first post here, so I'm going to try to be as thorough as possible.
I'm trying to install numpy/matplotlib/pandas for a project. First time trying to use them. I'm following the steps of a tutorial, so I can't vary from that too much (have to use anaconda). I'm using mac OS Sierra 10.12.5
What I've done:
installed python 3, anaconda, and create and initialize a virtual environment using Anaconda. I then type:
conda install numpy pandas matplotlib
The terminal then tells me what new packages will be installed, I proceed. A few are installed successfully, and then I get this error:
CondaError: CondaHTTPError: HTTP None None for url https://repo.continuum.io/pkgs/free/osx-64/mkl-2017.0.3-0.tar.bz2
Elapsed: None
An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
I thought this might be a connection issue, as I'm in China, but I've tried multiple times both using and not using a VPN. This problem is really stopping me in my tracks, any ideas?
Have you tried using the pip installer, or installing using the Anaconda navigator? To install using pip, after creating the virtual environment, open a terminal console, and type
source activate [name of virtual environment]
pip install numpy
pip install matplotlib
pip install pandas
Pip is included in the base anaconda installation, so this should work. If your Anaconda installation included the Anaconda Navigator, you can also install these modules through the GUI, by opening the Anaconda Navigator, clicking on the environments tab, selecting the virtual environment, searching for module in the search bar (make sure you select All and not Installed in the dropdown menu next to it), and then selecting the desired modules and clicking the apply button (this is an example).

I am running WSL2 under Windows 10.
If I type "gedit &" into the WSL console, the Gedit application window pops up. Thus I assume that WSLg properly works.
Next, I am trying to run the following PyQt5 project:
https://github.com/rafaelpadilla/review_object_detection_metrics
However, no application window pops up this time, although no error message appears either.
First of all, I do wonder whether this could work at all with WSL!?
Appendix for additional context:
I am not using conda because of licensing issues, but a combination of pyenv + poetry instead. First I had problems with a missing library (libxcb.so), which I could solve by running "sudo apt python-pyqt5". Now everything seems to work, except from no application window being shown.
UPDATE:
I tried with "/src/pyqt-official/qtdemo/qtdemo.py" from the official PyQt Examples github repository and I observed exactly the same issue.
There is no error message. Last prompt informs me that the "xcb plugin was loaded“, then nothing happens. In particular, no window is showing up.
Some related observations:
(1) I haven't yet updated my grafics card driver to support vGPUs. However, Gedit works and opens in a separate window.
(2) Unless I do "sudo apt install python3-pyqt", I receive an error message saying that it cannot find "libxcb.so". However, I am running the code in a virtual pyenv/poetry environment, which is separate from the system python installation. I don't understand why "sudo apt install python3-pyqt" makes a difference here. Shouldn't installing "PyQt5" with poetry obtain a wheel that comes with all libraries already compiled? I don't understand how all of this is playing together.
Open Questions:
Do you think the driver issue could be an explanation? I actually cannot imagine that. I thought it is only about better performance for OpenGL applications.
Can you explain observation (2)?
What else can I do?
First of all, I do wonder whether this could work at all with WSL!?
I can't tell you if that particular application will run under WSL, but my expectation is that it will. As far as I can tell in its dependencies there doesn't seem to be any reliance on GPU compute. That, to me, would be the trickiest part to configure under WSL (but is still typically possible). However, there may be other dependencies (not covered below) that you need to get running before the application can work.
What I can confirm is that PyQt works under WSL just fine. However, keep in mind that a default Ubuntu installation under WSL is based on a non-GUI Ubuntu Server distribution, rather than standard Ubuntu (with a desktop and GUI).
This means that Ubuntu Server is often missing system level libraries needed for GUI support, which appears to be the case here.
I don't understand why "sudo apt install python3-pyqt" makes a difference here. Shouldn't installing "PyQt5" with poetry obtain a wheel that comes with all libraries already compiled?
Poetry and/or Pip manage the Python library dependencies, but those Python libraries still require the native system library dependencies. That's where sudo apt install python3-pyqt5 comes in. Under a desktop Ubuntu system, most of these libraries would already be in place. However, with Ubuntu Server/WSL, they aren't.
For reference, here's my configuration. On a freshly initialized Ubuntu 22.04 WSL2 distribution:
sudo apt update && sudo apt upgrade -y
sudo apt install python3-venv python3-pyqt5
mkdir -p src/pyqt_test
cd src/pyqt_test
python3 -m venv .venv
source .venv/bin/activate
pip install pyqt5
I was then able to create and run the following, taken from Learn Python PyQt:
import sys
from PyQt5 import QtWidgets
app = QtWidgets.QApplication(sys.argv)
windows = QtWidgets.QWidget()
windows.resize(500,500)
windows.move(100,100)
windows.show()
sys.exit(app.exec_())
The window displayed correctly.
