In ggmlR: 'GGML' Tensor Operations for Machine Learning

Sum (Graph)

Description

Creates a graph node that computes the sum of all elements.

Usage

ggml_sum(ctx, a)

Arguments

ctx	GGML context
a	Input tensor

Value

Scalar tensor with the sum

Examples

ctx <- ggml_init(16 * 1024 * 1024)
a <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 5)
ggml_set_f32(a, c(1, 2, 3, 4, 5))
result <- ggml_sum(ctx, a)
graph <- ggml_build_forward_expand(ctx, result)
ggml_graph_compute(ctx, graph)
output <- ggml_get_f32(result)  # 15
ggml_free(ctx)
