The error message you are encountering, “TypeError: ‘word2vec’ object is not subscriptable,” suggests that you are trying to access elements of an object that doesn’t support that operation. The term “subscriptable” refers to the ability to access elements using square brackets ([]).
One possible reason for this error is that you are trying to access elements of an object of the type ‘word2vec’ as if it were a list or a dictionary. However, the ‘word2vec’ object does not support subscripting, which means you cannot use square brackets to access its elements.
To understand this better, let’s consider an example. Suppose you have a ‘word2vec’ object named ‘model’ which is trained on a large text corpus. You might want to retrieve the vector representation of a particular word, such as “apple.”
var model = Word2Vec.load("path/to/word2vec_model");
// Incorrect usage, which leads to the error
var vector = model["apple"];
In the above example, attempting to access the word vector with square brackets would result in the “TypeError: ‘word2vec’ object is not subscriptable” error because the ‘word2vec’ object does not support subscripting.The correct way to retrieve the word vector from a ‘word2vec’ model is by using the model.wv attribute, which stands for word vectors.
var model = Word2Vec.load("path/to/word2vec_model");
// Correct usage, accessing word vectors using 'wv' attribute
var vector = model.wv.getVector("apple");
In the corrected example, we access the word vector by using the getVector method of the wv attribute on the ‘word2vec’ model object. This retrieves the desired word vector without raising any errors.
So, make sure you are using the correct syntax to access elements of your ‘word2vec’ object, and avoid trying to subscript it like a list or dictionary.
