PyTorch与MindSpore API映射表

由社区提供的PyTorch APIs和MindSpore APIs之间的映射，可能在参数、输入、输出、逻辑功能和特定场景等方面存在差异，可详见各API描述或已提供的差异对比。

也欢迎更多的MindSpore开发者参与完善映射内容。

API映射一致标准及例外场景

API映射一致标准：API功能一致，参数个数或顺序一致，参数数据类型一致，参数默认值一致，参数名一致。同时满足所有一致条件被认为是API映射一致。

以下例外场景也被认为是API映射一致，

例外场景1：相较于API映射一致标准，仅API参数的输入数据类型支持范围不一样，包含以下2种子场景：

（1）MindSpore的API支持传入int、float、bool等类型的参数，但不支持传入int8或float64等小位宽数据类型的参数。

（2）MindSpore的API不支持传入复数类型的参数。

例外场景2：相较于MindSpore的API，PyTorch的API多出的参数是通用差异参数。通用差异参数存在的原因是PyTorch有部分参数是为性能优化等非功能性而增加的参数，MindSpore的性能优化机制与PyTorch不同。

例外场景3：如果能保证MindSpore的API在使用默认配置（或用户不配置）的情况下，能够实现与PyTorch对应API完全一致的功能，则MindSpore的API多于PyTorch的API的参数，功能不被认为是差异。

例外场景4：MindSpore将API中与PyTorch重载机制相关参数的默认值设置为None，PyTorch对应API的相应参数无默认值。

下面是例外场景4的举例， 在PyTorch 2.1中，torch.argmax具有两种API重载形式，分别是torch.argmax(input)和torch.argmax(input, dim, keepdim=False)，其中torch.argmax(input)返回输入Tensor中的最大值元素的索引，torch.argmax(input, dim, keepdim=False)返回输入Tensor在指定轴上最大值的索引。

mindspore.mint.argmax只有一种API形式，即mindspore.mint.argmax(input, dim=None, keepdim=False)，但mindspore.mint.argmax(input)与torch.argmax(input)功能相同，mindspore.mint.argmax(input, dim, keepdim)与torch.argmax(input, dim, keepdim)功能相同。相较于torch.argmax，mindspore.mint.argmax参数dim的默认值被设置为None，仅是为了适配torch.argmax的两种API重载形式，因此例外场景4也被认为是API映射一致。

通用差异参数表

因为框架机制原因，MindSpore不提供PyTorch的以下参数：

参数名	功能	说明
out	表示输出的Tensor	把运算结果赋值给out参数，MindSpore目前无此机制
layout	表示内存分布策略	PyTorch支持torch.strided和torch.sparse_coo两种模式, MindSpore目前无此机制
device	表示Tensor存放位置	包含设备类型及可选设备号。MindSpore的支持方案如下： 1. 创建Tensor后，默认在CPU上，在执行算子的时候，会根据mindspore.set_device自动拷贝到对应的device_target。 2. 如果想在创建了Tensor之后手动拷贝，也可以调用mindspore.Tensor.move_to接口。
requires_grad	表示是否更新梯度	MindSpore中可以通过Parameter.requires_grad控制
pin_memory	表示是否使用锁页内存	MindSpore目前无此机制
memory_format	表示Tensor的内存格式	MindSpore目前无此机制
stable	表示是否稳定排序	一般用在排序算法的API中，MindSpore目前无此功能
sparse_grad	表示是否对梯度稀疏化	MindSpore目前无此机制
size_average	PyTorch废弃参数	MindSpore中可以使用reduction参数替代
reduce	PyTorch废弃参数	MindSpore中可以使用reduction参数替代
