TypeError: auto_scheduler.RPCRunner is not registered via TVM_REGISTER_NODE_TYPE

Hello, while building the tune_network_cuda.py ( Auto-scheduling a Neural Network for NVIDIA GPU)in TVM , I got the following error: TypeError: auto_scheduler.RPCRunner is not registered via TVM_REGISTER_NODE_TYPE

Traceback (most recent call last): File “/tvm/tune_network_cuda.py”, line 201, in run_tuning() File “/tvm/tune_network_cuda.py”, line 192, in run_tuning runner=measure_ctx.runner, File “/root/.local/lib/python3.8/site-packages/tvm-0.8.dev987+g21a7b498b-py3.8-linux-x86_64.egg/tvm/runtime/object.py”, line 63, in getattr return _ffi_node_api.NodeGetAttr(self, name) File “tvm/_ffi/_cython/./packed_func.pxi”, line 322, in tvm._ffi._cy3.core.PackedFuncBase.call File “tvm/_ffi/_cython/./packed_func.pxi”, line 257, in tvm._ffi._cy3.core.FuncCall File “tvm/_ffi/_cython/./packed_func.pxi”, line 246, in tvm._ffi._cy3.core.FuncCall3 File “tvm/_ffi/_cython/./base.pxi”, line 160, in tvm._ffi._cy3.core.CALL TypeError: Traceback (most recent call last): 3: TVMFuncCall 2: _ZNSt17_Function_handlerI 1: tvm::NodeGetAttr(tvm::runtime::TVMArgs, tvm::runtime::TVMRetValue*) 0: tvm::ReflectionVTable::GetAttr(tvm::runtime::Object*, tvm::runtime::String const&) const File “/root/tvm/include/tvm/node/reflection.h”, line 390 TypeError: auto_scheduler.RPCRunner is not registered via TVM_REGISTER_NODE_TYPE

Could anyone help me ?
