File "/usr/local/lib/python3.12/dist-packages/nvidia_cutlass_dsl/python_packages/cutlass/cutlass_dsl/cuda_jit_executor.py", line 126, in num_devices
raise DSLCudaRuntimeError(dev_err, cuda_runtime.cudaGetErrorName(dev_err))
cutlass.base_dsl.common.DSLCudaRuntimeError: DSLCudaRuntimeError: (<cudaError_t.cudaSuccess: 0>, b'cudaErrorInsufficientDriver') (error code: 35)

Error Code: 35

🔍 Additional Context:

  • Error name: (<cudaError_t.cudaSuccess: 0>, b'cudaErrorInsufficientDriver')
  • Error code: 35
  • CUDA_TOOLKIT_PATH: not set
  • Target SM ARCH: not set

📊 GPU Information:

  • CUDA devices available: 8 (current: <CUdevice 6>)
  • Architecture: Blackwell (sm_100a)
  • Compatible SM archs: sm_100a
  • Total Memory: 178.36 GB

Compatibility Check:
❌ Error: Target SM ARCH unknown is not compatible
💡 Please use one of SM ARCHs: sm_100a
