31.12.2021 · 🐛 Describe the bug When scripting a class which relies on torch.Tensor.bool, the method is not found and errors out with 'Tensor' object has no attribute or method 'bool'.. import torch class Bar: def __init__(self, x: torch.Tensor): sel...

The following are 30 code examples for showing how to use torch.bool().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

Isn't this more economical (albeit longer): a = torch.zeros(10, dtype=torch.bool). or, in older versions, a = torch.zeros(10, ...

Tensors can be defined as either an integer, floating-point or a boolean value (Figure 1). Torch defines nine tensor types.

One dimensional vector is created using the torch.tensor() method. ... a = torch.tensor([ 100 , 200 , 2 , 3 , 4 ], dtype = torch. bool ).

torch.logical_and(input, other, *, out=None) → Tensor. Computes the element-wise logical AND of the given input tensors. Zeros are treated as False and nonzeros are treated as True. Parameters. input ( Tensor) – the input tensor. other ( Tensor) – the tensor to compute AND with. Keyword Arguments. out ( Tensor, optional) – the output ...

A torch.Tensor is a multi-dimensional matrix containing elements of a single data type. Data types. Torch defines 10 tensor types with CPU and GPU variants ...

If keepdim is True, the output tensor is of the same size as input except in the dimension dim where it is of size 1. Otherwise, dim is squeezed (see torch.squeeze()), resulting in the output tensor having 1 fewer dimension than input. Parameters. input – the input tensor. dim – the dimension to reduce.

12.03.2019 · I found a behavior that I could not completely explain in boolean indexing. While it works fine with a tensor >>> a = torch.tensor([[1,2],[3,4]]) >>> a[torch.tensor([[True,False],[False,True]])] tensor([1, 4]) It does not work with a list of booleans >>> a[[[True,False],[False,True]]] tensor([3, 2]) My best guess is that in the second case the bools …

BoolTensor actually uses a byte for each element instead of a bit. To Reproduce. Steps to reproduce the behavior: import torch x = torch.

torch.any. input ( Tensor) – the input tensor. Tests if any element in input evaluates to True. This function matches the behaviour of NumPy in returning output of dtype bool for all supported dtypes except uint8 . For uint8 the dtype of output is uint8 itself. For each row of input in the given dimension dim , returns True if any element in ...

Lifeng_Jin (Lifeng Jin) August 2, 2017, 3:23pm #1. Is it known that if you do torch.sum(y_hat == y), if the sum is larger than 255, the sum will be whatever - 255? I am seeing this ...

torch.logical_or(input, other, *, out=None) → Tensor. Computes the element-wise logical OR of the given input tensors. Zeros are treated as False and nonzeros are treated as True. Parameters. input ( Tensor) – the input tensor. other ( Tensor) – the tensor to compute OR with. Keyword Arguments. out ( Tensor, optional) – the output tensor.

这个函数的作用是将该tensor转换为另一个tensor的type,可以同步完成转换CPU类型和GPU类型，如torch.IntTensor-->torch.cuda.floatTendor. 如果张量已经是指定类型，则不会进行转换. t1=torch.Tensor(2,3) t2=torch.IntTensor(3,5) t3=t1.type_as(t2) print(t3.type()) torch.IntTensor. 发布于 2019-05-04 18:40 ...
