Apparently it randomly becomes 0, inf, or nan. Also, zeroGradParameters doesn't seem to do anything.

require 'dpnn'
require 'cutorch'

local m = nn.Sequential()
m:add(nn.FireModule(1,1,1,1))
_, p = m:getParameters()
print(p:sum())

m = m:cuda()
_, p = m:getParameters()
print(p:sum())

m:zeroGradParameters()
print(p:sum())

Some outputs (randomly one of these)

-1.5261873854701e+236
nan
nan

1.117789947961e+138
inf
inf
