TensorFlow Developer certificate exam

How to train and save the model in google colab or GCP & AWS then import into pycharm.
I tried the pickle h5 model save method. is the h5 file enough for grading or do I need to buy Computing VM at GCP. I really don’t have GPU to train my model and can’t afford cloud GPU’s it’s expensive. please explain any other method.
Thank you for your time.

and to pass model around, don’t use pickle, try saving to a saved model (maybe compress it if necessary): Using the SavedModel format  |  TensorFlow Core
