I am trying to better understand importing modules. I read about how to do this from here https://stackoverflow.com/a/14132912/14179793 and I can get it to work using solution 1. There is an additional variable that I need to figure out though.
This is a dummy project I am testing with:
.
├── a_package
│ ├── __init__.py
│ └── lib_a.py
├── b_package
│ ├── __init__.py
│ └── test_script.py
├── main.py
└── src
└── src_lib
└── src_lib.py
With this setup I can do:
python -m b_package.test_script
this is lib a function
This is src_lib_function.
test_script.py:
from a_package.lib_a import lib_a_function
from src.src_lib.src_lib import src_lib_function
if __name__ == '__main__':
lib_a_function()
src_lib_function()
pass
The goal is to make b_package/test_script.py executable without using python test_script ie ./test_script
However, adding the shebang at the top #!/usr/bin/env python causes an import error:
$ ./b_package/test_script.py
Traceback (most recent call last):
File "./b_package/test_script.py", line 2, in <module>
from a_package.lib_a import lib_a_function
ModuleNotFoundError: No module named 'a_package'
I assume it is because python is not loading it as a module based off the above mentioned question but I am not sure how to resolve this.
I ended up using setuptools as suggested by kosciej16 to achieve the desired results.
New project structure:
.
├── a_package
│ ├── __init__.py
│ └── lib_a.py
├── b_package
│ ├── __init__.py
│ └── test_script.py
├── main.py
├── pyproject.toml
├── setup.cfg
└── src
├── __init__.py
└── src_lib
├── __init__.py
└── src_lib.py
setup.cfg:
[metadata]
name = cli_test
version = 0.0.1
[options]
packages = find:
[options.entry_points]
console_scripts =
test_script = b_package.test_script:main
This allows the user to clone the repo and run pip install . from the top level then they can execute the script by just typing test_script

My python project is structured in the so called src-layout.

I am not able to get coverage running for it. How can I do this?
What I tried so far
Run coverage in the projects root folder just gives me Nothing to run.
Or coverage run ./src/hyperorg gives me
Traceback (most recent call last):
File "/home/user/tab-cloud/hyperorg/src/hyperorg/__main__.py", line 6, in <module>
from .content import Content
ImportError: attempted relative import with no known parent package
One of the ways of doing that is entering the src folder by cd src and then running coverage from there as following:
coverage run -m unittest discover -s ../tests
You can also leverage rcfile (default .coveragerc) to specify configurations and change HTML report path to be created outside the src folder as well.
I made a very simple python package by following the packaging guide:
tester
├── A.py
├── B.py
└── __init__.py
The contents of A.py are simply:
import B
__init__.py and B.py are empty files.
I uploaded the package to testpypi and installed it in a virtual environment. I started first by checking if it works by making a simple test.py file:
from tester import A
Then I try to run that file:
(scratch-venv) [ccn#sy337b4 scratch-box]$ python test.py
Traceback (most recent call last):
File "/home/ccn/scratch-box/test.py", line 1, in <module>
from tester import A
File "/home/ccn/scratch-box/scratch-venv/lib/python3.9/site-packages/tester/A.py", line 1, in <module>
import B
ModuleNotFoundError: No module named 'B'
I'm confused because when I was developing the package running python A.py never caused an error, but now when I'm importing A it doesn't work any more.
(within the venv, aka: client using package) I was able to fix this by changing the contents of A.py to :
from tester import B
But that's not a solution because when I go back to developing the package I get this error when running python A.py
Traceback (most recent call last):
File "/home/ccn/tester_package/src/tester/A.py", line 1, in <module>
from tester import B
ModuleNotFoundError: No module named 'tester'
Finally for full context I will post the structure of the package. I am developing in src/tester

If I remember correctly, in tester/a.py you should have either one of those:
from . import B
from tester import B
import tester.B
I have a python project and want to write a command line launcher. My project works fine when I run tests or launch from my IDE (pycharm). However when I try to launch via the command line I get a ModuleNotFoundError: No module named 'python' error.
Here is my directory structure:

