ImportError: No module named 'ExceptionNotSeen'

[Yuhao Zhang]

Maybe something is missing...

Traceback (most recent call last):
File "/Users/ZhangYuhao/Documents/Datamining/project/Q_number.py", line 3, in
from naiveBayesClassifier.trainer import Trainer
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/naiveBayesClassifier/trainer.py", line 1, in

from ExceptionNotSeen import NotSeen
ImportError: No module named 'ExceptionNotSeen'

Could anyone help me out?

[Prateek Mahendrakar]

seems there is something wrong with the install import or python path in system variable.

Solve it this way

1. Go to this folder /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/naiveBayesClassifier
2. Copy ExceptionNotSeen.py to your current project path(where you run your main python program

It solved that issue for me.

Thks!

Does not work in virtual environment (anaconda)
Still getting thrown the same error
Naive Bayes Classifier has the ExceptionNotFound in its folder
Tried storing the file locally in the project directory but it's not working

[Prateek Mahendrakar]

you need to import class NotSeen into all dependent class files.
Add from ExceptionNotSeen import NotSeen in all relevent files under C:\Users\Username\AppData\Local\Programs\Python\Python36\Lib\site-packages\naiveBayesClassifier

I did that to

• classifier.py
• trainedData.py

It should solve your issue

[Elias Kelly]

All files already make this import

whats the error message you are getting ? post it here

I am getting the following error with Anaconda:

Not sure about anaconda or virtual environment.

I would cross check for ExceptionNotSeen.py file in C:\Users\username\AppData\Local\Continuum\Anaconda3\lib\site-packages\naiveBayesClassifier directory.

Also check whether ExceptionNotSeen.py has been define as below

class NotSeen(Exception):
    """
    Exception for tokens which are not indexed 
    because never seen in the trainin data
    """
    def __init__(self, value):
        self.value = value
    
    def __str__(self):
        return "Token '{}' is never seen in the training set.".format(self.value)

And

Add from ExceptionNotSeen import NotSeen in all relevent files classifier.py , trainedData.py in same directory too.

i got the same error.

Is the version of python that many of you are using is 3.x? If so, download 2to3, copy 2to3 file to dir of genderizer package, then open the terminal in genderizer package dir and run the following command:

2to3 -w .

which converts all the python files to the version 3. This should solve all the above problems and this has worked for me!

the same error。。。。

[YiTingYan]

seems there is something wrong with the install import or python path in system variable.

Solve it this way

It solved that issue for me.

I don't have this file(.py)

[Karmel Salah]

You can try this "
from naiveBayesClassifier.ExceptionNotSeen import NotSeen " it worked for me in all required files
