Inf while testing with steepness_train.c

[sangeeta0201]

Hello,

I have been trying to learn how to use fann for my project. I tried steepness_train example from the examples directory. For this example, I used -ldoublefann. For every epoch, I am getting the same "Current error: 0.2500000000". While investigating further it turns out that max_sum in src/fann.c:790 is giving inf and the reason seems to be that steepness is not initialized.
Can please somebody tell me how this issue can be fixed?
To reproduce this bug, you can modify Makefile in the examples folder to link with -ldoublefann, run steepness_train, and check for max_sum value.
