AttributeError: 'AvgPool3d' object has no attribute '__flops__'

Thanks for your error report and we appreciate it a lot. If you feel we have help you, give us a STAR! 😆

Checklist

1. I have searched related issues but cannot get the expected help.
2. The bug has not been fixed in the latest version.

Describe the bug

I was trying to get the FLOPs of the tpn_imagenet_pretrained_slowonly_r50_8x8x1_150e_kinetics_rgb model but I encountered this AttributeError. And it seems like the AvgPool3d module wasn’t properly added the __flops__ attribute.

Reproduction

1. What command or script did you run?

python tools/analysis/get_flops.py configs/recognition/tpn/tpn_imagenet_pretrained_slowonly_r50_8x8x1_150e_kinetics_rgb.py --shape 1 3 8 340 256

1. Did you make any modifications on the code or config? Did you understand what you have modified?

No

1. What dataset did you use?

Kinetics-400. But it doesn’t matter here.

This code was written by another colleague one year ago. Give me sometime to figure out the logic.
