AttributeError: module 'keras_tuner.engine' has no attribute 'tuner'

Question

I am using google colab and i have been trying to import autokeras, however when i do so, I get this error below. I have tried !pip install autokeras. I have tried to updated tensorflow, autokeras, keras, and keras-tuner to fix it but this does not help. I am unsure how to solve this issue.

import autokeras as ak

As keras_tuner was updated (https://github.com/keras-team/keras-tuner/blob/master/keras_tuner/engine/tuner.py line 35), you must edit your file /usr/local/lib/python3.10/dist-packages/autokeras/engine/tuner.py line 30 :

class AutoTuner(keras_tuner.Tuner):

Or simply :

pip install keras-tuner==1.3

pip install typing-extensions --upgrade
