Pre-trained FastText model not loading - Error "NameError: name 'BaseKeyedVectors' is not defined"

[alessandra stampi-bombelli]

Hello,

I trained some word vectors and have not been able to load them again, to access the dictionary and perform other operations. 

I get the error:

  File "~/lib/python3.7/site-packages/gensim/models/keyedvectors.py", line 224, in load
    Parameters

 "NameError: name 'BaseKeyedVectors' is not defined"

Here are the modules I have installed:

import matplotlib
matplotlib.use('Agg')
import numpy as np
from scipy.spatial.distance import cosine
from nltk.stem.snowball import SnowballStemmer
stemmer = SnowballStemmer("english")
import matplotlib.pyplot as plt
from wordcloud import WordCloud
import os
import joblib
from gensim.models import Word2Vec
import random
from gensim.models import KeyedVectors
import pandas as pd
from sklearn.metrics.pairwise import cosine_similarity
import sys

And here is how I am trying to load it:

model = KeyedVectors.load('fasttext_1860-1920_100k_preprocessed.kv', mmap='r')

I have done this in the past with another model and it worked. Can someone please help me out with this?

Thank you and best regards,

Sandra
