# TensorPlanKey

Tensor plan key.

Last updated: 2026-09-09

Package: compute.tensor | Status: source-declared

Tags: compute, compute.tensor, cpu, function, source-example, tensor, yeho

Represent tensor shapes, layouts, and numerical storage contracts.

```yh
external TensorPlanKey(text label, tensorShape shape, tensorPlacement placement, text executionPath) returns text
```


## Use TensorPlanKey

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.tensor

// Represent tensor shapes, layouts, and numerical storage contracts.
text label = "Player health"
tensorShape shape = tensorShape("element Type", [])
tensorPlacement placement = tensorPlacement("device", "memory")
text executionPath = "execution Path"
text result = TensorPlanKey(label, shape, placement, executionPath)
Console.Log(Text.From(result))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.compute_tensor__tensorplankey"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "compute.tensor"
version = "0.1.0"
path = "../../../yeho/packages/compute/tensor"

[[dependencies]]
package = "console"
version = "0.1.0"
path = "../../../yeho/packages/console"

[[dependencies]]
package = "diagnostics"
version = "0.1.0"
path = "../../../yeho/packages/diagnostics"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/compute.tensor--TensorPlanKey/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
