PyCharm error No Module when trying to import own module python script

Question

I have written a module  a file my mod py file residing in the folder my module   Currently  I am working in the file cool script py that resides in the folder cur proj  I have opened the folder in PyCharm using File -- open  and I assume  hence  it is a PyCharm project    In ProjectView  CMD-7   I can see my project cur proj  in red  and under  External Libraries  I do see my module  In cool script py  I can write   from my module import my mod as mm   and PyCharm even makes suggestion for my mod  So far so good   However  when I try to run cool script py  PyCharm tells me   No module named my module   This seems strange to me  because  A  in the terminal  OS 10 10 2   in python  I can import the module no problem -- there is a corresponding entry in the PYTHONPATH in  bashrc  B  in PyCharm -- Settings -- Project cur proj -- Project Interpreter -- CogWheel next to python interpreter -- more -- show paths for selected interpreter icon  the paths from PYTHONPATH do appear  as I think they should   Hence  why do I get the error when I try to run cool script py   -- What am I missing   Notes    I am not declaring a different   special python version at the top of cool script py I made sure that the path to my module is correct I put   init   py files  empty files  both in my module and in cur proj I am not using virtualenv   Addendum 2015-Feb-25  When I go in PyCharm to Run -- Edit Configurations  for my current project  there are two options that are selected with a check mark   Add content roots to PYTHONPATH  and  Add source roots to PYTHONPATH   When I have both unchecked  I can load my module   So it works now -- but why    Further questions emerged    What are  content roots  and what are  source roots   And why does adding something to the PYTHONPATH make it somehow break  should I uncheck both of those options all the time  so also in the defaults  not only the project specific configurations  left panel of the Run Debug Configurations dialog

my module is a folder not a module and you can t import a folder  try moving my mod py to the same folder as the cool script py and then doimport my mod as mm  This is because python only looks in the current directory and sys path  and so wont find my mod py unless it s in the same directory  Or you can look here for an answer telling you how to import from other directories   As to your other questions  I do not know as I do not use PyCharm

This can be caused when Python interpreter can t find your code  You have to mention explicitly to Python to find your code in this location   To do so    Go to your python console Add sys path extend   your module location    to Python console    In your case    Go to your python console  On the start  write the following code   import sys sys path extend  my module URI location    Once you have written this statement you can run following command   from mymodule import functions

The answer that worked for me was indeed what OP mentions in his 2015 update  uncheck these two boxes in your Python run config     Add content roots to PYTHONPATH   Add source roots to PYTHONPATH    I already had the run config set to use the proper venv  so PyCharm doing additional work to add things to the path was not necessary  Instead it was causing errors

Pycharm 2017 1 1  Click on View- gt ToolBar  amp  View- gt Tool Buttons On the left pane Project would be visible  right click on it and press Autoscroll to source and then run your code   This worked for me

So if you go to   -  Setting -  Project My project -  Project Structure   Just the directory in which the source code is available and mark it as  Sources   You can see it on the same window   The directory with source code should turn blue  Now u can import in modules residing in same directory

The solution for this problem without having to Mark Directory as Source Root is to Edit Run Configurations and in Execution select the option  Redirect input from  and choose script you want to run  This works because it is then treated as if the script was run interactively in this directory  However Python will still mark the module name with an error  no module named x      When the interpreter executes the import statement  it searches for x py in a list of directories assembled from the following sources    The directory from which the input script was run or the current directory if the interpreter is being run interactively The list of directories contained in the PYTHONPATH environment variable  if it is set  An installation-dependent list of directories configured at the time Python is installed  in my case usr lib python3 6 on Ubuntu

Content roots are folders holding your project code while source roots are defined as same too  The only difference i came to understand was that the code in source roots is built before the code in the content root    Unchecking them wouldn t affect the runtime till the point you re not making separate modules in your package which are manually connected to Django  That means if any of your files do not hold the  from django import     or any of the function isn t called via django  unchecking these 2 options will result in a malfunction   Update - the problem only arises when using Virtual Environmanet  and only when controlling the project via the provided terminal  Cause the terminal still works via the default system pyhtonpath and not the virtual env  while the python django control panel works fine

If your own module is in the same path  you need mark the path as Sources Root  In the project explorer  right-click on the directory that you want import  Then select Mark Directory As and select Sources Root   I hope this helps

What I tried is to source the location where my files are   e g  E  git projects My project   init   py is my location   I went to File -  Setting -  Project My project -  Project Structure and added the content root to about mention place E  git projects My project  it worked for me

ln -s   someProject  If you have someDirectory someProjectDir and two files  file1 py and file2 py  and  file1 py tries to import with this line  from someProjectDir import file2  It won t work  even if you have designated the someProjectDir as a source directory  and even if it shows in preferences  project  project structure menu as a content root  The only way it will work is by linking the project as show above  unix command  works in mac  not sure of use or syntax for Windows   There seems some mechanism where Pycharm does this automatically either in checkout from version control or adding as context root  since the soft link was created by Pycharm in a dependent project  Hence  just copying the same  although the weird replication of directory is annoying and necessity is perplexing  Also in the dependency where auto created  it doesn t show as new directory under version control  Perhaps comparison of  idea files will reveal more

I was getting the error with  Add source roots to PYTHONPATH  as well  My problem was that I had two folders with the same name  like project subproject1 thing src and project subproject2 thing src and I had both of them marked as source root  When I renamed one of the  thing  folders to  thing1   any unique name   it worked   Maybe if PyCharm automatically adds selected source roots  it doesn t use the full path and hence mixes up folders with the same name

Always mark as source root the directory ABOVE the import  So if the structure is parent folder src module py you must put something like  from src module import function inside module and have parent folder marked as  quot source folder quot  in PyCharm

PyCharm Community Professional 2018 2 1  I was having this problem just now and I was able to solve it in sort of a similar way that  Beatriz Fonseca and  Julie pointed out    If you go to File -  Settings -  Project  YourProjectName -  Project Structure  you ll have a directory layout of the project you re currently working in  You ll have to go through your directories and label them as being either the Source directory for all your Source files  or as a Resource folder for files that are strictly for importing    You ll also want to make sure that you place   init   py files within your resource directories  or really anywhere that you want to import from  and it ll work perfectly fine    I hope this answer helps someone  and hopefully JetBrains will fix this annoying bug

The key confusing step that must be done is to recreate the run configuration for the source file that you re trying to execute  so that the IDE picks up the new paths    The way that actually worked for me was to go to Run Edit Configurations     select the configuration for the file that you re trying to run on the left side  uncheck the  Add source roots to PYTHONPATH  box  save  and then go back and check the box and save   THEN it would work
