Hi
I did a fresh install of Taichi on my Win10 system. I used CMake + MSVC to generate and compile the solution. However, I have some errors when I try to run any example provided with the lib. I’m not sure where the error comes from. I installed all the Python dependencies listed in the doc + clang-10 + LLVM-10.0.0. Note that for LLVM, I tried to use both pre-built binaries available on Taichi’s website and some binaries I generated by compiling the source code. Thank you very much for your help.
D:\Dev\taichi> python .\examples\mpm128.py
