训练:Qwen-Image 系列模型支持 DeepSpeed ZeRO 3 训练,将模型拆分到多个 GPU 上,以 Qwen-Image 模型的全量训练为例,需修改: * `--config_file examples/qwen_image/model_training/full/accelerate_config_zero3.yaml` * `--initialize_model_on_cpu` ## 模型推理 模型通过 `QwenImagePipeline.from_pretrained` 加载,详见[加载模型](../Pipeline_Usage/Model_Inference.md#加载模型)。 `QwenImagePipeline` 推理的输入参数包括: * `prompt`: 提示词,描述画面中出现的内容。 * `negative_prompt`: 负向提示词,描述画面中不应该出现的内容,默认值为 `""`。 * `cfg_scale`: Classifier-free guidance 的参数,默认值为 4,当设置为 1 时不再生效。 * `input_image`: 输入图像,用于图生图,该参数与 `denoising_strength` 配合使用。 * `denoising_strength`: 去噪强度,范围是 0~1,默认值为 1,当数值接近 0 时,生成图像与输入图像相似;当数值接近 1 时,生成图像与输入图像相差更大。在不输入 `input_image` 参数时,请不要将其设置为非 1 的数值。 * `inpaint_mask`: 图像局部重绘的遮罩图像。 * `inpaint_blur_size`: 图像局部重绘的边缘柔化宽度。 * `inpaint_blur_sigma`: 图像局部重绘的边缘柔化强度。 * `height`: 图像高度,需保证高度为 16 的倍数。 * `width`: 图像宽度,需保证宽度为 16 的倍数。 * `seed`: 随机种子。默认为 `None`,即完全随机。 * `rand_device`: 生成随机高斯噪声矩阵的计算设备,默认为 `"cpu"`。当设置为 `cuda` 时,在不同 GPU 上会导致不同的生成结果。 * `num_inference_steps`: 推理次数,默认值为 30。 * `exponential_shift_mu`: 在采样时间步时采用的固定参数,留空则根据图像宽高进行采样。 * `blockwise_controlnet_inputs`: Blockwise ControlNet 模型的输入。 * `eligen_entity_prompts`: EliGen 分区控制的提示词。 * `eligen_entity_masks`: EliGen 分区控制的区域遮罩图像。 * `eligen_enable_on_negative`: 是否在 CFG 的负向一侧启用 EliGen 分区控制。 * `edit_image`: 编辑模型的待编辑图像,支持多张图像。 * `edit_image_auto_resize`: 是否自动缩放待编辑图像。 * `edit_rope_interpolation`: 是否在低分辨率编辑图像上启用 ROPE 插值。 * `context_image`: In-Context Control 的输入图像。 * `tiled`: 是否启用 VAE 分块推理,默认为 `False`。设置为 `True` 时可显著减少 VAE 编解码阶段的显存占用,会产生少许误差,以及少量推理时间延长。 * `tile_size`: VAE 编解码阶段的分块大小,默认为 128,仅在 `tiled=True` 时生效。 * `tile_stride`: VAE 编解码阶段的分块步长,默认为 64,仅在 `tiled=True` 时生效,需保证其数值小于或等于 `tile_size`。 * `progress_bar_cmd`: 进度条,默认为 `tqdm.tqdm`。可通过设置为 `lambda x:x` 来屏蔽进度条。 如果显存不足,请开启[显存管理](../Pipeline_Usage/VRAM_management.md),我们在示例代码中提供了每个模型推荐的低显存配置,详见前文“模型总览”中的表格。 ## 模型训练 Qwen-Image 系列模型统一通过 [`examples/qwen_image/model_training/train.py`](https://github.com/modelscope/DiffSynth-Studio/blob/main/examples/qwen_image/model_training/train.py) 进行训练,脚本的参数包括: * 通用训练参数 * 数据集基础配置 * `--dataset_base_path`: 数据集的根目录。 * `--dataset_metadata_path`: 数据集的元数据文件路径。 * `--dataset_repeat`: 每个 epoch 中数据集重复的次数。 * `--dataset_num_workers`: 每个 Dataloder 的进程数量。 * `--data_file_keys`: 元数据中需要加载的字段名称,通常是图像或视频文件的路径,以 `,` 分隔。 * 模型加载配置 * `--model_paths`: 要加载的模型路径。JSON 格式。 * `--model_id_with_origin_paths`: 带原始路径的模型 ID,例如 `"Qwen/Qwen-Image:transformer/diffusion_pytorch_model*.safetensors"`。用逗号分隔。 * `--extra_inputs`: 模型 Pipeline 所需的额外输入参数,例如训练图像编辑模型 Qwen-Image-Edit 时需要额外参数 `edit_image`,以 `,` 分隔。 * `--fp8_models`:以 FP8 格式加载的模型,格式与 `--model_paths` 或 `--model_id_with_origin_paths` 一致,目前仅支持参数不被梯度更新的模型(不需要梯度回传,或梯度仅更新其 LoRA)。 * 训练基础配置 * `--learning_rate`: 学习率。 * `--num_epochs`: 轮数(Epoch)。 * `--trainable_models`: 可训练的模型,例如 `dit`、`vae`、`text_encoder`。 * `--find_unused_parameters`: DDP 训练中是否存在未使用的参数,少数模型包含不参与梯度计算的冗余参数,需开启这一设置避免在多 GPU 训练中报错。 * `--weight_decay`:权重衰减大小,详见

`--lora_rank`: LoRA 的秩(Rank)。 * `--lora_checkpoint`: LoRA 检查点的路径。如果提供此路径,LoRA 将从此检查点加载。 * `--preset_lora_path`: 预置 LoRA 检查点路径,如果提供此路径,这一 LoRA 将会以融入基础模型的形式加载。此参数用于 LoRA 差分训练。 * `--preset_lora_model`: 预置 LoRA 融入的模型,例如 `dit`。 * 梯度配置 * `--use_gradient_checkpointing`: 是否启用 gradient checkpointing。 * `--use_gradient_checkpointing_offload`: 是否将 gradient checkpointing 卸载到内存中。 * `--gradient_accumulation_steps`: 梯度累积步数。 * 图像宽高配置(适用于图像生成模型和视频生成模型) * `--height`: 图像或视频的高度。将 `height` 和 `width` 留空以启用动态分辨率。 * `--width`: 图像或视频的宽度。将 `height` 和 `width` 留空以启用动态分辨率。 * `--max_pixels`: 图像或视频帧的最大像素面积,当启用动态分辨率时,分辨率大于这个数值的图片都会被缩小,分辨率小于这个数值的图片保持不变。 * Qwen-Image 专有参数 * `--tokenizer_path`: tokenizer 的路径,适用于文生图模型,留空则自动从远程下载。 * `--processor_path`: processor 的路径,适用于图像编辑模型,留空则自动从远程下载。 我们构建了一个样例图像数据集,以方便您进行测试,通过以下命令可以下载这个数据集: ```shell modelscope download --dataset DiffSynth-Studio/example_image_dataset --local_dir ./data/example_image_dataset ``` 我们为每个模型编写了推荐的训练脚本,请参考前文“模型总览”中的表格。关于如何编写模型训练脚本,请参考[模型训练](../Pipeline_Usage/Model_Training.md);更多高阶训练算法,请参考[训练框架详解](https://github.com/modelscope/DiffSynth-Studio/tree/main/docs/zh/Training/)。
