Not able to reproduce the same results on Resnet as reported in the paper #1

Hi, the acc of trained ann resnet is 0.80 , but when I try to convert it into snn using this code , the converted snn acc is only 0.77. In the fuse_norm_replace function of the snn which reaches 0.77 on acc , I only norm the bn1 and bn2 in a resnet block, while I didn't norm the bn layer which is used to down_sample the identity. For the bn1, I used the max_act of the current bn layer and the add layer of the last resnet block (the add layer is added specially to obtain the max_act). Then I tried to norm the down_sample bn also (different tries, include using the max_act of current bn and the add layer in last block ), the acc has dropped a lot. By the way, the result on VGG16 is reproduced acceptable, thank you for providing the code! expecting your reply, thank you in advance!

hi, which kind of resnet did you use? resnet34 or resnet 18? and at what timesteps your snn reaches 0.77?
