Bottleneck doubt

[elun15]

Hello, Why do you call Bottleneck to the Batch Normalization layer in the following line?

https://github.com/didi/mtmc-vt/blob/f7379e0bb37edff0ece1366d6dd4089fe7090839/src/reid_baseline/modeling/baseline.py#L46

I suppose it has nothing to do with Resnet Bottleneck block, isn't it?

Thank you!
