Unable to import Pandas on Replit.com - Python

I'm unable to import pandas with import pandas as pd on replit.
I've already installed the package with pip install pandas and it can be seen in packages. I've successfully imported it to other projects on replit. Every time I try importing it into my code on this project, it gives me the following error:
Traceback (most recent call last):
File "main.py", line 1, in <module>
import pandas as pd
File "/home/runner/thing/venv/lib/python3.8/site-packages/pandas/__init__.py", line 16, in <module>

ImportError: Unable to import required dependencies:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.8 from "/home/runner/thing/venv/bin/python"
* The NumPy version is: "1.22.2"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: libz.so.1: cannot open shared object file: No such file or directory

You don't need to use pip to install packages on repl.it -- and in fact, you shouldn't! Using Nix derivations not only works better (as you're using their OS distro the way it's designed), but also keeps their storage costs low, by allowing packages to be used from a read-only, hash-addressed, shared store.
Binaries built for other distributions might assume that there will be libraries in /lib, /usr/lib, or the like, but that's not how NixOS works: Libraries will be in a path like /nix/store/<hash>-<packagename>-<version>/lib, and those paths get embedded into the executables that use those libraries.
The easiest thing to do here is to create a new bash repl, but to add a Python interpreter to it. (I suggest this instead of using a Python repl because the way they have their Python REPLs set up adds a bunch of extra tools that need to be reconfigured; a bash repl keeps it simple).
Create a new bash repl.
Click on the three-dots menu.
Select "Show Hidden Files".
Open the file named replit.nix
Edit the file by adding a Python interpreter with pandas, as follows:
{ pkgs }: {
deps = [
pkgs.bashInteractive
(pkgs.python38.withPackages (p: [p.pandas]))
];
}
...changing that to taste (as long as they're getting software from a channel that has binaries for Python 3.9 or 3.10, for example, you can change python38 to python39 or python310).
Click the "run" button
In the new shell that opens, run python, and see that you can import pandas without trouble.
If, after you add a Python file to your repl, you can also change the .replit hidden file to make it run that file automatically on startup. Note that on NixOS, you should use #!/usr/bin/env python as your shebang, as PATH lookups are essential.

library installed in site-packages but not in lib folder

I was trying to use urllib library but an error was shown
import urllib.request
Traceback (most recent call last):
File "E:\coding\python for everybody\third part\urllib.py", line 1, in <module>
import urllib.request
File "E:\coding\python for everybody\third part\urllib.py", line 1, in <module>
import urllib.request
ModuleNotFoundError: No module named 'urllib.request'; 'urllib' is not a package
process is terminated with return code 1.
I installed urllib3 using pip but, the package was installed in roaming/python/python39/site-packages.
While the path is set to C:\Program Files\Python\scripts. The folders python39 and python are located in different folders. Also, upon checking I found that package urllib was installed already C:\Program Files\Python\scripts.
I don't know how python is accessing the packages and how it determines the location as none of the packages are being imported (except random and other preinstalled packages).This problem has been very problematic not only this time but many times before.
PS: some time ago I deleted python (6 months approx) and at that time python was installed in roaming is this the result of that?
I am also using anaconda distribution, but the above code was being written in sublime text(Windows 10).
UPDATE: ISSUE WAS SOLVED BY CHANGING THE FILE NAME(LOOK IN THE COMMENTS)

If you are using code editors like VSCode, Notepad+++ and not PyCharm or other python IDE. I think you should check your path and make sure that you have same python version.

Your filename is the same as the library that causes confusion, please change the name as python will get looking at the working directory for import hence the error

Terminal says, that “successfully installed openpyxl 6.2.2“ but I can't import it in IDLE ; why? (python, beginner)

I am a total beginner in terms of programming. Currently, I am working with this book https://automatetheboringstuff.com/2e/appendixa/.
In chapter 13 I need to install the openpyxl module. I did it exactly as the book told me to do, and my terminal confirms that it is installed. The same way I installed my pyperclip module ( which worked), but this time, every time I try to import it, it tells me, no module named openpyxl
Traceback (most recent call last):
File "", line 1, in
import openpyxl
ModuleNotFoundError: No module named 'openpyxl'
I have the newest version of python, and I tried openpyxl 2.6.2, or 2.6.1, but it is always the same.
I hope someone can help me, in another forum It was suggested to download Pycharm or Anaconda, but this is nothing that the book requires, and I have to stick to the instruction ( it is a university work).
Thank you!

