Error Converting pt. FIle to Blob

Ttmereinhart · Aug 10, 2023

Hi,

Using the tools.luxonis.com, i am getting an error when attempting to convert a .pt file to a .blob file.

The function used to work a month ago or so. I tested an old .pt file and it currently converts correctly. However, if I create a new .pt file, i get errors, even using the same data as before.

So basically, I follow the Ultralytics YOLOv8 colab notebook, first installing files, then training to my custom dataset. I download the outputted best.pt and use the tools.luxonis.com to convert. Is there any chance some versions are updated and now causing the tool not to work?

Thanks, Tim

Update: I am successful with a previous version of Ultralytics YoloV8. For example im running pip install ultralytics==8.0.120.

Is there a chance the blob converter doesn't work for YoloV8.0.151?

Yes, tools.luxonis.com currently uses the source code of Yolov8.0.114, and ultralytics has modified some code structures in the new version, so that the old version cannot load the new model. You can use an earlier version of Ultralytics YoloV8 or refer to the article about converting YOLOv8 model to blob format to convert it yourself
