Hi, I have been working through the Recommending movies: retrieval tutorial and in the Metrics portion of the jupyter notebook I have been receiving a ValueError: Cannot convert '('c', 'o', 'u', 'n', 't', 'e', 'r')' to a shape. Found invalid entry 'c' of type '<class 'str'>'. Here is the cell that is giving me problems: metrics = tfrs.metrics.FactorizedTopK(
candidates=movies.batch(128).map(movie_model),
)

import os
os.environ['TF_USE_LEGACY_KERAS'] = '1'

worked for me in google collab
