Word To Vec with Spacy, words into same categorie
If you need word-vectors for words not in the model you're using, you'll have to either:

find & use a different model that contains those words
train your own model from your own training data, that contains many examples of those words' usages in context
i try do cluster words into the same category. Therfore i wanted to use Spacy Word2Vec.
Its already working with easy words like banana apple and car. It shows the nearly same word.
If the words gets more specific like car, battery, accumulator, accu and so on, if the were more technical, Spacy sends Zero vectos. So these words were not included into the bibliothek. 
Do you have some input for me?
Furthermore, i have to do it in german. 
Thank you very much
