Availability of Pretrained EfficientNets Checkpoints

[xhluca]

With the release of EfficientNet, it is interesting great to see the partial release of checkpoints:

We have provided a list of EfficientNet checkpoints for EfficientNet-B0, EfficientNet-B1, EfficientNet-B2, and EfficientNet-B3.

Is there any reason why the weights for B4 to B7 are not released yet? Is there plans to release them in the future?

Thanks!

Can you also provide the checkpoints at the couple first epochs during training b0-b3. We would like to try to apply Lottery Ticket Hypothesis on EfficientNet b0-b3. Many thanks

I have released B4 and B5:

https://storage.googleapis.com/cloud-tpu-checkpoints/efficientnet/efficientnet-b4.tar.gz (ImageNet top1 acc=82.6%)
https://storage.googleapis.com/cloud-tpu-checkpoints/efficientnet/efficientnet-b5.tar.gz (ImageNet top1 acc=83.2%)

We will release B6 and B7 in future.

Thank you!!!!

Anyone has weights for the B7 version?

[HarshitSheoran]

@digital-thinking Not yet available, I am also waiting.

The B6 and B7 checkpoints are available: https://github.com/tensorflow/tpu/tree/master/models/official/efficientnet
Do you know if you intend to convert them to weights and make them available?
Thank you very much!

Can someone clarify how to use these checkpoints to fine tune to a custom dataset?
I tried to put them on the output model_dir so they can resume from there, but keep stumbling into missing or changed operations? See #652
