I have a long code with a series of imports. For days now I've been running and rerunning this code, including all the imports, for every small change I make (all variable-related, not touching the modules). I keep doing this when suddenly, one time, I get a ImportError: cannot import name _distributor_init upon running import numpy as np. I am, of course, 100% certain that whatever change I made has nothing to do with this import, especially as this is the first executable line in the file, but regardless I reverted that change yet the error continues.
Following some other threads on StackOverflow I tried reinstalling by doing conda install numpy --force-reinstall, this is because in PyCharm and the conda prompt I can clearly see that numpy is installed and up to date.
According to this thread, I tried running from the console, and according to a comment here I tried commenting out the respective line in the __init__.py file, but somewhat expectantly none of that worked.
I am using Miniconda3 and the environment runs Python 3.7. IDE is PyCharm in which the interpreter is the aforementioned environment.
The full error is:
Traceback (most recent call last):
File "<input>", line 7, in <module>
File "C:\Program Files\JetBrains\PyCharm 2019.1.3\helpers\pydev\_pydev_bundle\pydev_import_hook.py", line 21, in do_import

File "C:\Users\OfirL1\Miniconda3\lib\site-packages\numpy\__init__.py", line 140, in <module>
from . import _distributor_init
ImportError: cannot import name _distributor_init
Aside of having numpy import as usual, which would be nice, I'd love to know what went wrong. This is not the first time that during normal work one module suddenly stops working all of a sudden for no apparent reason.

I wanted to use OpenCV library for my project (in python) so I made a virtual environment in which I installed said library (numpy was automatically installed with it). It worked at first, but when I tried to run a separate python file in the same venv it just redirected it into the numpy library where it showed attribute error in one of its functions. After that, the first file didn't work either.
Error looks like this (the script was run from a command prompt inside VS code):

Besides that I also got a message that a power shell file (which is inside the virtual environment) can't be run because of restrictions:

I tried running the code inside that terminal and the second error didn't show up anymore, but the first one stayed the same.
I also tried to update pip and reinstall the libraries and when that didn't work I made a new virtual environment, but the error persisted.
Working with libraries and virtual environments is all still new to me so I probably messed up the setup.
Thanks in advance to anyone who tries to help me with this problem.
I'm on Windows 10 and working in a git-bash terminal with anaconda environment. When I open a new terminal, I'm immediately presented with:
Error processing line 1 of C:\Users\e360769\AppData\Local\miniforge3\lib\site-packages\distutils-precedence.pth:

File "<string>", line 1, in <module>
ModuleNotFoundError: No module named '_distutils_hack'
Remainder of file ignored
This same error comes up any time I run "pip" or "python" on the command line. The command still executes correctly, but only after displaying that error. Note that this started after installing a collection of packages needed for a project I'm working with, and after investigating I found some people attributed this to the setuptools package (I have v41.2.0), but even when I uninstall it, the issue persists. Also note that this is the contents of my distutils-precedence.pth file:
import os; var = 'SETUPTOOLS_USE_DISTUTILS'; enabled = os.environ.get(var, 'local') == 'local'; enabled and __import__('_distutils_hack').add_shim();
I'm not sure this is actively (for now) causing any issues with executing my python scripts, etc., but I'd like to know what's going on and how to fix this. Would appreciate any help!
I am struggling to install and import python libraries into my programs. originally I was using pydev but I kept getting messages like:
Traceback (most recent call last): File "C:\Users\satur\eclipse-workspace\DMD experimental\Main.py", line 11, in <module> from matplotlib import pyplot as plot ModuleNotFoundError: No module named 'matplotlib'
I installed matplotlib using py -m pip install matplotlib which produced a few messages like this.
WARNING: The script f2py.exe is installed in 'C:\Users\satur\AppData\Local\Programs\Python\Python310\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. WARNING: The scripts fonttools.exe, pyftmerge.exe, pyftsubset.exe and ttx.exe are installed in 'C:\Users\satur\AppData \Local\Programs\Python\Python310\Scripts' which is not on PATH.
I was unsure what this meant so I tried running my program again and got the module not found error again.
being unable to resolve the issue I moved over to spyder because it came with many of the libraries I wanted thus avoiding the issue. however, as soon as I tried to import and install libraries not included with spyder I encountered the module not found error and a similar warning about the path. I added the paths mentioned in the warning to the PATH in spyder now when I run my code get this error message:

