Python error ' ModuleNotFoundError:'

Question

I am getting this error

Traceback (most recent call last):
File "Exporter.py", line 3, in <module>
import sys,getopt,got,datetime,codecs
File "C:\Users\Rohil\Desktop\GetOldTweets-python-master\got\__init__.py", line 1, in <module>
import models
ModuleNotFoundError: No module named 'models'

my directory tree is:

C:\Users\Rohil\Desktop\GetOldTweets-python-master\got

this contains 2 folders: manager and models and 1 __init__.py file with the code :

import models
import manager

i am executing a file with the path: C:\Users\Rohil\Desktop\GetOldTweets-python-master\Exporter.py

I can't figure out what the issue is. can anyone assist me?

Answer 1

If you have created a directory and sub-directory then follow the below steps and please keep in mind that a directory must have an __init__.py file for python to recognize it as a package.

1. First run this to see all paths being searched by python:

import sys
sys.path

You must be able to see your current working directory in that list.

2. Now import the sub-directory and the respective module that you want to use via the import command: import subdir.subdir.modulename as abc You should now be able to use the methods in that module.

enter image description here

As you can see in this screenshot above I have one parent directory and two sub-directories. Under the second sub-directory I have a module named CommonFunction. On the console to the right you can see my working directory after execution of sys.path.

• Hlung: what if one of the path has a dot?

Answer 2

Set the environment variable PYTHONPATH=C:\Users\Rohil\Desktop\GetOldTweets-python-master\got (how exactly, depends on your operating system)

• blue note: can you import the other module? also, make sure that your terminal sees the correct PYTHONPATH value
• Rohil: created a new variable in windows called 'PythonPath' and added C:\Users\Rohil\Desktop\GetOldTweets-python-master\got as the value. Still throws the same error
• Rohil: nope, cant import any module from that folder. How do i make sure that the terminal sees the correct pythonpath value on windows?
• blue note: the variable should be IN CAPITAL letters. then, at command prompt, try echo %PYTHONPATH% and check that you see the correct value
• blue note: Well, it worked so far, now you have a different problem than before, need more info. Also, make use that your init.py is empty file (does not import anything)

Answer 3

• Does the models folder has an __init__.py file inside it ? Only then, it will be recognized as a module by python and import models would make sense.

So,

• Create an empty __init__.py file in the models subfolder and then the code should work without any issues.

You should also look at this answer.

• Rohil: my models folder too has a _init_.py file. Still gives the error
• Rohil: my models folder has a _init_.py file which contains: from Tweet import Tweet

Answer 4

If you are using python3 but are installing the API through 'pip install 'such and such'. It's not gonna work on python3 console. Therefore, you'd better use 'sudo python3 -m pip install 'such and such''. Then it's gonna work! (at least for ubuntu stuff)

:)

• Anton Samokat: Thanks. Adding sudo to python3 -m pip install "module_name" helped to me.

Answer 5

if create d or using or custom python package

check our dir. correct.

** For python 3.7 user **

from. import module_name
