The error message “‘word2vec’ object is not subscriptable” typically occurs when you try to access or index a value within an object of the word2vec class, but the object does not support subscripting or indexing.
To better understand this error, let’s consider an example. Suppose you have imported the word2vec model from the gensim library in Python and loaded a pre-trained word2vec model into an object named “model”.
import gensim.models
# Load pre-trained word2vec model
model = gensim.models.Word2Vec.load("model.bin")
Now, if you mistakenly try to subscript or index the “model” object directly, such as using square brackets [], you will encounter the mentioned error. This is because the “model” object does not support direct subscripting or indexing.
# Incorrect usage - subscripting on 'model' object
vector = model['example']
# This will result in the error: "'word2vec' object is not subscriptable"
To access the word vector for a specific word using word2vec, you need to use the built-in functions provided by the model object. For instance, you can try the following:
# Correct usage - accessing word vector using built-in function
vector = model.wv['example']
In the corrected example, the “model.wv[‘example’]” statement retrieves the word vector representation for the word “example” from the word2vec model. The “wv” attribute allows access to the word vectors, and the square brackets are used to retrieve the vector for a specific word.
