I have an package thats imported from the parent path everywhere. So i have to set PYTHONPATH enviromentvariable when i want to serve the docs for that package.
Ive searched the Docs,stack overflow, google but couldn't find an solution to configure that in the mkdocs.yml or run an piece of python code to append it to sys.path
Edit:
handlers:
python:
setup_commands:
- import sys;sys.path.append('..');print(sys.path)
could be what i search for, but during mkdocs build (or serve) the print is never called
The solution is really to use the setup_commands. Prints don't seems to be showed there and my problem was that an used package wasn't installed. The error message then is the same as when the import isn't be found.

I'm on day 1 of Python and trying to import SciPy into a project. I installed it via pip install on ElementaryOS (an Ubuntu derivative). I have verified it's existence via:
$ python
>>> help("modules")
The exact error I'm getting is:
Import "scipy" could not be resolved Pylance (reportMissingImports)
When searching for this error I found:
Import could not be resolved/could not be resolved from source Pylance in VS Code using Python 3.9.2 on Windows 10 Powershell -- the accepted answers all pointed towards a project specific .env file. I have no such project structure, nor does it make sense to me that one would be needed.
A github issue -- this issue ends with "it just fixed itself"
When I run my program, I get no errors in console. And looking up "Pylance" it appears to be a Microsoft product. I suspect that VSCode is failing to lint correctly. Potentially because pip installed something in a place it wasn't expecting. This is my guess, but any help would be very much appreciated.
Edit: Following through on the idea of missing paths, I found this post -- How do I get into the environment VS Code is using for pylance?
Having added the path to where my modules can be found has yielded no results, though I'm not sure if the formatting is correct. Perhaps it needs glob syntax (eg path/**/*)
The issue was indeed with Pylance. It was missing an "additional path" to where pip had installed the projects I wanted to import. To solve the issue:
First make sure you know the location of your import; you can find it with:
$ python
>>> import modulename
>>> print(modulename.__file__)
Then, once you know the location:
Open settings (ctrl + ,)
Search "pylance" or find it under "Extensions > Pylance"
Find the "Extra Paths" config item
Use "add item" to a add a path to the parent folder of the module. It will not do any recursive tree searching
And you should be good to go!
For a further example, you can see the image above where I had added the path /home/seph/.local/lib/python2.7/ to no avail. Updating it to /home/seph/.local/lib/python2.7/site-packages/ did the trick.

I used below solution for importing dependencies.
I found this solution works if I run the code in Pycharm but not in Terminal.
The error message in Terminal is "cannot find graphics.primitive".
I'm using Mac and Python 3.5.
Why I see different behaviors from the Terminal and Pycharm?
How may I make the solution work for both?

Making a Hierarchical Package of Modules
Problem
You want to organize your code into a package consisting of a hierarchical collection of modules.
Solution
Making a package structure is simple. Just organize your code as you wish on the file-system and make sure that every directory defines an init.py file. For example:
graphics/
__init__.py
primitive/
__init__.py
line.py
fill.py
text.py
formats/
__init__.py
png.py
jpg.py
Once you have done this, you should be able to perform various import statements, such as the following:
import graphics.primitive.line
from graphics.primitive import line
import graphics.formats.jpg as jpg
You need to make sure that the graphics package is in the Python search path. PyCharm does this by extending sys.path as follows:
import sys
sys.path.extend(['/Users/hackworth/Development/graphics_parent_dir', '/Applications/PyCharm.app/Contents/helpers/pycharm', '/Applications/PyCharm.app/Contents/helpers/pydev'])
You can do the same in your code replacing /Users/hackworth/graphics_parent_dir with the appropriate path, or you can include the full path to graphics_parent_dir in the PYTHONPATH environment variable. See the Python documentation for details.
Another option would be to place the graphics package into a location the is searched by default on your system.
I'm trying to install the Chilkat library for Python in order to use its encryption functionality, but being new to Python in every possible way, I'm getting stuck entirely too early. I've installed the library as instructed by the docs and verified that the files are in the "right place" (/usr/local/lib/python2.7/site-packages/) on my Ubuntu 12.04 server.
I've also downloaded the test script. When I try to run it, however:
ImportError: No module named chilkat
I know this is stupid basic, but here I am. In the docs they do mention a possible issue with sys.prefix. That (presumably default, since I've never touched it) value on my machine is /usr. I moved everything there, but still get the same error.
Help? Where is the most "pythonic" place to put these files and how can I get Python to recognize them universally?
Thanks.
For anyone searching, I just ended up adding site-packages to my sys.path by adding a .pth file to dist-packages which was already in my path.
echo "/usr/local/lib/python2.7/site-packages" > /usr/local/lib/python2.7/dist-packages/site-packages.pth
i installed django cms correctly but it says no module named menu_pool
do i have to install other menu plugin?
this path from menus.menu_pool import menu_pool i cannot find, what is the problem? can someone please help me find the clue
i followed the django-cms docs as written here: http://docs.django-cms.org/en/2.3/getting_started/tutorial.html#configuration-and-setup
It looks like Python can do import menus just fine, otherwise the error message would be different. A quick search through the docs for menus reveals that you likely want MenuPool instead of your second menu_pool.
If I'm not mistaken, from menus.menu_pool import MenuPool should give you your expected behavior. Then MenuPool will be in your namespace, so you can do nodes = MenuPool.get_nodes(), and anything else you wish.
Not much experience with django but you should check the module files installed on your system itself to see if there is some mistake or not.
You can get the directory address from sys.path variable in python itself.
Most of the time source is installed with python modules, so you can open up those files and see for yourself if this module is really there or not.
Or you can use the dir(menus) to see what modules are there under menus.
