Hi, to use another backbone.
resnext.py
under directory tri_loss/model
. The content is the original resnext.py
provided by pytorch.forward
function of resnext
, removing unnecessary operation after this line x = self.layer4(x)
, so that it returns the result of layer4
.from .resnext import resnext50
in tri_loss/model/Model.py
, and then replace this line
self.base = resnet50(pretrained=True, last_conv_stride=last_conv_stride)
with
self.base = resnext50(pretrained=True)
If you would like to reduce the last convolutional stride of the backbone, you can modify it yourself in resnext.py
accordingly.
Thank you very much for your clear explanation.
I want to check with different networks like Efficient net, Inception. Where do I get pretrained weight for these networks.
Can you suggest which pretrained network is preferred for reidentification. Thank you.

Can I get anystrong literature to choose best pre-trained model for people reidentification. Kindly suggest Thank you.

Sorry for the late response. If you want to try on many different backbones or understand which one is better, as well as some training tricks, you can read the paper FastReID: A Pytorch Toolbox for General Instance Re-identification and the accompanying code https://github.com/JDAI-CV/fast-reid.
How to train with different pre-trained models. please reply.
