Mmdetection: EfficientNet backbone

[dhananjaisharma10]

Hi!

I am trying to write a new backbone. Can someone please guide me through the process? I am particularly interested in knowing how to link the feature maps of the backbone with FPN.

Thanks!

It can be something like this implementation (not finished but working)

@JegernOUTT Thanks for the reference. I am currently trying to figure out an alternate way to get the same padding feature as in TF to remove the need for a separate wrapper class for Conv2d.
