the use of another dataset

[ZouhairBALLOUCH]

Hello Sir,
Please I tried to apply the Segnet-Pytorch code you developed using the SEMCITY TOULOUSE dataset
(http://rs.ipb.uni-bonn.de/data/semcity-toulouse/)

I want to inform you that I have changed only the classes at the code level.
Please find below the results I obtained:
impervious surface = nan
building = 0.99
pervious surface = nan
high vegetation = nan
car = nan
water = nan
sport venues = nan

Please I would like to know why the nan in the all classes except the Building class
Thank you for your help
