Hi,
I have ported over the StackOverflowNER code over to Google colab. I fixed many small bugs and finally got it to work. Feel free to use the code in your own projects. You will need Colab Pro ($10/month) and Google Drive subscription to store the data.
You can find the project here: https://colab.research.google.com/drive/1_df1kTyPT_m65npDpuc1P8hmszqEa0aC?usp=sharing
Let me know if this helps!
