Yet-another-efficientdet-pytorch: training time really long

Hi there, excellent work and thanks for sharing it!

I tried the recommended script, 3.a. Train on coco from scratch with default setting. It will take about 20 days. Did you train all theses models from scratch or from imagenet pre-trained models?

Thanks a lot!

Finetuned from tensorflow efficientdet model?

yes

Then why finetune is necessary? Shouldn鈥檛 the test result same as tensorflow Efficient det report?

the low level implement of TF and pytorch is slightly different. So the output of pytorch's is about 1e-3 deviating from the official one, hence the finetune

@LiangTinting I'm curious about Finetuned from tensorflow efficientdet model. What's the meaning of this?load tensorflow model?How to do it?
