### Register model
Supported models:
@ -557,6 +896,85 @@ datum explain \
-s 1000 --progressive
```
### Transform Project
This command allows to modify images or annotations in a project all at once.
``` bash
datum project transform --help
datum project transform \
-p <project_dir> \
-o <output_dir> \
-t <transform_name> \
-- [extra transform options]
```
Example: split a dataset randomly to `train` and `test` subsets, ratio is 2:1
``` bash
datum project transform -t random_split -- --subset train:.67 --subset test:.33
```
Example: convert polygons to masks, masks to boxes etc.:
``` bash
datum project transform -t boxes_to_masks
datum project transform -t masks_to_polygons
datum project transform -t polygons_to_masks
datum project transform -t shapes_to_boxes
```
Example: remap dataset labels, `person` to `car` and `cat` to `dog`, keep `bus`, remove others
``` bash
datum project transform -t remap_labels -- \
-l person:car -l bus:bus -l cat:dog \
--default delete
```
Example: rename dataset items by a regular expression
- Replace `pattern` with `replacement`
- Remove `frame_` from item ids
``` bash
datum project transform -t rename -- -e '|pattern|replacement|'
datum project transform -t rename -- -e '|frame_(\d+)|\\1|'
```
## Extending
There are few ways to extend and customize Datumaro behaviour, which is supported by plugins.
Check [our contribution guide](../CONTRIBUTING.md) for details on plugin implementation.
In general, a plugin is a Python code file. It must be put into a plugin directory:
- `<project_dir>/.datumaro/plugins` for project-specific plugins
- `<datumaro_dir>/plugins` for global plugins
### Dataset Formats
Dataset reading is supported by Extractors and Importers.
An Extractor produces a list of dataset items corresponding
to the dataset. An Importer creates a project from the data source location.
It is possible to add custom Extractors and Importers. To do this, you need
to put an Extractor and Importer implementation scripts to a plugin directory.
Dataset writing is supported by Converters.
A Converter produces a dataset of a specific format from dataset items.
It is possible to add custom Converters. To do this, you need to put a Converter
implementation script to a plugin directory.
### Dataset Conversions ("Transforms")
A Transform is a function for altering a dataset and producing a new one. It can update
dataset items, annotations, classes, and other properties.
A list of available transforms for dataset conversions can be extended by adding a Transform
implementation script into a plugin directory.
### Model launchers
A list of available launchers for model execution can be extended by adding a Launcher
implementation script into a plugin directory.
