**Hi everyone,**
I’m new to Roboflow and have just completed annotating my dataset. However, when I attempted to train my dataset, I noticed that the **YOLOv8 instance segmentation** training option is not available on Roboflow as of 2025.
The platform only provides the following training options:
- **Roboflow 3.0**
- **YOLOv11**
- **YOLOv12**
- **YOLO-NAS**
My dataset consists of **both bounding boxes (object detection) and segmentation masks (instance segmentation)**. However, after training with **YOLOv12** , my model only displays **bounding boxes** , and the **segmentation masks are not shown** during object detection in videos.
Does Roboflow provide **YOLOv8 segmentation weights (.pt)** anywhere else, or is there an alternative way to train and deploy **YOLOv8 instance segmentation** within Roboflow for a mixed labelled dataset that contains both rectangle and polygon bounding boxes in a Instance Segmentation Roboflow project?
Any guidance on how to fix this issue would be greatly appreciated!

hi;
if you want see you traing and the code you can try to download dataset than choose your format than click on show code … than check on show code on colab

Hey there - it looks like you have an Object Detection project in the Roboflow App - you’d need to duplicate it first as an Instance Segmentation project in order to train it as an Instance Segmentation model.
You can do that inside the app:
1. Go to your projects home, find the project you want to duplicate and click on the three dots
2. Click on **Duplicate Project**
3. Select the new project name and type - there you will need to choose Instance Segmentation
There you go, just go and train your model.
