I am attempting to build a model to predict whether a product will get sold on an ecommerce website with 1 or 0 being the output.

My data is a handful of categorical variables, one with a large amount of levels, a couple binary, and one continuous (the price), with an output variable of 1 or 0, whether or not the product listing got sold.

This is my code:

inTrainingset<-createDataPartition(C$Sale, p=.75, list=FALSE)
CTrain<-C[inTrainingset,]
CTest<-C[-inTrainingset,]


gbmfit<-gbm(Sale~., data=C,distribution="bernoulli",n.trees=5,interaction.depth=7,shrinkage=      .01,)
plot(gbmfit)


gbmTune<-train(Sale~.,data=CTrain, method="gbm") …

我使用python 2.7.8 64位.我正在尝试使用numpy包导入CSV文件.我一直得到***关键字不能表达,然后它给我路径并说第6行,所以我假设第6行是问题所在.

这是我的代码.

import numpy as np

def main():

    try:
        date, rate, arb = np.loadtext('TutSheet.csv'.
                                    delimter=',',
                                    unpack=True,
                                    dtype='str')

        print date

    except Exception, e:
            print str(e)
