+# Segformer B2 fine-tuned for clothes segmentation
+
+SegFormer model fine-tuned on [ATR dataset](https://github.com/lemondan/HumanParsing-Dataset) for clothes segmentation but can also be used for human segmentation.
+The dataset on hugging face is called "mattmdjaga/human_parsing_dataset".
+
+**[Training code](https://github.com/mattmdjaga/segformer_b2_clothes)**.
+```python
+from transformers import SegformerImageProcessor, AutoModelForSemanticSegmentation
+from PIL import Image
+import requests
+import matplotlib.pyplot as plt
+import torch.nn as nn
+
+processor = SegformerImageProcessor.from_pretrained("mattmdjaga/segformer_b2_clothes")

+
+image = Image.open(requests.get(url, stream=True).raw)

+    logits,
+    size=image.size[::-1],
+    mode="bilinear",
+    align_corners=False,
+)
+
+pred_seg = upsampled_logits.argmax(dim=1)[0]
