## class Runs
```python theme={null}
(service_api: 'ServiceApi',
entity: 'str',
project: 'str',
filters: 'dict[str, Any] | None' = None,
order: 'str' = '+created_at',
per_page: 'int' = 50,
include_sweeps: 'bool' = False,
lazy: 'bool' = True,
api_key: 'str | None' = None)
```
## Description
A lazy iterator of `Run` objects associated with a project and optional filter.
Runs are retrieved in pages from the W\&B server as needed.
This is generally used indirectly using the `Api.runs` namespace.
## Args
* `service_api`: The service API to use for requests.
* `entity`: The entity (username or team) that owns the project.
* `project`: The name of the project to fetch runs from.
* `filters`: Filters to apply to the runs query.
* `order`: Order can be `created_at`, `heartbeat_at`, `config.*.value`, or `summary_metrics.*`. If you prepend order with a + order is ascending (default). If you prepend order with a - order is descending. The default order is run.created\_at from oldest to newest.
* `per_page`: The number of runs to fetch per request (default is 50).
* `include_sweeps`: Whether to include sweep information in the runs. Defaults to True.
* `lazy`:
* `api_key`:
## Methods
### method histories
```python theme={null}
self,
samples: 'int' = 500,
keys: 'list[str] | None' = None,
x_axis: 'str' = '_step',
format: "Literal['default', 'pandas', 'polars']" = 'default',
stream: "Literal['default', 'system']" = 'default'
```
Return sampled history metrics for all runs that fit the filters conditions.
##### Arguments
* `samples`: The number of samples to return per run
* `keys`: Only return metrics for specific keys
* `x_axis`: Use this metric as the xAxis defaults to \_step
* `format`: Format to return data in, options are "default", "pandas", "polars"
* `stream`: "default" for metrics, "system" for machine metrics
### method next
```python theme={null}
self
```
Return the next item from the iterator. When exhausted, raise StopIteration
### method update\_variables
```python theme={null}
self
```
Update the query variables for the next page fetch.
### method upgrade\_to\_full
```python theme={null}
self
```
Upgrade this Runs collection from lazy to full mode.
This switches to fetching full run data and
upgrades any already-loaded Run objects to have full data.
Uses parallel loading for better performance when upgrading multiple runs.
