Check failed when make runtest

[xmfbit]

When run make runtest after building FlowNet2, check failure error occurs in custom_data_layer:

I am using Ubuntu16.04.2, GCC version 5.4.0, CUDA8.0 with CUDNN6.0, with Intel MKL.

I got the same error when making runtest, but it runs well when tranining.

Hi,
the custom_data_layer is one of our own layers, right? We didn't include proper testing, so I'm not surprised that make runtest fails. As @thbupt comments, it should still run fine.

Best,
Nikolaus