can't import pyd file from scipy

trying to import scipy.interpolate but it can’t import _fblas.pyd. It keeps throwing the following error
File "C:\cygwin64\lib\python2.7\site-packages\scipy/linalg/blas.py", line 155, in <module>
from scipy.linalg import _fblas
ImportError: cannot import name _fblas
My online research suggested that this is because I had the wrong version of numpy installed, and I need to install numpy+mkl. So I uninstalled the version I had and pip installed numpy 1.10.4, which includes mkl.
This did not fix the original problem with _flbas.pyd.
I would reinstall scipy but I can't remember where I got the version I have, and when I pip install scipy 0.17.1.tar.gz it throws an error saying that it has no blas resources, which are necessary. I've also tried to download it from here: https://github.com/scipy/scipy/releases, but they don't include _fblas.pyd in the first place.
I’m not sure where to go from here. I'm not even entirely sure why it won't import the _fblas.pyd file.

This looks like you tried to manually comply to your needed packages. Even though I take my hat off at your effort, keep in mind that this is not an simple task at all.
I might also add that this kind of work is not meant for a developer ("the person who writes the code"), but a full time maintainer. Specially with your particular Cygwin environment
So, what can you do? Alternatively, you can use one of Continuum's mkl-ready python-and-many-tools-including-mkl+scipy distribution or Enthought's Canopy. Hopefully, this will avoid you lots of hours of staring at the screen wondering what's wrong

Trouble importing Python modules on Ninja IDE

I have been trying to import modules into Ninja IDE for python. These are modules that I have working on the terminal (numpy, scipy, scitools, matplotlib, and mpl_toolkits), but will not run correctly in Ninja.
First I was only getting the message No module named ____. I checked sys.path and found that the path was within the application
/Applications/Ninja IDE.app/Contents/Resources/lib/python2.7 was a typical path. I tried changing the path,but it doesn't seem to do anything to sys.path even after restarting the ide.
But I wanted the path to refer to where the modules are stored (which is /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages). I was able to get numpy and scipy to work as well as parts of mpl_toolkits by adding the contents of my path to the folders that sys.path gave. However, I still can't get fully functioning modules within the ninja ide interpreter. I'll give some examples below of what happens when I import certain modules.
import matplotlib.pyplot
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/Applications/Ninja IDE.app/Contents/Resources/lib/python2.7/matplotlib/__init__.py", line 106, in <module>
ImportError: No module named sysconfig
import mpl_toolkits
from mpl_toolkits.mplot3d import axes3d
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/Applications/Ninja IDE.app/Contents/Resources/lib/python2.7/mpl_toolkits/mplot3d/__init__.py", line 1, in <module>
File "/Applications/Ninja IDE.app/Contents/Resources/lib/python2.7/mpl_toolkits/mplot3d/axes3d.py", line 14, in <module>
File "/Applications/Ninja IDE.app/Contents/Resources/lib/python2.7/matplotlib/__init__.py", line 106, in <module>
ImportError: No module named sysconfig
Thanks for the help. I apologize, I am very new to programming, but I did put in about a day and a half of research before posting here.

That's strange as the sysconfig module is a part of Python 2.7 standard library.
Are you sure that Ninja is using the right Python version? Try running:
import sys
print sys.version_info
from Ninja, to see which Python version it is actually using.

I know this question is a few months old, but I wanted to post my solution in case others find it useful. I had a very similar problem, and had a lot of trouble finding a quick workable solution anywhere.
My somewhat roundabout solution was to simply create a virtualenv folder with the version of numpy I wanted, and then pointed the "virtualenv" property for NinjaIDE project to that folder. I restarted NinjaIDE and boom, instantly worked.
To set the virtualenv property for your project via the GUI, go to the Project menu:
Project > Open Project Properties > Project Execution,
and you should see a variable called "Virtualenv Folder". Point that to the folder for your virtualenv, and it should work. (May need to restart NinjaIDE.) This worked for me, NinjaIDE version 2.2 under Ubuntu 12.04.
One quick note: I actually didn't use virtualenv exactly -- I had to use a "conda env," since I am using the Anaconda distribution, and apparently it is not well-tested with virtualenv yet. (I actually got a warning when I went to easy_install virtualenv. Hadn't seen that before.)
Either way, this stackoverflow question has some nice pointers to virtualenv tutorials: Comprehensive beginner's virtualenv tutorial?
Good luck!

I was having a similar problem trying to import a module from /home/paul/lib/python using the console of the Ninja-IDE. I found out that /home/paul/lib/python didn't appear in syspath when checking in the console of the Ninja-IDE. But it did in the terminal!
By starting the Ninja-IDE from the terminal, /home/paul/lib/python was in syspath when checking in the console of the Ninja-IDE. I was now able to import the module I needed.
I hope this might be of some help. If not to ebris1 than maybe to others.
