ModuleNotFoundError What does it mean main is not a package

Question

I am trying to run a module from the console  The structure of my directory is this     I am trying to run the module p 03 using bisection search py  from the problem set 02 directory using     python3 p 03 using bisection search py   The code inside p 03 using bisection search pyis     author      m    from  p 02 paying debt off in a year import compute balance after   def compute bounds balance  float                     annual interest rate  float  - gt   float  float          there is code here  but I have omitted it to save space     pass   def compute lowest payment balance  float                             annual interest rate  float  - gt  float         there is code here  but I have omitted it to save space     pass      def main        balance   eval input  Enter the initial balance          annual interest rate   eval input  Enter the annual interest rate           lowest payment   compute lowest payment balance  annual interest rate      print  Lowest Payment      str lowest payment     if   name         main         main     I am importing a function that is in p 02 paying debt off in a year py which code is     author      m    def compute balance balance  float                      fixed payment  float                      annual interest rate  float  - gt  float         this is code that has been omitted     pass   def compute balance after balance  float                            fixed payment  float                            annual interest rate  float                            months  int 12  - gt  float         Omitted code     pass   def compute fixed monthly payment balance  float                                    annual interest rate  float  - gt  float         omitted code     pass   def main        balance   eval input  Enter the initial balance          annual interest rate   eval          input  Enter the annual interest rate as a decimal          lowest payment   compute fixed monthly payment balance                                                     annual interest rate      print  Lowest Payment      str lowest payment     if   name         main         main     I am getting the following error   ModuleNotFoundError  No module named    main   p 02 paying debt off in a year      main    is not a package   I have no idea how to solve this issue  I have tried adding a   init   py file  but it is still not working

Remove the dot and import absolute import in the beginning of your file  from   future   import absolute import  from p 02 paying debt off in a year import compute balance after

User · Answer

Try to run it as   python3 -m p 03 using bisection search

User · Answer

Just use the name of the main folder which the  py file is in   from problem set 02 p 02 paying debt off in a year import compute balance after

User · Answer

Simply remove the dot for the relative import and do   from p 02 paying debt off in a year import compute balance after

I have the same issue as you did  I think the problem is that you used relative import in in-package import  There is no   init   py in your directory  So just import as Moses answered above  The core issue I think is when you import with a dot  from  p 02 paying debt off in a year import compute balance after  It is equivalent to  from   main   p 02 paying debt off in a year import compute balance after  where   main   refers to your current module p 03 using bisection search py   Briefly  the interpreter does not know your directory architecture  When the interpreter get in p 03 py  the script equals  from p 03 using bisection search p 02 paying debt off in a year import compute balance after  and p 03 using bisection search does not contain any modules or instances called p 02 paying debt off in a year   So I came up with a cleaner solution without changing python environment valuables  after looking up how requests do in relative import   The main architecture of the directory is  main py setup py problem set 02       init   py    p01 py    p02 py    p03 py  Then write in   init   py  from  p 02 paying debt off in a year import compute balance after  Here   main   is   init     it exactly refers to the module problem set 02  Then go to main py  import problem set 02 You can also write a setup py to add specific module to the environment

If you have created directory and sub-directory  follow the steps below and please keep in mind all directory must have    init   py to get it recognized as a directory   In your script  include import sys and sys path  you will be able to see all the paths available to Python  You must be able to see your current working directory   Now import sub-directory and respective module that you want to use using  import subdir subdir modulename as abc and now you can use the methods in that module     As an example  you can see in this screenshot I have one parent directory and two sub-directories  and under second sub-directories I have the module CommonFunction  On the right my console shows that after execution of sys path  I can see my working directory
