Python: No module named 'numpy' - python

I tried to import numpy but I received a ModuleNotFoundError: No module named 'numpy' error. Someone told me it could be because I didn't have numpy installed, but I already did.
upon installing numpy I got Requirement already satisfied: numpy in ./opt/anaconda3/lib/python3.8/site-packages.
which python returns /Users/MacBook/opt/anaconda3/bin/python. I am new at this, but I'm guessing the reason I got that error was because the files aren't in the same place? If so, how do I move it to the right place?
side note: I have a similar issue with matplotlib and this is running on VS code if that helps. Also I use spyder and I don't get the numpy nor the matplotlib error over there, but the error seems to be on VS code

Try uninstalling numpy and re-installing. You also try re-install anaconda. I had this same issue and that fixed it.

Anaconda installs its own conda environment to run python. Probably VS Code can't access. Try this command;
python -mpip install numpy
If your python file named numpy.py, you can get this error too.
If doesn't work maybe you can try to change the environment to Anaconda environment.

pip list shows module but error shows module not found

I am trying to work with this implementation of the Ramer-Douglas-Peucker Algorithm. I have created a virtual environment, installed the package and checked with pip list. This shows that the package and numpy have been installed.
I checked sys.prefix and it is pointing to the correct venv.
When I try from rdp import rdp I get an error: ModuleNotFoundError: No module named 'rdp'
Looking in the Finder, I can see rdp and numpy in site-packages.
Despite checking many of the similar questions here, nothing seems to quite solve my problem.
Using python 3.8 on MacOS 11.6.5
What can I do?

Module installed in Anaconda, same interpreter with Spyder yet Spyder gets "ModuleNotFoundError"

I have installed the netcdf4 library through
conda install -c anaconda netcdf4
And it shows up fine on my conda environment:
However, when I try to import it in Spyder, I am getting an
"ModuleNotFoundError: No module named 'netcdf4'"
I have tried the solutions here. As you can see below, both the interpreters are the same (in tools/preferences it's set as python.exe, not pythonw.exe):
Yet when I try to import the netcdf4 module, it says there is no module named this.
Any ideas what the cause could be? It's been two days of trying to get Anaconda to work and it has not been a smooth experience at all, really close on giving up on Anaconda as a whole.
Added per request, a screenshot of my entire IDE. Notice in the console I ran pip install netcdf4, where it says I already installed it. Directly below is importing the module and the error:
And how the console looks on each startup:
The docs/tutorial used stated
import netcdf4
While now it is case sensitive
import netCDF4
Such a simple fix..

riginal error was: DLL load failed while importing _multiarray_umath

i got a something weird situation with import packages.
when i use numpy on Jupyter notebook, it's fine and my all source codes are run without problem
but if i use numpy on Visual Studio Code i got a something error.
ImportError: Unable to import required dependencies:
numpy:
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 "C:\Users\Mohw-IN\anaconda3\python.exe"
* The NumPy version is: "1.18.5"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: DLL load failed while importing _multiarray_umath: The specified module cannot be used
다.
and i found something weird.
import os
print("PYTHONPATH:", os.environ.get('PYTHONPATH'))
---------------
PYTHONPATH: None
how can i do for use numpy in vscode?
It appears to be some issue related to path variable. This issue has been discussed on below github link.
https://github.com/numpy/numpy/issues/14770
To solve this, we need to add C:\Users<username>\Anaconda3\Library\bin" in your PATH user variable. Please replace "username" with actual value.
Now VS Code should work fine.
I don't even know what PATH is but i found an easier way to solve the problem
Install Anaconda
Open VScode from anaconda navigator
Done :)
You should be able to use Numpy now
If i open VScode from the desktop shortcut i still have the same problem
I don't now "why" it happens but i don't really care
hope this is usefull
In my case, it was a mismatch between the version of Numpy and Pandas (I had just upgraded to v1.4). Fix by upgrading numpy to sync it with Pandas:
In Anaconda/Miniconda:
conda update numpy
Or with pip:
pip install --upgrade numpy
Or this (very heavy-handed) approach which upgrades all packages:
conda install --update-all numpy
Open Anaconda and Launch Visual Studio. Now run the program.

ImportError: No module named numpy :different

I know this question has been asked few times, however, none of those solutions worked for me, so I thought of reposting the question in my context.
I have downloaded IDLE and Python2.7, and trying to run a python script. The above error is shown. I have verified that numpy is present somewhere in my comp., and I also tried adding 'path' (systems-advanced setting-environmental variables...), however, none of them worked.
Specific question is, is there a way I can install numpy from IDLE?.
Any inputs would greatly help to advance Science!.
Best,

As some of your comments above stated, you have not actually installed NumPy, as NumPy does not come with the base package of Python. My suggestion is to look into python package such as Anaconda or WinPython (only for windows) because these packages come preinstalled with your main python modules (Numpy, SciPy, etc..)
BUT, to just install NumPY, either open your command prompt or a bash shell you should be able to run,
pip install numpy
If you dont have the command pip just run,
python get-pip.py

Matplotlib: Import Error no module named _path

I've been struggling for hours on a problem that is making me insane. I installed Python 2.7 with Cygwin and added Scipy, Numpy, Matplotlib (1.4.3) and Ipython. When I decided to run ipython --pylab I get the following error:
/usr/lib/python2.7/site-packages/matplotlib/transforms.py in <module>()
37 import numpy as np
38 from numpy import ma
----> 39 from matplotlib._path import (affine_transform, count_bboxes_overlapping_bbox,
40 update_path_extents)
41 from numpy.linalg import inv
ImportError: No module named _path
I spent hours on the internet, looking for a solution but nothing worked. I did notice that I am missing _path.so files in the matplotlib directory that everybody seems to have. Instead, I have two files: path.py and path.pyc. But I installed matplotlib directly from the official website using pip install and reinstalling it didn't make any difference. Does anyone have a little clue on what is going wrong? I would be incredibly grateful !!!
For others having this problem, in my case, the solution was simple. The problem was caused by having the wrong matplot library installed on your computer; creating an error in finding the correct matplotlib path. In my case, I had installed matplotlib on a different version of python. Simply update matplotlib on your computer, so that it is compatible with your current version of python:
pip install --upgrade matplotlib
As for the post, I am unsure of what caused these big issues. Hope my tip can help anyone else stumbling upon this issue!
I doubt that most of you brought here by Google have the problem I had, but just in case:
I got the above "ImportError: No module named _path" (on Fedora 17) because I was trying to make use of matplotlib by just setting sys.path to point to where I had built the latest version (1.5.1 at the time). Don't do that.
Once I ran "python setup.py install" (as root) to do a proper install (and got rid of my sys.path hack), the error was fixed.
The package matplotlib requires multiple dependencies (see them here). For me, the missing dependencies included pyparsing and kiwisolver, but your results my vary. Before you do any of these other things (reinstalling python or the library, etc...), make sure you have installed (pip install ...) all the libs in this list (link).
