 ## Updates
+**Oct 25, 2021**
+
+We release a CodeT5-base fine-tuned checkpoint ([Salesforce/codet5-base-multi-sum](https://huggingface.co/Salesforce/codet5-base-multi-sum)) for multi-lingual code summarzation. Below is how to use this model:
+
+```python
+from transformers import RobertaTokenizer, T5ForConditionalGeneration
+
+if __name__ == '__main__':
+    tokenizer = RobertaTokenizer.from_pretrained('Salesforce/codet5-base')
+    model = T5ForConditionalGeneration.from_pretrained('Salesforce/codet5-base-multi-sum')
+
+    text = """def svg_to_image(string, size=None):
+    if isinstance(string, unicode):
+        string = string.encode('utf-8')
+        renderer = QtSvg.QSvgRenderer(QtCore.QByteArray(string))
+    if not renderer.isValid():
+        raise ValueError('Invalid SVG data.')
+    if size is None:
+        size = renderer.defaultSize()
+        image = QtGui.QImage(size, QtGui.QImage.Format_ARGB32)
+        painter = QtGui.QPainter(image)
+        renderer.render(painter)
+    return image"""
+
+    input_ids = tokenizer(text, return_tensors="pt").input_ids
+
+    generated_ids = model.generate(input_ids, max_length=20)
+    print(tokenizer.decode(generated_ids[0], skip_special_tokens=True))
+    # this prints: "Convert a SVG string to a QImage."
+```
+
+It significantly outperforms previous methods on code summarization in the [CodeXGLUE benchmark](https://github.com/microsoft/CodeXGLUE/tree/main/Code-Text/code-to-text):
