### 模型训练
### 模型训练
**下载预训练模型:**
本示例提供以下预训练模型:

下载完预训练模型之后,通过设置infer.py中
`--init_model`
加载预训练模型,测试所需要的图片。
执行以下命令得到CyleGAN的预测结果:
python infer.py \
--model_net=CycleGAN \
--init_model=$(path_to_init_model) \
--image_size=256 \
--dataset_dir=$(path_to_data) \
--input_style=$(A_or_B) \
--net_G=$(generator_network) \
--g_base_dims=$(base_dim_of_generator)
效果如图所示:

用户可以通过设置model_net参数来选择想要训练的模型,通过设置dataset参数来选择训练所需要的数据集。
-
可选参数见:
python train.py --help
-
每个GAN都给出了一份运行示例,放在scripts文件夹内,用户可以直接运行训练脚本快速开始训练。
