 # Faster RCNN with PyTorch
+**Note:** I re-implemented faster rcnn in this project when I started learning PyTorch. Then I use PyTorch in all of my projects. I still remember it costed one week for me to figure out how to build cuda code as a pytorch layer :).
+But actually this is not a good implementation and I didn't achieve the same mIOU as the original caffe code. 
+
+**This project is no longer maintained. So I suggest:**
+- You can still read and study this code if you want to re-implement faster rcnn by yourself;
+- You can use the better PyTorch implementation by [ruotianluo](https://github.com/ruotianluo/pytorch-faster-rcnn) if you want to train faster rcnn with your own data;
+
 This is a [PyTorch](https://github.com/pytorch/pytorch)
 implementation of Faster RCNN. 
 This project is mainly based on [py-faster-rcnn](https://github.com/rbgirshick/py-faster-rcnn)
