In PyCharm, I've added the Python environment /usr/bin/python. However,
from gnuradio import gr
fails as an undefined reference. However, it works fine in the Python interpreter from the command line.
GNURadio works fine with python outside of Pycharm. Everything is installed and configured how I want it.
Gnuradio is located at /usr/local/lib/python2.7/site-packages/gnuradio
Also:
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/gnuradio
Adding a Path
Go into File → Settings → Project Settings → Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
But I don't know the path..
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.
You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
For me, it was just a matter of marking the directory as a source root.
Add path in PyCharm 2017

You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.
DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root
In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')
On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.
I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.
In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package
For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.

I have created a virtualenv using command prompt and have installed all my dependencies. How can I make PyCharm use the virtual env & dependencies created via command prompt?
You should link the virtualenv in PyCharm.
In order to do this, go to:
File -> Settings -> Project -> Project Interpreter
Here, in the top right corner of the window, click on the gear icon and choose Add.
Then, choose Existing environment option and navigate in your computer until you find the python.exe for your virtualenv.
Than confirm modifications clicking Ok. This should be enough.
If you want to use it in a PyCharm configuration, please do not forget to choose it in the Python Interpreter option.

Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
For me, it was just a matter of marking the directory as a source root.
Add path in PyCharm 2017
File -> Settings (or Ctrl+Alt+S) -> Project -> Project Interpreter
Show all
Select bottom icon on the right side
Click on the plus button to add new path to your module
My version is PyCharm Professional edition 3.4, and the Adding a Path part is different.
You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.
DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root
In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')
On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.
I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.
In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package
For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.
Download anaconda

once done installing anaconda...
Go into Settings -> Project Settings -> Project Interpreter.
Then navigate to the "Paths" tab and search for /anaconda/bin/python
