 Hi Dan, thanks for raising this. The python dependencies in colab change over time, which means that the environment that the code runs in may diverge from alphafold, even if the alphafold code itself is stable. We will update the requirements when this happens. The most recent commit updated jax and haiku to match the colab versions, so this issue should be fixed sorry, there is just a new error

 Hi this error is from a Phenix notebook that isn't maintained by DeepMind. Please raise this issue in the Phenix repo. Thanks!
This issue is reported by others earlier, but I rase this separately as a more permanent solution is needed. I've come to rely on Colab version of Alphafold but a couple of times recently it's been down for over a week without us having any idea when it would be fixed 

Would it be possible to make a second version available, that is known to be stable, so that if a new rollout fails there is something to fall back to? Or some other solution that could make it more reliable?

Thanks,
Dan
