Thank you for your reply!
I tried to build the model directly without running AutoTVM and it can run normally. But when I used autotvm to tune conv2d, the program always reported this error even if I set n_trial to 5000. To reproduce the problem, I modified the code: [incubator-tvm](https://github.com/apache/incubator-tvm)/[tutorials](https://github.com/apache/incubator-tvm/tree/master/tutorials)/[autotvm](https://github.com/apache/incubator-tvm/tree/master/tutorials/autotvm)/ **tune_conv2d_cuda.py** Compared with the source program, I made the following modifications: 1. add "from tvm.contrib import nvcc" in line 50; 2. add "test_tensorcore=nvcc.have_tensorcore(tvm.gpu(0).compute_version)" in line 90; 3. modify n_trial=2000 in line 200. If I delete the "test_tensorcore=nvcc.have_tensorcore(tvm.gpu(0).compute_version)", the autotvm can run normally. --- [Visit Topic](https://discuss.tvm.ai/t/autotvm-error-cudaerrorcudartunloading-initialization-error-error-no-2/6487/3) to respond.
