unable to load model -Unknown initializer: EfficientConv2DKernelInitializer

[emoen]

I try to load a model I created about in june 2019, but it doesnt load. I suspect it has something to do with the refactoring done on efficientnet.

When creating the model i used: from efficientnet import EfficientNetB4

while in later work I have used: import efficientnet.keras as efn

so I guess there has been a refactoring inbetween. How do I load the old model?

The error message Im getting is:

Try installing an older version of the package, like ver. 0.0.2. You can install it with pip install efficientnet==0.0.2. Here's full version history https://pypi.org/project/efficientnet/1.1.1/#history
