Why is temp_blob_ necessary?

[nicklhy]

I noticed that the current shuffle operation use temp_blob_ as the intermediate variable for memory copy. Why can't we just set top_data as the "output" argument of Resize_gpu?

This is the first version. You can do that

when i running there is always has problem as follows:
[math_functions.cpp:91] Check failed: error == cudaSuccess (11 vs. 0) invalid argument.

I think this is caused by caffe_copy(). Could you help me solve this problem?
