A new problem occurred while I was running the Alphafold
I think this was caused by the changes in v2.3.0 which happened recently - your Colab notebook likely got out of sync with the code. Could you try running in a fresh notebook?
 https://colab.research.google.com/github/deepmind/alphafold/blob/main/notebooks/AlphaFold.ipynb
When I entered the amino acid sequence, the program reported an error：

AttributeError                            Traceback (most recent call last)

     27     min_length=MIN_SINGLE_SEQUENCE_LENGTH,

AttributeError: module 'alphafold.notebooks.notebook_utils' has no attribute 'validate_input'
I don't know what's going on, I hope everyone can help me.
