Hi, it would be helpful if you can also attach a minimal example to reproduce the above error. thanks!

#3

Hi, @yjhp1016 , may I check what version of Taichi did you use? ( I am asking for this because the error shown here looks like a known issue in the previous Taichi version

Could you please update Taichi to the latest version and give an other try? Thanks.

#4

Hi @mzhang @qiao-bo , I was using 0.8.11 before, now I updated taichi to latest 0.9.0, still got similar error, but slightly different: RuntimeError: [ir.h:as@209] Assertion failure: is()

I don’t have a small example to reproduce this error, but I would be happy to share my code in private with you, if that will help :grinning:

Thank you!

Sure. I am willing to help. :grinning:
