Loading modules from another package
====================================
It possible to load [GazeMovementIdentifier](../../../argaze.md/#argaze.GazeFeatures.GazeMovementIdentifier), [ScanPathAnalyzer](../../../argaze.md/#argaze.GazeFeatures.ScanPathAnalyzer), [AOIMatcher](../../../argaze.md/#argaze.GazeFeatures.AOIMatcher) or [AOIScanPathAnalyzer](../../../argaze.md/#argaze.GazeFeatures.AOIScanPathAnalyzer) modules from another [python package](https://docs.python.org/3/tutorial/modules.html#packages).
To do so, simply prepend the package where to find the module into the JSON configuration file:
```
{
...
"gaze_movement_identifier": {
"my_package.MyGazeMovementIdentifierAlgorithm": {
"specific_plugin_parameter": 0
}
},
...
"scan_path_analyzers": {
"my_package.MyScanPathAnalyzerAlgorithm": {
"specific_plugin_parameter": 0
}
}
...
"aoi_matcher": {
"my_package.MyAOIMatcherAlgorithm": {
"specific_plugin_parameter": 0
}
}
...
"aoi_scan_path_analyzers": {
"my_package.MyAOIScanPathAnalyzerAlgorithm": {
"specific_plugin_parameter": 0
}
}
}
```
Then, load your package from the python script where the [ArFrame](../../../argaze.md/#argaze.ArFeatures.ArFrame) is created.
```python
from argaze import ArFeatures
# Import your own package
import my_package
# Load ArFrame
ar_frame = ArFeatures.ArFrame.from_json('./configuration.json')
# Print ArFrame attributes
for module, scan_path_analyzer in ar_frame.scan_path_analyzers.items():
print('scan path analyzer type:', type(scan_path_analyzer))
```
