File not found Error in Naïve Bayes Project

[handyworkz]

This is the code

import sys
from time import time
sys.path.append("C:/Users/ADWIN/Documents/GitHub/ud120-projects/tools")
from email_preprocess import preprocess

features_train, features_test, labels_train, labels_test = preprocess()

from sklearn.naive_bayes import GaussianNB
clf = GaussianNB()
t0 =time()
clf.fit(features_train, labels_train)
print ("Training time: ", round(time()-t0, 3), "s")

t1 =time()
predictions = clf.predict(features_test)
print ("Prediction time: ", round(time()-t1, 3), "s")

from sklearn.metrics import accuracy_score
accuracy = accuracy_score(labels_test, predictions)
print(accuracy)

And this, the error

c:/Users/ADWIN/Documents/GitHub/ud120-projects/naive_bayes/nb_author_id.py Traceback (most recent call last): File "c:\Users\ADWIN\Documents\GitHub\ud120-projects\naive_bayes\nb_author_id.py", line 22, in <module> features_train, features_test, labels_train, labels_test = preprocess() File "C:\Users/ADWIN/Documents/GitHub/ud120-projects/tools\email_preprocess.py", line 30, in preprocess authors_file_handler = open(authors_file, "rb") FileNotFoundError: [Errno 2] No such file or directory: '../tools/email_authors.pkl'

Anytime I try to run the code, this error pops up, I have tried moving the email_preprocess file into the naive_bayes directory but the issue persists.

Can any one help?

You can see this code

from sklearn.naive_bayes import GaussianNB

""" this is the code to accompany the Lesson 1 (Naive Bayes) mini-project use a Naive Bayes Classifier to identify emails by their authors authors and labels: Sara has label 0 Chris has label 1 """ import sysfrom time import timesys.path.append("../tools/")from email_preprocess import preprocess

For me the problem was that I executed the code in an IDE. Even though I ran nb_author_id.py, the working directory was the root directory of the repository.

For me it worked by first doing

import os
os.chdir("naive_bayes")
