会看到如下告警信息:FSDP Warning: When using FSDP, several parameter groups will be conflated into a single one due to nested module wrapping and paramet...

PyTorch Map: PyTorch map is a function that applies a specific operation to each element of a tensor or a nested sequence of tensors, resulting in a new tensor with the same shape as the input. It is implemented using the `torch.map_()`` function.PyTorch Mapping Op: PyTorch mapping ope...

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))。据说NumPy将Python相当于变成一种免费的更强大的MatLab系统。 NumPy(Numeric Python)提供了许多高级的数值编程工具,如:矩阵数据类型、矢量...

在关系抽取中词序信息和树结构信息是可以互补的。比如,在句子“This is …, one U.S. source said”中,词之间的依存信息不足以预测‘source’和‘U.S.’之间的‘ORG-AFF’关系。很多传统的基于特征工程的关系分类方法从序列和解析树中抽取特征。然而,之前基于RNN的模型仅关注于这些语言结构的一种。
