Hi! Thanks for your great work!

I’m interested in task graph construction. However, I could not find the task graph data mentioned in 13.B.3 of the arXiv paper’s appendix (I copied the corresponding part in this comment).  
It would help me greatly if you could direct me to where I can obtain the task graph.

Hi, may I ask if you obtain the task graghs please?

Not yet, unfortunately.

Thank you all the same. I’m now emailing the team. If there is any response, I will share with you.
