I am building a desktop app using the python library Kivy. Since I installed a plugin to be able to visualize .kv files, I am not able to debug my code. Yet I am able to run it without problems. This is the error I keep getting:
Traceback (most recent call last):

from os.path import dirname, join, exists, sep, expanduser, isfile
ImportError: cannot import name 'sep' from 'ntpath' (...\AppData\Local\Programs\Python\Python310\lib\ntpath.py)
So far I do not understand where this ntpath stands for. I tried to compare the ntpath while debugging and while running and they are the same. I also double checked that the interpreter set for the prrject and the interpreter in the run/debug configurations are the same.
I tried with and without the usage of a venv .
Does anyone have an idea why I can run this app but not debug it?
Appreciate much the help!
I had the same problem a while ago. You can either edit the \lib\site-packages\kivy\app.py in your virtual environment to remove the sep from that import line on line 416.
It will look like this after you remove the sep.
from os.path import dirname, join, exists, expanduser, isfile
Or
Update to the latest version of kivy which no longer gives me the error.
You can update to the latest kivy developer build with this command:
python -m pip install "kivy[base] # https://github.com/kivy/kivy/archive/master.zip"

I am building an python project with Eel, and I'm trying to package my program to an exe with PyInstaller as instructed in the documentation. However, I get the following error when I open the .exe:
Error

AttributeError: 'NoneType' object has no attribute 'write'
I tried to use auto py-to-exe instead of Pyinstaller, but I got the same error. Finally, I tried to package the Eello world example from the Eel documentation to see if it was my program that was the issue, but I still got the same error. I found a similiar problem in a github issue, but I fail to see what I should attach to --add-data.
I am running Python 3.10.8 and Eel 0.14.0. I've now tried python 3.8.9 and python 3.9.13 without luck.
Update
Upon further investigation, I discovered that the error only occours when I attach --noconsole at the end of my cmd python -m eel hello.py web --onefile --noconsole . However, I want my app to work without a visible console.
One of the libraries you are using is attempting to write to sys.stdout and sys.stderr, which are set to None when you run pyinstaller with --windowed option.
You need to explicitly set sys.stderr and sys.stdout in your programs code as early as possible to a writeable object like an open file or an io buffer.
for example:
import sys
outfile = open("logfile.txt", "wt")
sys.stderr = outfile
sys.stdout = outfile
Set-up
After updating to Catalina, Anaconda3 trouble commenced.
I've managed to solve most errors, doing a fresh install as advised by Anaconda, but can't seem to get around a permission error when trying to importing functions from other .py files – something that worked just fine before I upgraded to Catalina.
I run Python 3.7 from Spyder 3.3.6.
Error
Whenever I try to import a custom function, I get,
import os
os.chdir('/Users/mypath/payment_management')

Question
How do I run Anaconda/Spyder/Python with admin permission? Which command in terminal do I need to execute?
Stupidly enough I have actually managed to run with admin permission before via Terminal, but I forgot how...
I've been looking at StackOverflow for an hour now, but can't find anything that helps.
You've probably forgotten again how to do this. Use sudo spyder, dummy.
I am working on MacOS and I am trying to use PyInstaller to circulate a script to some non tech colleagues. The script is imaginatively called script_V1.py and runs fine.
Up to now, I have had issues with PANDAS and SCIPY but they seem to be resolved with with the command
pyinstaller --onefile --hidden-import pandas._libs.tslibs.timedeltas --hidden-import scipy._lib.messagestream script_V1.py
However, I am now getting a different error (I'll post the full error below)
RuntimeError: Python is not installed as a framework. The Mac OS X
backend will not be able to function correctly if Python is not
installed as a framework. See the Python documentation for more

backends. If you are using (Ana)Conda please install python.app and
replace the use of 'python' with 'pythonw'. See 'Working with

I have tried the solution in a similar question on Stack Exchange:
Installation Issue with matplotlib Python
But I think that is actually a different problem with import statements not working within the script itself. In my case if I run the script as a .py script it works fine. Anyway adding the suggested file did not alter the error message. Im new to this and seem to be really struggling with PyInstaller (more than with python itself) so any help much appreciated.
The full error message is (I've added line breaks for clarity)

So the way I got this to work in the end was to force Matplotlib to use WebAGG and also install the 'tornado' package (which is needed for some reason).
I am having issues with the standard logging module. If I open a python2.7 shell and import logging everything works fine:
$ python
>>> import logging
>>>
But if I open a python3.4 shell and import logging I get the following error:
$ python3.4
>>> import logging

I have no idea what the problem is and can't seem to find anyone else who has had the same issue.
logging module is by default there in Python 3 environment .No need to import it.
You seem to have installed a third party library called logging in your Python 3 environment, which is hiding the standard library version, and one of its files has a typo.
I stupidly created a file called logging.py to try out some log features. Then when trying the code below, it is effectively referring to itself and can't find the debug method.
import logging
logging.debug("Debug message")
Changing my file name to logtest.py fixed the problem.
for me it was the previous install of a logging library under an older Python version.
pip3 uninstall logging
fixed it for me.
I'm trying to import a sub-module programmatically. My file tree looks like this:
oopsd/__init__.py
oopsd/oopsd.py
oopsd/driver/__init__.py
oopsd/driver/optiups.py
The optiups.py simply prints "Hello World".
The oopsd.py looks like this:
import importlib
importlib.import_module('oopsd.driver.optiups')
Now with this, I'm getting this exception:
Traceback (most recent call last):
File "<frozen importlib._bootstrap>", line 1521, in _find_and_load_unlocked
AttributeError: 'module' object has no attribute '__path__'
During handling of the above exception, another exception occurred:

ImportError: No module named 'oopsd.driver'; oopsd is not a package
Does __path__ even still exist in Python 3?
I also tried importing .driver.optiups instead, but this yields:
TypeError: relative imports require the 'package' argument
__package__ seems unset, so I'm lost.
How do I do this the right way?
This is an old question, but since it was bumped, the other answer is totally wrong, and this is a common problem:
You're probably doing this.
python oopsd/oopsd.py
Don't do this. :)
Specifically, NEVER try to directly run a file that's part of a parent package. When you run python FILENAME, Python adds the file's containing directory to sys.path, and DOESN'T add the current directory. So you have oopsd/ in your path, and every module in oopsd/ just became a top-level module. Python has no way of even knowing that any of them are supposed to have an oopsd. prefix, because the parent directory doesn't exist anywhere in sys.path.
If you want to execute a module directly, do this:
python -m oopsd.oopsd
This puts the current directory in sys.path and ensures that imports of your source tree work as you'd expect them to.
Alex Z's answer is wrong because it doesn't actually fix this problem, and it's not a relative import — implicit relative imports no longer exist in Python 3.
This works for me (relative path to driver):
import importlib
importlib.import_module('driver.optiups')
(karthikr in comments was close, but you don't seem to need the leading .)