I did some looking around and found this
https://github.com/spyder-ide/spyder/wiki/Working-with-packages-and-environments-in-Spyder#installing-packages-into-the-same-environment-as-spyder
I followed what instructions I understood
import sys; sys.executable

which is different from what I get when I run it in command prompt or in the pydev terminal both of which give me

when i go to C:\Users\satur\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\ I see: 3 versions of idel, 3 versions of pip, and 6 versions of python.
I am deeply confused. I want to install and import libraries into my python programs. I want to be able to run my programs in either (or for that matter any) ide. I seem to be hitting the very similar issues in both. every tutorial I have found online describes the steps to take to do this but not what they are or why I am doing them none of them seem to work and the more times I try to install things the more confused I get.
could someone please explain: how to install and import libraries into a python program. what python is doing when I install things and try to import them. and why both IDEs have similar but different errors.
I have a cloud instance of a Linux machine (openSuSE) with multiple users.
I have created a virtual environment and installed all my required libraries (including Klein).
I have two users "a" and "b".
While logged in as "a" and inside virtualenv, when I open python shell at home directory and type
import klein
it imports normally.
Now when I change directory to
/home/b/
and run the same (open python shell, import klein) while being in the same virtualenv, it gives me an error.

#attr.s
AttributeError: module 'attr' has no attribute 's'
Command "which python" gives same address at both location which is my virtualenv python address and that should be expected.
But what causes this weird python shell behavior.
Thank you
I solved it and a very shameful reason caused the error.
One of the modules Twisted uses is "attr" module. I had named one of my files attr.py and that is what was causing all the error.
I myself am not deleting this question if moderation has no problem, maybe somebody like me might be stuck at the same situation. It may help them.
Never name your python files same as that of any standard module unless overriding.
Also if your issue persists, then Jean's answer will definitely resolve it.
There can be multiple different Python packages that provide the same Python module. For example, there are at least two packages that provide the attr module:
https://pypi.org/project/attr/
https://pypi.org/project/attrs/
It's possible you've installed the wrong package based on the requirements. You can check what you have installed with pip freeze.
Dreamhost upgraded a number of servers this weekend, including the one I was on. It broke my configuration, so as recommended I attempted to delete the virtual environment it was running on and attempted to re-set it up. However, when I try to navigate to the site, I get this:

from _weakrefset import WeakSet
ImportError: No module named _weakrefset
I've got Python 2.7.8 installed and running, and from shell access, both in and out of my virtual environment when I run Python, I'm pulling up the correct version (which is different from the native version installed, so it's finding my setup). Other posts which reference this error message seem to think it's a problem with not having an upgraded version of virtualenv, but its version is higher than the troublesome version. (I'm running 1.11.6.)
Weirder still, I can shell into Python, type from _weakrefset import WeakSet, and I don't get import errors. I'm running Django 1.6 and I can python manage.py runserver with no errors, but the web server is throwing up before it ever sees Django.
In the traceback, the first two lines are pulling from my virtual environment, but the remaining ones don't seem to be, and I have no idea why, or even if that's relevant.
Any advice on what I should do next? I've about pulled my hair out on this one! I can post any additional information that would help troubleshoot. Thanks!
Well, I feel silly now. I went to the /home/thesp/lib/python2.7/ directory and downloaded _weakrefset.py, like so:
wget http://svn.python.org/projects/python/trunk/Lib/_weakrefset.py
...and now everything seems to be running fine. There was a _weakrefset.pyo file in the directory, so I'm not sure why _weakrefset.py never made it in, but this seems to have done the trick.
Now, that doesn't solve the mystery of why the stack trace switches directories like it does, but it's running now, so I'll take it for now!
