RuntimeError: There were no tensor arguments to this function (e.g., you passed an empty list of Tensors), but no fallback function is registered for schema aten::_cat.
This usually means that this function requires a non-empty list of Tensors.
Available functions are [CPUTensorId, CUDATensorId, QuantizedCPUTensorId, VariableTensorId]
