Project type: Object detection  
OS: Ubuntu 18.04  
Browser: Google Chrome  
Problem:

Attempting to use the Google Colab: [Google Colab](https://colab.research.google.com/drive/1fPn9WJQp_4dX1JfQNiBImcDwtEk_qa1b#scrollTo=gnNXNQCjdniL)  
To create a .blob file to use with an OAK-D camera

Google Colab no longer supports tensorflowV1. The colab prompts me to install V1, but colab won’t allow it. Unfortunately, the line

!python3 convert\_weights\_pb.py --weights\_file /content/darknet/backup/custom-yolov3-tiny-detector\_best.weights --class\_names /content/darknet/data/obj.names --data\_format NHWC --tiny

requires tensorflowV1.

I have tried using pip as a work around to install tensorflowV1, but still get errors. I have tried using tensorflowV2, but get errors with the convert\_weights\_pb.py requiring version 1.

Hi, I also need a blob file from a Roboflow project. I wonder if you found any solution for that?

Project has been put on the low priority list for me, so I have not found a solution yet.
