I installed matplotlib using conda:
conda install matplotlib
The following code failed:
#!/usr/bin/env python
import matplotlib
import matplotlib.pyplot as plt
With this error message:
"ImportError: No module named 'matplotlib.pyplot'"
I tried installing matplotlib with apt-get:
sudo apt-get install python3-matplotlib
I got the same error.
I tried loading matplotlib with ubuntu application load and got the same error.
I tried cloning from GitHub with:
git clone git://github.com/matplotlib/matplotlib.git
I got the same error.
I looked at the matplotlib directory and did not see a pyplot.py entry. I did find pyplot.py in matplotlib/lib/matplotlib. I copied it to matplotlib. The error went away, but I got another module that pyplot was trying to include. I found it in matplotlib/lib/matplotlib. I copied it to matplotlib. Got another error for another module. Copied it. Eventually I got an error for a module I could not find.
I do not know what to try next.
Normally conda isn't added to your path (it asks you during the installation if it should do that but the default is "no"), so the default python will be the systems Python 2 (you start Python 3 with python3).
You could verify this by using:
$ which python
That will return the path associated with the python command. Likely this will return the path to the systems Python 2 "installation".
For example on my Ubuntu machine the commands which python and which python3 return:
usr/bin/python (starts Python 2.7.12)
usr/bin/python3 (starts Python 3.5.2)
While my conda installation is somewhere in the /home/michael/miniconda directory.
There are several options how you could use the conda Python:
Temporarily add the conda directory it to the PATH. (See for example How to add [...] to path)
Permanently add the conda directory to the PATH. (see for example How to add a directory to the path)
Use the anaconda promt which gives you a terminal with the conda directory prepended to the PATH.

This is the complete error message I received:
ImportError:
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: Python3.10 from "D:\hugging-face\nlp\Scripts\python.exe"
* The NumPy version is: "1.21.5"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'
I checked my Python version by typing python -v it the output was 3.10.5 is that alright?
I tried checking the NumPy version by typing:
import numpy
numpy.version
However, it gave me the same error about numpy.core.multiarray_umatch`. So, I tried to install numpy by running the following command:
pip install numpy
It gave me the following error:
ImportError: cannot import name 'Mapping' from 'collections' (D:\python\lib\collections\__init__.py)
I would also like to add that there are two directories inside lib with names numpy and numpy-1.21.5.dist-info. So, I guess the library is already installed but I can;t use it for some reason.
The contents of my pyvenv.cgf file are:
home = D:\python
include-system-site-packages = false
version = 3.7.4
What should I do?
This may work, just give it a try
as you are using python 3.10 you need to install numpy version greater than 1.21.5
create new environment
cd <path where you need your virtualenv>
python -m venv .venv
as you are using windows activate using virtual env
.venv\Scripts\activate assuming your are already in the virtualenv folder
then try pip install numpy>=1.23
I am trying to run some code that has 'import websocket' however I am getting the error: ModuleNotFoundError: No module named 'websocket'
I have Python 3.7.3 and I am running in Spyder (if that makes a difference).
So from other questions/answers I found on here, in my cmd I ran pip install websocket and then also pip install websocket-client when the first one didn't run.
I am still getting the ModuleNotFoundError. Does it matter the location/folder of the code or where I install the pip command in cmd?
My python code starts with these import statements:
import json
import websocket
import traceback
import helper
import ssl
import time as time
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import griddata
from mpl_toolkits.mplot3d import Axes3D
In cmd I ran:
C:\Users\myname>pip install websocket
and also:
C:\Users\myname>pip install websocket-client
The error I am getting is:
File "C:/Users/micki/Downloads/Derbit-Volatility-Visulization-master/Derbit-Volatility-Visulization-master/Volatility Surface Class.py", line 2, in <module>
import websocket
ModuleNotFoundError: No module named 'websocket'
Not sure, as you did not cover how you installed and are using Spyder, though I think it is probably an issue with your environment. You might also find that you are missing the module "helper" as well. There's two easy options as follows:
If you installed and are using Spyder via conda or anaconda, follow their documentation on installing websocket-client to the correct environment found here.
