首先你装个ironpython，然后就可以了啊。

给你几个例子程序。

Rating Prediction
#!/usr/bin/env ipy

import clr
clr.AddReference("MyMediaLite.dll")
from MyMediaLite import *

# load the data
train_data = IO.RatingData.Read("u1.base")
test_data = IO.RatingData.Read("u1.test")

# set up the recommender
recommender = RatingPrediction.UserItemBaseline() # don't forget ()
recommender.Ratings = train_data
recommender.Train()

# measure the accuracy on the test data set
print Eval.Ratings.Evaluate(recommender, test_data)

# make a prediction for a certain user and item
print recommender.Predict(1, 1) Item Prediction from Positive-Only Feedback#!/usr/bin/env ipy

import clr
clr.AddReference("MyMediaLite.dll")
from MyMediaLite import *

# load the data
train_data = IO.ItemData.Read("u1.base")
test_data = IO.ItemData.Read("u1.test")

# set up the recommender
recommender = ItemRecommendation.UserKNN() # don't forget ()
recommender.K = 20
recommender.Feedback = train_data
recommender.Train()

# measure the accuracy on the test data set
print Eval.Items.Evaluate(recommender, test_data, train_data)

# make a prediction for a certain user and item
print recommender.Predict(1, 1)

追问这两个程序貌似只能在ironPython3.0版本以上的实现~而ironPython官网版本只有2.7.5，能跑起来么？【Mymedialite库里头说跑不了，并且实践验证后也跑不了】，能请问你有python3.3.5版本或其他版本的Mymedialite应用例子么
