I am converting a jagged nested tensor to a padded tensor, then adding Rotary positional embeddings, then converting it back to a jagged tensor. The forward pass is just fine, but the backwards pass breaks. It is probably because the offsets object changes throughout the forward pass, but I...
Nested tensors are a great way to handle a batch of sequences with different lengths, which is often the case in NLP or ViTs for images of very different resolutions. Often, you add acls_tokento the input tensor as the first token, which currently (awaik) is not straightforward with ne...

foreach是torch.optim的优化,在算子创建时,使用一个kernel操作一系列的tensors。 这在scheduler创建node节点时,就会创建foreach类的节点。 该类型节点的融合,codegen都和其他类型不同。 该类型节点不做深入分析。 3.2.4 is_template if node.is_template(): node, *epilogue = node.get_nodes() self.get_backen...

如果list是一个嵌套list,那么生成的tensor将是多维的。 python # 指定数据类型 my_tensor_float = torch.tensor(my_list, dtype=torch.float32) # 输出结果以验证 print(my_tensor_float) # 输出: tensor([1., 2., 3., 4., 5.], dtype=torch.float32) # 多维tensor的例子 nested_list = [[1, 2...
Neural networks (NNs) are a collection of nested functions that are executed on some input data. These functions are defined by parameters (consisting of weights and biases), which in PyTorch are stored in tensors. Training a NN happens in two steps: ...
🚀 The feature, motivation and pitch In the case of 4 dimensions, we should additionally check that the size(1)==1. This is because for us to use torch.bmm for segment_matmul, we split a tensor of shape (x, y, z) and we get a list of x te...
