I am currently working with converting Pycrypto over to Python 3.X
Whilst I seem to have the cryptography side working the same cannot be said for the tests
provided with the module :(
I have used the tests under Python 2.64 and all works fine.
I then ran '2to3' over the tests to generate new files in 3.X format.
There are several references to the following:
from .common import make_block_tests
Whenever I run the tests I get:
ValueError: Attempted relative import in non-package
If someone would point me towards a way to fix this it would be much appreciated :)
Cheers

You are trying to run the test files directly, then you can't have relative imports. Change them to be absolute imports, and it will solve the problem.

The python version I am using is 3.8.2
I searched a lot and most of the solutions are to use sys.path.append()
But it didn't solve the problem for me, if I use from . import players
it will say
ImportError: attempted relative import with no known parent package
if i use import players it will say
ModuleNotFoundError: No module named 'players'
The code I used to fix this:
sys.path.append(".")
sys.path.append(os.getcwd() + "\\players.py")
sys.path.append(os.getcwd())
still can't fix this,It's worth mentioning that at some point sys.path.append(os.getcwd() + "\\players.py") can run
Make sure that the name of the file is actually players.py.
And not for example players.py, players .py (note the spaces).
Also check for all other "invisible" Unicode characters that would not necessarily show up.
And make sure that there is no directory players as well.
I deleted the file completely so I couldn't test it, but I ran into this problem again, it's an import order problem, I tried to import attributes.py first and then content.py, there was a problem Check, can't find attributes.py , the problem is solved when their import order is swapped, I can't understand why, but if you encounter such problems please try once (other files are not imported)
I've had similar issues and I've created a new, experimental import library for Python to solve this kind of import error: ultraimport
Instead of from . import players it allows you to write
import ultraimport
players = ultraimport('__dir__/players.py')
This will always work, no matter how you run your code, no matter what is your current working directory and no matter if there's another directory somewhere called 'players'.
i'm new to python and literely trying to import the module toolbox in the createRecipe.py file. Please see picture as it describes my problem
importProblem
I've looed in over 30 resources on the Internet and it seems there is no working solution for it. Though, i would like to raise the problem again, perhaps there is something new in python which makes this possible
I am trying to start a project to learn how to use opencv and the first problem I encountered is this : "Module 'cv2' has no ---- member pylint(no-member) as posted in the picture.
I have found some information here in Stack Overflow but I'm afraid, I might not be proficient enough to understand what is going on. Could someone point me in the right direction to solve my problem?
Thanks!
One possible reason is that you might have a file named cv2.py somewhere on your machine other than the original cv2 module and now python is importing that file rather than the cv2 module.
Or perhaps you could've downloaded a wrong cv2 module, other than that i don't see anything that could've gone wrong as you don't have a complex code. Try reinstalling the module and/or removing a file named cv2.py (if you've accidentaly created one).
You can check the module by importing the module in the terminal and check for dir, on python console type import cv2 and then dir(cv2), now you should see all the classes contained in the cv2 module.
If the program runs correctly then I guess you are facing linting issue which is answer in this [https://stackoverflow.com/questions/26657265/hide-some-maybe-no-member-pylint-errors] question.
Solution is to turn off no-member linting error using below command
pylint disable=maybe-no-member
OR
pylint --disable=E1101
I am trying to run the Breusch-Pagan test in python 3 using the below code. It works perfectly in python 2.7, but when I run it in Anaconda with python 3.6 instead, I get the following the error: "module 'statsmodels.stats.api' has no attribute 'het_breuschpagan'".
I have looked at the statsmodel documentation at this link, https://www.statsmodels.org/devel/generated/statsmodels.stats.diagnostic.het_breuschpagan.html, and know that I am running the right code.
import statsmodels.stats.api as sms
breuschpagan_test = sms.het_breuschpagan(model_run.resid, model.model.exog)
Does anyone know a solution to this or a different way to call this statsmodel function in python 3?
Also, due to limitations at work, I cannot uninstall/re-install or update my statsmodel library at the moment either.
Thanks in advance!
I have been trying to import tinytag into python to be able to read mp3 tags but I keep receiving the same error. This is the code I am running
from tinytag import TinyTag
tag = TinyTag.get('/some/music.mp3)
print(tag.album)
and the error I recieve from this is
ImportError: No module named 'tinytag'
If anyone could give me any information on how to fix this would be greatly appreciated or can suggest another reader to use that is compatible with python 3.
Like you, I'm new to Python and I struggled with this but I worked it out eventually. I'm sure there is better way, but this worked (on windows, with my examples)
I installed a python module called easy_install (bundled with
setuptools). you can Google this. In the directory \Python26\Scripts you should see an exe file called easy_install if this has worked
Then I downloaded TinyTag to my pc eg
\downloads\tinytag-0.6.1.tar.gz
Then in note pad I wrote a small text file called myinstall.bat with
the contents
easy_install C:/downloads/tinytag-0.6.1.tar.gz
pause
then saved it into \Python26\Scripts and ran it (the pause keeps the
window open so you can see it worked)
Subsequently I started using some software called JetBrains to code with (it's commercial but there is a free edition) and that has an install tool built in which is even easier) I hope this helps