The shell script create_jenkins_jobs.sh contains:
#!/bin/bash
python3 python/create_jenkins_jobs_cli.py "${#}"
the file create_jenkins_jobs_cli.py contains the following code:
from typing import Set
from shared.common import preflight_env_check
from python.jenkins_multibranch_job_builder import JenkinsMultibranchJobBuilder
def configure_jenkins_jobs(git_repos: Set[str]):
jenkins_job_builder = JenkinsMultibranchJobBuilder(jenkins_server_url=JENKINS_BASE_SERVER_URL,

git_cred_id=GIT_SSH_CRED_ID,
git_repos=git_repos)
jenkins_job_builder.configure_jobs()
configure_jenkins_jobs(GIT_REPOS)
When I launch create_jenkins_jobs.sh or create_jenkins_jobs_cli.py I always get
ModuleNotFoundError: No module named 'python'
$>./create_jenkins_jobs.sh
/Users/pswenson/dev/cc-cicd-automation/.venv/bin/python3: Error while finding module specification for 'python/create_jenkins_jobs_cli.py' (ModuleNotFoundError: No module named 'python/create_jenkins_jobs_cli')
I've tried all sorts of different techniques to get this to work with PYTHONPATH, working directories, etc...
It seems there is something basic about how python modules work that I don't understand.
Does changing the line:
from python.jenkins_multibranch_job_builder import JenkinsMultibranchJobBuilder
to
from jenkins_multibranch_job_builder import JenkinsMultibranchJobBuilder
Sort you?
I installed a package in my anaconda environment by entering the following line:
pip3 install -e git+https://github.com/gauravmm/jupyter-testing.git#egg=jupyter-testing
I keep getting ModuleNotFoundError: No module named 'testing' on line: from testing.testing import test. I have no idea why this is happening, and believe it has something to do with the way my directory structure is set up.
My directory tree looks like this:

I am trying to use this module : https://github.com/gauravmm/jupyter-testing.git#egg=jupyter-testing to do some testing in an online class.
I appreciate any help and explanation as to what I am doing wrong! :)
I'm new to python and I am trying to write a simple program for an led cube. First I need to execute one of the other sample programs provided, but I'm getting the error "No module named cube_interface" when I try and run a python program.
Now before you mark this question as duplicate, and refer me to the 7,776 similar questions stack overflow, let me tell disclose that I've already tried implementing the solutions provided on 14 other SO questions, and followed 3 blogs covering how to fix this error, with no luck.
OS: Mac OsX 10.8.1
Python: 2.7.5
Repo: https://github.com/chadharrington/all_spark_cube
The example program is src/tetris.py
The module is src/all_spark_cube_client

When I try and run the tetris.py program, I get an error "No module named.."
python tetris.py
Traceback (most recent call last):
File "tetris.py", line 5, in <module>

Many of the answers suggest adding pwd . /Library/Python ect.. to the PYTHONPATH. I've tried implementing all of them independently, and even combined all suggestions into one frakenstein path as shown, with no luck.
cd ~/Code/all_spark_cube/software/clients/python_client
export PYTHONPATH=$PATH:$PYTHONPATH:`pwd`:`pwd`/src:.:/Library/Python/2.7/site-packages/
I've tried building the python module
$sudo python setup.py build
running build
running build_py
file all_spark_cube_client.py (for module all_spark_cube_client) not found
file all_spark_cube_client.py (for module all_spark_cube_client) not found
I've tried installing the python module (It doesn't give any errors, but I still am unable to run tetris.py)
cd ~/Code/all_spark_cube/software/clients/python_client/src/
sudo python setup.py install
How can I execute the tetris.py program?

You forgot to build cube_interface:
See: https://github.com/chadharrington/all_spark_cube/tree/master/software/thrift
You need to build this with the gen_py tool.
i.e: (I assume:):
cd /path/to/all_spark_cube/software/thrift/
make
cp cube_interface.py /path/to/python/site-packages
