没有名为 NaiveBayes 的模块

Question

我们正在实施的代码是

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))

但是我们遇到了错误，比如没有找到像 naivebayes 这样的模块。

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-21-30788f518a4c> in <module>()
----> 1 from NaiveBayes import  Pool
      2 import os
      3 
      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 scikit-learn Naive Bayes algorithms，无论如何，它没有 Pool 属性或方法。

您似乎正在尝试使用 another NaiveBayes library，在这种情况下，您的导入应该是

from NaiveBayes.Pool import Pool

如图example那里。但是该消息暗示您尚未安装它；从 shell

尝试

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

在您的当前目录中（另请参阅 documentation 用于克隆 Github 存储库）。
