+# Train and test
+* charcoal_style for systhesising charcoal style images,it contains **sRender w/o Lstr** for model without stroke_loss and **sRender** for model with stroke_loss correspodingly
+* croquis_style for systhesising croquis style images,it contains **sRenderPix2Pix**,**sRender w/o Lstr** and **sRender**
+* download dataset [gray](https://drive.google.com/drive/folders/1ZuRVlPwvtNtfkNIj-DIdi2kr-1kEcPhg?usp=sharing) for **charcol_style**, [binary](https://drive.google.com/drive/folders/1VBUBdGWz324dhCu8LRFU5qB0PqXxNQIJ?usp=sharing) for **croquis_style**
+* download pretrain model and put them in **./checkpoints** for test
+* for model with stroke_loss,you should download [stroke_model](https://drive.google.com/file/d/16gSERA3TbPVFyCvKGtNKtJrQaOsG8vmO/view?usp=sharing) and specify model root in
+  **./models/pix2pixHD_model** for **net_c.load_state_dict**
+* you can modify **options/base_option** to specify **--dataroot**, then run train.py or test.py
