### Working in progress
253
+
254
+
- The log output has been improved. PR [#905](https://github.com/kohya-ss/sd-scripts/pull/905) Thanks to shirayu!
255
+
- The log is formatted by default. The `rich` library is required. Please see [Upgrade](#upgrade) and update the library.
256
+
- If `rich` is not installed, the log output will be the same as before.
257
+
- The following options are available in each training script:
258
+
-`--console_log_simple` option can be used to switch to the previous log output.
259
+
-`--console_log_level` option can be used to specify the log level. The default is `INFO`.
260
+
-`--console_log_file` option can be used to output the log to a file. The default is `None` (output to the console).
261
+
- The sample image generation during multi-GPU training is now done with multiple GPUs. PR [#1061](https://github.com/kohya-ss/sd-scripts/pull/1061) Thanks to DKnight54!
262
+
- The IPEX support is improved. PR [#1086](https://github.com/kohya-ss/sd-scripts/pull/1086) Thanks to Disty0!
263
+
- Fixed a bug that `svd_merge_lora.py` crashes in some cases. PR [#1087](https://github.com/kohya-ss/sd-scripts/pull/1087) Thanks to mgz-dev!
264
+
- The common image generation script `gen_img.py` for SD 1/2 and SDXL is added. The basic functions are the same as the scripts for SD 1/2 and SDXL, but some new features are added.
265
+
- External scripts to generate prompts can be supported. It can be called with `--from_module` option. (The documentation will be added later)
266
+
- The normalization method after prompt weighting can be specified with `--emb_normalize_mode` option. `original` is the original method, `abs` is the normalization with the average of the absolute values, `none` is no normalization.
267
+
- Gradual Latent Hires fix is added to each generation script. See [here](./docs/gen_img_README-ja.md#about-gradual-latent) for details.
- Fixed a bug that the training crashes when `--fp8_base` is specified with `--save_state`. PR [#1079](https://github.com/kohya-ss/sd-scripts/pull/1079) Thanks to feffy380!
Gradual Latent is a Hires fix that gradually increases the size of the latent. `gen_img.py`, `sdxl_gen_img.py`, and `gen_img_diffusers.py` have the following options.
461
+
462
+
-`--gradual_latent_timesteps`: Specifies the timestep to start increasing the size of the latent. The default is None, which means Gradual Latent is not used. Please try around 750 at first.
463
+
-`--gradual_latent_ratio`: Specifies the initial size of the latent. The default is 0.5, which means it starts with half the default latent size.
464
+
-`--gradual_latent_ratio_step`: Specifies the ratio to increase the size of the latent. The default is 0.125, which means the latent size is gradually increased to 0.625, 0.75, 0.875, 1.0.
465
+
-`--gradual_latent_ratio_every_n_steps`: Specifies the interval to increase the size of the latent. The default is 3, which means the latent size is increased every 3 steps.
466
+
467
+
Each option can also be specified with prompt options, `--glt`, `--glr`, `--gls`, `--gle`.
468
+
469
+
__Please specify `euler_a` for the sampler.__ Because the source code of the sampler is modified. It will not work with other samplers.

It is more effective with SD 1.5. It is quite subtle with SDXL.
