Colab demo limit

[dkokron]

Is there a limit on the number of times someone can run the gencast_demo_cloud_vm.ipynb demo on the Colab using the TPU2 hardware? I ran it yesterday as far as plotting the ensemble outputs. Now I want to run the training part of the demo, but it won't let me past the part where it asks for paths to model data.
