Update! From offline discussion with @kurtamohler and @ngimel, for the 1.9 release we plan to: implement torch.linalg.vector_norm implement torch.linalg.matrix_norm ensure torch.norm and torch.linalg.norm can be performantly implemented ...

bar = torch::linalg::inv(foo); bar = torch::linalg::norm(foo, 2, {0, 1}, false, torch::nullopt); 所有支持的函数详见官方文档。 1.11 神经网络相关函数 神经网络是torch的核心模块,常见的一些激活函数,卷积层都可以以函数的形式作用在Tensor上,这里写几个简单的例子: bar = torch::softmax(foo...

范数计算:torch.norm(tensor, p=None, dim=None, keepdim=False, out=None) 所有这些数学运算都支持自动微分,并且能够灵活地在 CPU 或 GPU 上运行。此外,如果涉及到的数据分布在多个设备上,还可以进行跨设备的运算。3. 数据类型转换 在PyTorch 中,数据类型转换是通过 torch.Tensor 类的方法或直接使用 torch.*...
