TF1 c2 w1 Assignment is taking way to long to train

My model is 3 conv
then flatten
dense 512
dense 1
optimaizer is Adam
but it takes about 10 min for 1 epoch
total is about 2:15 hours
did i do something wrong or it just take this much to train

Are you using a GPU?

only the first time, then the site prevented me from using GPU runtime
even the first time took so long, over an hour

Please upgrade to colab pro for 9.99 $ / month. With GPU, model training usually takes few seconds per epoch.

I am using the default configuration of colab. It is running pretty fast for me and completed the notebook tasks

Money pay the time makes sense!
