Returns the indices of the maximum value of all elements in the tensor.
Returns the indices of the maximum value of all elements in the tensor.
This is the second value returned by torch.max(). See its documentation for the exact semantics of this method.
Example:
val a = torch.rand(Seq(1, 3))
a.argmax()
// tensor dtype=float32, shape=[1] 2

Computes the gradient of current tensor w.r.t. graph leaves.
Computes the gradient of current tensor w.r.t. graph leaves.
The graph is differentiated using the chain rule. If the tensor is nonscalar (i.e. its data has more than one element) and requires gradient, the function additionally requires specifying gradient
. It should be a tensor of matching type and location, that contains the gradient of the differentiated function w.r.t. self
.
This function accumulates gradients in the leaves  you might need to zero .grad
attributes or set them to None
before calling it. See Default gradient layouts<defaultgradlayouts>
for details on the memory layout of accumulated gradients.
Note
If you run any forward ops, create gradient
, and/or call backward
in a userspecified CUDA stream context, see Stream semantics of backward passes<bwdcudastreamsemantics>
.
Note
When inputs
are provided and a given input is not a leaf, the current implementation will call its grad_fn (though it is not strictly needed to get this gradients). It is an implementation detail on which the user should not rely. See https://github.com/pytorch/pytorch/pull/60521#issuecomment867061780 for more details.

Compares the receiver object (this
) with the argument object (that
) for equivalence.
Compares the receiver object (this
) with the argument object (that
) for equivalence.
Any implementation of this method should be an equivalence relation:
 It is reflexive: for any instance
x
of typeAny
,x.equals(x)
should returntrue
.  It is symmetric: for any instances
x
andy
of typeAny
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
.  It is transitive: for any instances
x
,y
, andz
of typeAny
ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
.
If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode
to ensure that objects which are "equal" (o1.equals(o2)
returns true
) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)
).
Value parameters
 that

the object to compare against this object for equality.
Attributes
 Returns

true
if the receiver object is equivalent to the argument;false
otherwise.  Definition Classes

Returns a new view of this tensor with singleton dimensions expanded to a larger size.
Returns a new view of this tensor with singleton dimensions expanded to a larger size.
Passing 1 as the size for a dimension means not changing the size of that dimension.
Tensor can be also expanded to a larger number of dimensions, and the new ones will be appended at the front. For the new dimensions, the size cannot be set to 1.
Expanding a tensor does not allocate new memory, but only creates a new view on the existing tensor where a dimension of size one is expanded to a larger size by setting the stride
to 0. Any dimension of size 1 can be expanded to an arbitrary value without allocating new memory.
Value parameters
 sizes

the desired expanded size
Attributes
 Note

More than one element of an expanded tensor may refer to a single memory location. As a result, inplace operations (especially ones that are vectorized) may result in incorrect behavior. If you need to write to the tensors, please clone them first.
 Example

val x = torch.tensor((Seq(Seq(1), Seq(2), Seq(3))) x.size // [3, 1] x.expand(3, 4) x.expand(1, 4) // 1 means not changing the size of that dimension

is squeezed (see :func:torch.squeeze
