all_dims: All dims

In rTorch: R Bindings to 'PyTorch'

Description

This function returns an object that can be used when subsetting tensors with [. If you are familiar with Python, this is equivalent to the Python Ellipsis ..., (not to be confused with ... in R). In Python, if x is a numpy array or a torch tensor, in x[..., i] the ellipsis means "expand to match number of dimension of x". To translate the above Python expression to R, write: x[all_dims(), i].

Usage

all_dims()

Examples

## Not run: 
# Run this
d <- torch$tensor(list(list(0, 0),
                       list(0, 0),
                       list(0, 1),
                       list(1, 1)), dtype=torch$uint8)
d[all_dims(), 1]

f <- torch$arange(9L)$reshape(c(3L, 3L))
f
f[all_dims()]
f[all_dims(), 1L]
