makeTensorFromTensorInfo(tensorInfo, backend) {
        const { dataId, shape, dtype } = tensorInfo;
        const t = new (0, _tensor.Tensor)(shape, dtype, dataId, this.nextTensorId());

    }
Internal method used by backends. Makes a new tensor that is a wrapper
around an existing data id in TensorInfo. It doesn't create a new data id,
only increments the ref count used in memory tracking.
