models import resnet18 def init_model(): return resnet18().to(torch.float32).cuda() 首先比较下推理,这里用到了 torch.compile 的一个额外的 mode 参数,后面将会讨论。 def evaluate(mod, inp): return mod(inp) model = init_model() # Reset since we are using a different mode. import ...
『PyTorch模型转ONNX』 ONNX is an open format built to represent machine learning models. ONNX defines a common set of operators - the building blocks of machine learning and deep learning models - and a common file format to enable AI developers to ...
Large-scale real-world GNN models: We focus on the need of GNN applications in challenging real-world scenarios, and support learning on diverse types of graphs, including but not limited to: scalable GNNs for graphs with millions of nodes; dynamic GNNs for node predictions over time; heterogen...
torch.compilepreviously only supported Python up to version 3.12. Users can now optimize models withtorch.compilein Python 3.13. [Beta] New packaging APIs for AOTInductor A new package format, “PT2 archive”, has been introduced. This essentially contains a zipfile of all the files that need...

The memory usage in PyTorch is extremely efficient compared to Torch or some of the alternatives. We've written custom memory allocators for the GPU to make sure that your deep learning models are maximally memory efficient. This enables you to train bigger deep learning models than before. ...

这里的F.relu类型为function,若再剥开一层,其实际包裹的函数类型为builtin_function_or_method,这也是真正完成运算的部分。这些部分通常使用 C++ 实现(如ATen)。至此我们知道,一个模型的运算部分由 autograd functions 组成,这些 autograd functions 内部定义了 forward,backward 用以描述前向和梯度反传的过程,组合后可...
