确认torch_sparse库的导入方式是否正确: 正确的导入方式应该是: python import torch_sparse 你提到的 from torch_sparse import sparsetensor 是不正确的,因为torch_sparse库中没有直接名为sparsetensor的模块或函数。如果你需要创建一个稀疏张量,应该使用torch_sparse库提供的相关函数,例如torch_sparse.SparseTensor(...
When running my code through a docker container, where sparse_csc_tensor is being imported I am getting the following ImportError. I am not sure if this is due to the version that I am using of torch. I currently use Torch==1.11.0 in my docker container. I would appreciate any help y...
The reason to useTensordirectly compared totorch.Tensoris an attempt to have lower cost of this function. Let's take a look at what I think is about the average case of 16 inputs to the fusion: In[1]:importtorch In[2]:fromtorchimportTensor In[3]:args=[torch.ones((2,2))for_inra...

在PyTorch中,当我们使用torch.jit.trace函数对模型进行跟踪时,可能会遇到一个错误消息:Only tensors or tuples of tensors can be output from traced functions(只有张量或张量元组可以从跟踪函数中输出)。本文将详细讲解这个错误消息的含义以及如何解决它。
