Got Similar error when using TF 1 ```tf.contrib.lookup.index_table_from_file(vocabulary_file="vocab_file.txt")```. Error was ```FailedPreconditionError: HashTable has different value for same key.``` The issue was input Vocab_file.txt had duplicate data. — sakeesh, Aug 26 '21 at 04:14

you cannot, unless you store the key's value as a list of values.

You cant do that, All the keys in the Hash map or Hash Table should be unique.

Else then you need to consider a different Collection
