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...

as libtorch_python.so does not guarantee using APIs from from the stable Python limited API. In 2.7, we go further by specifying the-DPy_LIMITED_APIflag which will enforce that the extension is buildable with the limited API. As a result of this enforcement,custom extensions that setpy_limi...
FSDP Warning: When using FSDP, several parameter groups will be conflated into a single one due to nested module wrapping and parameter flattening. 告警信息表明,在使用 FSDP 对模型进行包装后,之前创建的参数组信息丢失了。因为 FSDP 会将嵌套式的模块参数摊平为一维数组 (一个数组可能包含多个子模块的参...
