lazy_tensor function

Create a lazy tensor

Create a lazy tensor.

lazy_tensor(data_descriptor = NULL, ids = NULL)

Arguments

• data_descriptor: (DataDescriptor or NULL)

  The data descriptor or NULL for a lazy tensor of length 0.

• ids: (integer())

  The elements of the data_descriptor to be included in the lazy tensor.

Examples

ds = dataset("example",
  initialize = function() self$iris = iris[, -5],
  .getitem = function(i) list(x = torch_tensor(as.numeric(self$iris[i, ]))),
  .length = function() nrow(self$iris)
)()
dd = as_data_descriptor(ds, list(x = c(NA, 4L)))
lt = as_lazy_tensor(dd)
