Problems running the ungraded notebooks for weeks 1 and 2

Hi guys,
I’m having problems running the following ungraded notebooks:

  1. week 1’s keras tuner (first lab of week 1)
  2. week 2’s quantization notebook (last lab of week 1)

for the keras tuner notebook, the issue comes from the model_builder function which uses the same name fpr the fc layer dense_1 which generates the error that each layer in the network should have a unique name.

for the week 2’s notebook, it was just a strange error.

I encountered these errors running on colab without any modifications. anyone faced similar thing?

I noticed you can just re-run the cell and it works fine then

If you give that layer a different name after running it would be added to the network, not replacing that layer isn’t it?
