没有名为NaiveBayes的模块

Question

我们正在实现的代码是

from NaiveBayes import  Pool
import os

DClasses = ["python",  "java",  "hadoop",  "django",  "datascience",  "php"]

base = "learn/"
p = Pool()
for i in DClasses:
    p.learn(base + i, i)



base = "test/"
for i in DClasses:
    dir = os.listdir(base + i)
    for file in dir:
        res = p.Probability(base + i + "/" + file)
        print(i + ": " + file + ": " + str(res))

但是我们得到了错误，就像找不到像奈维巴耶那样的模块。

---------------------------------------------------------------------------

      4 DClasses = ["python",  "java",  "hadoop",  "django",  "datascience",  "php"]
      5 

ModuleNotFoundError: No module named 'NaiveBayes'

帮助根除这种error.Thanks。

Answer 1

代码似乎不是来自学习朴素贝叶斯算法，在任何情况下，它都没有Pool属性或方法。

似乎您正在尝试使用另一个NaiveBayes库，在这种情况下，您的导入应该是

from NaiveBayes.Pool import Pool

如示例中所示。但是该消息意味着您尚未安装它；请从shell中尝试。

git clone https://github.com/yveskaufmann/Naive-Bayes

在您的当前目录中(也请参阅文档中的克隆Github repos)。
