Traditionally the idiom
next(iter(loader))has been used in examples to take a peek at the first batch, but due to changes in Tensorflow >= 2.10,next(iter(loader))might show unpredictable behavior, especially with list columns. Dataloader now has apeek()method, which is more robust. This PR replacesnext(iter(loader))in the movie lens notebooks with thepeek()method.Testing
