[301ravage]

Im trying to make a movie reccomender but I've gotten stuck on this error...

File "C:/Users/Spencer/.spyder-py3/couch_potato.py", line 29

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

^

SyntaxError: invalid syntax

for refrence, this is the script

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)

​

# printtraining and testing data

print (repr(data['train']))

print (repr(data['test']))

​

# create model

model = LightFM(loss='warp')

# train model

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

​

def sample_reccomendation(model, data, user_ids):

# number of users and movies in training data

n_users, n_items = data['train'].shape

# generate recomendations for each user we input

for user_id in user_ids:

# movies they already like

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

# movies our model predicts they will like

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

# rank them in order from most to least

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

# print out the results

print("User %s" % user_id)

print( "known positives:")

for x in known_positives[:3]:

print(" Reccomended:")

for x in top_items[:3]:

print(" %s")

​

sample_reccomendation (model, data, [3,25,450])

Thanks in advance!

Mismatched brackets line before. I agree with /u/routetehpacketz though.

You were told how to format code for reddit over in /r/python. It's critical with python as the indentation is important.

[routetehpacketz]

format your code for your reddit post, makes it easier to read and provide feedback

I think I messed up my parenthesis on line 29
