# CreateGraphCheckpointPolicy

Create graph checkpoint policy from the supplied values.

Package: compute.graph | Status: source-declared

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

Describe compute work as an explicit graph with package-owned validation and scheduling metadata.

```yh
external CreateGraphCheckpointPolicy(text key, text format, text location, bool includeModelState, bool includeOptimizerState, bool includeRngState, int keepLatestCount, text note) returns graphCheckpointPolicy
```


## Use CreateGraphCheckpointPolicy

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

Verification: type checked

```yh
using compute.graph

// Describe compute work as an explicit graph with package-owned validation and scheduling metadata.
text key = "key"
text format = "png"
text location = "location"
bool includeModelState = true
bool includeOptimizerState = true
bool includeRngState = true
int keepLatestCount = 1
text note = "note"
graphCheckpointPolicy result = CreateGraphCheckpointPolicy(key, format, location, includeModelState, includeOptimizerState, includeRngState, keepLatestCount, note)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

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.graph--CreateGraphCheckpointPolicy/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.