The second option (the preferred option IMHO, as you can use any IDE or text editor going forward), regardless of how you installed Spyder, would be to create a python virtual environment python3 -m venv /path/to/new/virtual/environment, pip install all your dependencies in said environment, then link Spyder's interpreter to the interpereter that was installed when you made the environment. In Spyder, go to Tools -> Preferences -> Python interpreter -> check the "Use the following Python interpreter:" radio button and enter the path to the interpreter from the environment you just created. For reference, see docs on making and using a python venv here.
If the websocket and websocket-client doesn't work, try:
pip install websocket_client
This solved my issue:
sudo pip install websocket-client
I installed python 3.7 on my pc (win 10). Later I tried to install matplotlib using a pip command, it installed and matplotlib is now also inside the pip list. When I go to the lib/site-packages folder where I saved python, it clearly has matplotlib inside of it. matplolib also works when us it in my command promt after using the 'python' command. But when I wanna import it in my project in pycharm, it does not work and no module is found.
I am new to all this and this is the first module I installed for python, so I can not figure out what I am doing wrong here. The version of matplotlib I am trying to install is 2.2.3.
Thx for any help
I need to use netcdf but do not have install permission for python modules. I have downloaded netcdf-0.1.2.tar.gz from here: https://pypi.python.org/simple/netcdf/ and unzipped the tar ball. I have been following this stack overflow post in an attempt to use the module but have had no luck so far:
(Python) Use a library locally instead of installing it
here is what I have tried:
Installing virtualenv:
I do not have permission to do this
python setup.py install -- user:
again, I don't have permission
running my script with netcdf as my current working directory:
I tried this as well, here are the issues I have run into:
first I went into netcdf-0.1.2 and made a new file called asdf.py
which contains the following:
import netcdf
print("testing")
running python asdf.py gives the following error:
Traceback (most recent call last):
File "asdf.py", line 1, in <module>
import netcdf
File "/.../Downloads/netcdf-0.1.2/netcdf/__init__.py", line 1, in <module>
from netcdf import *
File "/.../Downloads/netcdf-0.1.2/netcdf/netcdf.py", line 1, in <module>
from netCDF4 import Dataset, numpy
ImportError: No module named netCDF4
I'm not sure how to fix this error, any help would be greatly appreciated
in case this is somehow relevant, the version of Linux I am using is 3.2.0-23-generic
also I have numpy installed already
Easest would be to install Anaconda or Miniconda with your user rights.
Anaconda already as netCDF4installed. In case of Miniconda install with:
conda install netcdf4
If you have Python 3 installed, then you will have the venv package in the standard library, so you do not need "virtualenv" to be installed for you separately (as would be the case with Python 2). Instead use python3 -mvenv , in a similar way to how you would use virtualenv, for example:
python3 -mvenv /path/to/my_venv
or to include any non-standard packages already installed on the system:
python3 -mvenv --system-site-packages /path/to/my_venv
After that, you should be able to activate the environment and pip install packages, e.g.
source /path/to/my_venv/bin/activate # for csh use activate.csh instead
pip install netCDF4
Remember to source the activate script at run time as well as installation time:
source /path/to/my_venv/bin/activate
python
and you should then find that in your python session you have the netCDF4 package available, e.g.
import netCDF4
my_dataset = netCDF4.Dataset('myfile.nc')
Of course, substitute the actual path in place of /path/to/my_venv above.
None of this requires any root privileges.
(And as someone else has suggested, another option for you is to use conda.)
I'd also like to highlight that the package is imported using capitals
import netCDF4 as nc
This might not matter on a mac, but for Windows it is key.
I have installed Anaconda (version 1.6.2) installed on my 64 bit machine. It comes with a great set of libraries, but I also need Basemap, part of matlibplot, but it is not included with the Anaconda install. I attempted to install Basemap and move the files in the Anacaonda\Lib\site-packages\mpl_toolkits directory since it is part of the mpl_toolkits library. However when I attempt to run a script, I keep getting the errors:
"No module named _geoslib"
"Cannot import pyproj"
I found the pyproj library. Do I need it? Where can I find geoslib? And how do I get Basemap to work?
What you nees is to change your path first, by:
$ export PATH=~/anaconda/bin:$PATH
and then,
$ conda install basemap
( I assumed you are in Linux)
source:http://docs.continuum.io/anaconda/faq.html
If your on Windows try installing Basemap from the Sourceforge executable, these should include GEOS and PROJ4 dependencies of Basemap.
I believe all that is needed is to update matplotlib, I just had this problem and doing this worked for me:
pip install --upgrade matplotlib
