Nvidia Cuda Toolkit 12.6 <Updated × 2025>

/usr/local/cuda-12.6/extras/demo_suite/deviceQuery Should show your GPU and Result = PASS . Download from NVIDIA cuDNN archive (requires login). Example for cuDNN 9.x compatible with CUDA 12.6:

cd ~ cat > test.cu << EOF #include <stdio.h> int main() printf("CUDA version: %d\n", __CUDACC_VER__); return 0; nvidia cuda toolkit 12.6

Check current driver:

export PATH=/usr/local/cuda-12.6/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-12.6/lib64:$LD_LIBRARY_PATH export CUDA_HOME=/usr/local/cuda-12.6 Then: /usr/local/cuda-12

Compile and run a test:
