result not reproduced by taking gradient wrt logit and flipping sign

I had the same doubt as #83 #107 #41
I flipped the sign for tcav calc (< changed to >)and took gradient wrt logit(unnormalized output of network, self.pred).

So the output for importance of zebra in inception network when wrt loss and < sign

whereas when wrt output and > sign I get this
