Load and connect a context
==========================

Once an [ArContext is defined](context_definition.md), it have to be connected to a pipeline.

# Load JSON configuration file

An [ArContext](../../argaze.md/#argaze.ArFeatures.ArContext) can be loaded from a JSON configuration file thanks to the [argaze.load](../../argaze.md/#argaze.load) package method.

Here is a JSON configuration file related to the [previously defined Example context](context_definition.md):

```json
{
    "my_context.Example": {
        "name": "My example context",
        "parameter": ...,
        "pipeline": "pipeline.json"
    }
}
```

Then, here is how to load the JSON file:

```python
import argaze

# Load ArContext
with argaze.load('./configuration.json') as ar_context:

    # Do something with ArContext
    ...
```

!!! note
    There is nothing to do to execute a loaded context as it is handled inside its own **__enter__** method.
