title: ModuleNotFoundError: no module named efficientnet.tfkeras
body: <p>I attempted to do <code>import segmentation_models as sm</code>, but I got an error saying <code>efficientnet</code> was not found. So I then did <code>pip install efficientnet</code> and tried it again. I now get <code>ModuleNotFoundError: no module named efficientnet.tfkeras</code>, even though Keras is installed as I'm able to do <code>from keras.models import *</code> or anything else with Keras</p>
  
  <p>how can I get rid of this error?</p>
