If you want to train, validate or run inference on models and don't need to make any modifications to the code, using
|
|
YOLO command line interface is the easiest way to get started.
|
|
|
|
!!! tip "Syntax"
|
|
|
|
```bash
|
|
yolo task=detect mode=train model=yolov8n.yaml epochs=1 ...
|
|
... ... ...
|
|
segment predict yolov8n-seg.pt
|
|
classify val yolov8n-cls.pt
|
|
```
|
|
|
|
The experiment arguments can be overridden directly by pass `arg=val` covered in the next section. You can run any
|
|
supported task by setting `task` and `mode` in cli.

## Overriding default config arguments
|
|
|
|
All global default arguments can be overriden by simply passing them as arguments in the cli.
|
|
|
|
!!! tip ""
|
|
|
|
=== "Syntax"
|
|
```bash
|
|
yolo task= ... mode= ... {++ arg=val ++}
|
|
```
|
|
|
|
=== "Example"
|
|
Perform detection training for `10 epochs` with `learning_rate` of `0.01`
|
|
```bash
|
|
yolo task=detect mode=train {++ epochs=10 lr0=0.01 ++}
|
|
```
|
|

## Overriding default config file
|
|
|
|
You can override config file entirely by passing a new file. You can create a copy of default config file in your
|
|
current working dir as follows:
|
|
|
|
```bash
|
|
yolo task=init
|
|
```
|
|
|
|
You can then use `cfg=name.yaml` command to pass the new config file
|
|
|
|
```bash
|
|
yolo cfg=default.yaml
|
|
```
|
|
|
|
??? example
|
|
|
|
=== "Command"
|
|
```bash
|
|
yolo task=init
|
|
yolo cfg=default.yaml
|
|
```
