   Many intermediate tensors are recorded which may affect the performance of automatic memory
recycling. The scheduler won't recycle the tensor used on the Python side.
   [example in autograd.py](https://github.com/apache/singa/blob/dev/python/singa/autograd.py#L2013)
   x, mean and var is recorded on the Python side and they always exist after every iteration,
so the scheduler won't recycle them, but they could have been recycled.
