代码如下：

`while line:
       `fids = line[0]`
       `fids = [[f] for f in fids]`
 `       lods = line[1]`
 `       labels = line[2]`
 `       print fids`
 `       print lods`
 `       print labels`
 `       feas = fluid.LoDTensor()`
 `       feas.set(fids, fluid.CPUPlace())`
 `       feas.set_lod(lods)`
 `       line = test_reader.next()`

报错信息如下：
[[1], [3], [5], [7], [9], [2], [4], [6], [8], [10], [1], [2], [3], [4]]
[[5, 5, 4]]
[1, 0, 0]
