Beginner nit: please advise GPU runtime is required in the Colab (or grab it as part of page code)

[ejrejr]

I have the book and started with the Google Colab. Repro I hit:

• Go to first Colab page (01_intro.ipynb)
• Start executing the code blocks
• For the first training, execute and note first dog / cat training sequence takes like 27 minutes. Then a subsequent training estimates 51 minutes.
• Interrupt and reload the page to start over.
• Explicitly change runtime to GPU.
• Re run first dog / cat training and see it takes less than 3 minutes total. I <3 GPUs.

Please either add instructions to the top of the pages to instruct changing runtime type or have code in the page setup the appropriate runtime. This is probably the first time many people are using Colab / GPUs / training and they need all the help they can get.

Thanks.

How long are the training sessions supposed to take one of them was taking over 2 hrs in the first lesson using the standard gpu from colab
