UserWarning: LightFM was compiled without OpenMP support

Question

Please help! I'm trying to make a movie recommendation system.

I'm on windows using PyCharm.

I've tried installing lightfm on both PIP and Conda.

Any suggestions are welcome! I'm only a beginner.

Code:

import numpy as np
from lightfm.datasets import fetch_movielens
from lightfm import LightFM

# fetch data and format it
data = fetch_movielens(min_rating = 4.0)

# create model
model = LightFM(loss='warp')
# measures difference between model's prediction and desired output

# train model
model.fit(data['train'], epochs=30, num_threads=2)

def sample_recommendation(model,data,user_ids):

    #number of users and movies in training data
    n_users, n_items = data['train'].shape

    for user_id in user_ids:

        known_positives = data['item_labels'][data['train'].tocsr()[user_id].indices]

        scores = model.predict(user_id, np.arrange(n_items))

        top_items = data['item_labels'][np.argsort(-scores)]

        print("     Recommended:")

        for x in top_items[:3]:
            print("          %s"  % x)

# input 3 random user IDs
sample_recommendation(model,data,[3,25,450])

Output:
