"Neural Networks NaN Error"

Hello,

I am try to train my Neural Network on the data set at http://sites.google.com/site/motazsite/teaching/data-mining-discussion/trndataCSV.csv

But I got the error below.

Process failed: operator cannot be executed (Trying to assign invalud number to matrix: NaN)

I trained many NN without any problem. What is wrong with this dataset?


Thanks,
Motaz
