ggml_cpy: Copy Tensor with Type Conversion (Graph)

Description

Copies tensor a into tensor b, performing type conversion if needed. The tensors must have the same number of elements. CRITICAL for type casting operations (e.g., F32 to F16).

Usage

ggml_cpy(ctx, a, b)

Value

Tensor representing the copy operation (returns b with a's data)

Arguments

ctx

GGML context

a

Source tensor

b

Destination tensor (defines output type and shape)

Examples

# \donttest{
ctx <- ggml_init(16 * 1024 * 1024)
# Create F32 tensor
a <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 100)
ggml_set_f32(a, rnorm(100))
# Create F16 tensor for output
b <- ggml_new_tensor_1d(ctx, GGML_TYPE_F16, 100)
# Copy with F32 -> F16 conversion
result <- ggml_cpy(ctx, a, b)
graph <- ggml_build_forward_expand(ctx, result)
ggml_graph_compute(ctx, graph)
ggml_free(ctx)
# }
