## Change History
|
||||
|
||||
* 2023/03/19 (v21.3.0)
|
||||
- Add a function to load training config with `.toml` to each training script. Thanks to Linaqruf for this great contribution!
|
||||
- Specify `.toml` file with `--config_file`. `.toml` file has `key=value` entries. Keys are same as command line options. See [#241](https://github.com/kohya-ss/sd-scripts/pull/241) for details.
|
||||
- All sub-sections are combined to a single dictionary (the section names are ignored.)
|
||||
- Omitted arguments are the default values for command line arguments.
|
||||
- Command line args override the arguments in `.toml`.
|
||||
- With `--output_config` option, you can output current command line options to the `.toml` specified with`--config_file`. Please use as a template.
|
||||
- Add `--lr_scheduler_type` and `--lr_scheduler_args` arguments for custom LR scheduler to each training script. Thanks to Isotr0py! [#271](https://github.com/kohya-ss/sd-scripts/pull/271)
|
||||
- Same as the optimizer.
|
||||
- Add sample image generation with weight and no length limit. Thanks to mio2333! [#288](https://github.com/kohya-ss/sd-scripts/pull/288)
|
||||
- `( )`, `(xxxx:1.2)` and `[ ]` can be used.
|
||||
- Fix exception on training model in diffusers format with `train_network.py` Thanks to orenwang! [#290](https://github.com/kohya-ss/sd-scripts/pull/290)
|
||||
- Add warning if you are about to overwrite an existing model: https://github.com/bmaltais/kohya_ss/issues/404
|
||||
* 2023/03/19 (v21.2.5):
|
||||
- Fix basic captioning logic
|
||||
- Add possibility to not train TE in Dreamboot by setting `Step text encoder training` to -1.
