hi, could you please provide the full error information?
BTW, which Taichi version did you use?

@lshengjian Thanks for reporting this. The issue is caused by a minor behavior change after Taichi AST refactor. The code has been updated to fit the latest Taichi version. Please try to use the updated code.
