You can try using the CPU backend, or use old version like 0.6.10

Ok It works.Thank you for your valuable advice.

could you tell how to solve this problem ?
when test the eample ,the same question happened

“CUDA Error CUDA_ERROR_NOT_FOUND: named symbol not found while calling module_get_function (cuModuleGetFunction)”

use CPU backend: ti.init(arch=ti.cpu)

or use old version: python -m pip install taichi==0.6.10

thx a lot^_^,I have made it after changing the verison of chaichi
