make runtest fail

[AliRaza21918]

OS:: Ubuntu16.04 CPU_ONLY

I have make changes in the line 56 of "contrastive_loss_layer.cpp" file to fix an error while make all Dtype dist = std::max(margin - (float)sqrt(distsq.cpu_data()[i]), Dtype(0.0)); here “(float)” is added

So when I executed make runtest my terminal display this result

Somebody plz help me

[AliRaza21918]

@alexgkendall plz help me to solve this problem

[vinicius-cleves]

I solved this by changing the line 168 in test_gradient_check_util.hpp to (float)(std::max(fabs(computed_gradient), fabs(estimated_gradient))), (float)1.);

[Villjoie]

I solved this by changing the Dtype scale = std::max( std::max(fabs(computed_gradient), fabs(estimated_gradient)), 1.);

to Dtype scale = std::max( std::max(fabs(computed_gradient), fabs(estimated_gradient)), Dtype(1.));
