I am using Python to do cosine similarity.

similarity_matrix = cosine_similarity(tfidf_matrix)

The problem is that I am getting this error

MemoryError: Unable to allocate 44.8 GiB for an array with shape (6011226750,) and data type float64

I don't think I need float64 for this operation as 2 digits after the decimal point should be enough.

Is there a way I can change the cosine_similarity data type to a smaller one?
