I want to view my downloaded data in tensor flow

Ratings data.

ratings = tfds.load(‘movielens/100k-ratings’, split=“train”)

Features of all the available movies.

movies = tfds.load(‘movielens/100k-movies’, split=“train”)

Select the basic features.

ratings = ratings.map(lambda x: {
“movie_title”: x[“movie_title”],
“user_id”: x[“user_id”]
})
movies = movies.map(lambda x: x[“movie_title”])

Hi @Priyank_Dubey, You can view the data present in the ratings dataset using

for data in ratings.take(5):
  print(data)

The output looks like

To view the specific column data you have to pass the column name,

for data in ratings.take(5):
  print(data['movie_title'])
#output
tf.Tensor(b"One Flew Over the Cuckoo's Nest (1975)", shape=(), dtype=string)
tf.Tensor(b'Strictly Ballroom (1992)', shape=(), dtype=string)
tf.Tensor(b'Very Brady Sequel, A (1996)', shape=(), dtype=string)
tf.Tensor(b'Pulp Fiction (1994)', shape=(), dtype=string)
tf.Tensor(b'Scream 2 (1997)', shape=(), dtype=string)

To get the exact values you can use .numpy method

for data in ratings.take(5):
  print(data['movie_title'].numpy())
#output
b"One Flew Over the Cuckoo's Nest (1975)"
b'Strictly Ballroom (1992)'
b'Very Brady Sequel, A (1996)'
b'Pulp Fiction (1994)'
b'Scream 2 (1997)'

Thank You.