I've been trying to use the packages pandas, numpy, matplotlib, seaborn in my "Visual Studio Code", but the program keeps showing me the following message:
"import pandas could not be resolved from source Pylance(reportMissingModuleSource)"
Previously to Visual Studio Code I installed "Anaconda" to use Jupyter, and now it says that i have the existing packages (pandas, numpy...) but keeps appearing this message that doesn't allow me to use pandas in my Visual Studio.
Anyone could help me to solve this issue?
I tried installing again all the packages to check if they didn't exist but apparently are installed all of them but in another route. I can't find how is the way to put them so the Visual Studio Code recognizes them and I can use them.
I also received similar an error on my IDE VSCode and currently using mac m1 .First we need to make sure that the python3 interpreter version from terminal version is the same with our python version selection in VSCode.
open terminal.
type 'python3'
then you will see your python version.(my python3 version is 3.9.12)
python3 version
open your IDE VSCode
open any/current folder that related to python project on IDE VSCode
Check your python version at the bottom right on IDE VSCode (in my case the python version is 3.10.64)
change or switch VSCode python version from 3.10.64 to 3.9.12 (same with your python version on your pc)
done
I also had this problem and it was because of version mismatches.
I had installed Python AND Anaconda. If anyone else has done this and gets this error, you need to uninstall both. Then install Anaconda only; Python (the compatible version) is installed as part of that process.
See https://docs.anaconda.com/anaconda/install/windows/
Also, you can click on the interpreter version at the bottom left corner of the screen (Vs.code 2022) it should show a dropdown menu with a list of the available and selected python interpreter. Click on add interpreter path and paste the path to the python interpreter with all the required modules installed and click enter. This should resolve the problem.
I re-entered the path to Python interpreter and warning disappeared. Hope that helps you.
Another way I solved this issue having followed every other installation process to the letter was deactivating Pylance. Works a (py)charm now.
I encountered this problem in VSCode under remote to WSL2 of Windows 10. The Python version is correct as interpreter (3.9.13) and the terminal in VSCode is also under the same envs (ie. VSCode ran "conda activate xx" and (xx) is shown in prompt)
Originally, I tried to install the pandas by the following command.
sudo apt-get install python3-pandas
Pandas was installed successfully as stated in the terminal but the problem is still there.
When I try to install pandas by the following command, the problem solved.
pip install pandas
I followed the instructions on the official website to download the TensorFlow. I chose to create a virtual environment as the instruction shown for macOS. My question is that if I need to activate the virtual environment each time before I use TensorFlow?
For example, I want to use tensor flow on Jupiter notebook and that means I need to install Jupiter and other required packages like Seaborn/pandas as well on the virtual environment. However I already downloaded anaconda and basically, it has all the packages I need.
Besides, will it make a difference if I download it with conda?
Well, if you downloaded the packages (like you said TensorFlow and Seaborn) in the base Conda environment which is the default environment that anaconda provides on installation, then to use what it has, you need to run whatever program/IDE like Jupyter lab from it. So you would open Anaconda Prompt and then type in jupyter lab and it would open up a new socket and you can edit with your installed python libraries from Conda.
Otherwise in IDE's VSCode you can simply set the python interpreter to that from Conda.
However, if you install the libraries and packages you need using pip on your actual python installation not Conda, then there is no need for any activation. Everything will run right out of the box. You don't need to select the interpreter in IDE's like VSCode.
Bottom line, if you know what libraries you need and don't mind running pip install package-name every time you need a package, stick with pip.
If you don't like to that sort of 'low level' stuff then use Anaconda or Miniconda.
Mine is Anaconda 5.3.0
When I run .py in PyCharm 2018.2.4, why it shows that:
ImportError:
DLL load failed: The specified module could not be found.
ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: DLL load failed: The specified module could not be found.
It seems that PyCharm 2018.2.4 cannot import numpy??
Does anyone see this problem too? How to fix it? Thank you very much.
You can set the Python interpreter path on PyCharm to the Anaconda one (something like ~/anaconda3/bin/python).
Todo do so, open the Settings dialog >> Project: [ProjName] in the left panel >> Project Interpreter. Now you can add to the list paths to local Python interpreters, or virtual environments in the project folder or in a folder specified in the WORKON_HOME.
More instructions here and here.
I believe I have useful information if not the solution.
I too received the error using python to import numpy from the windows command prompt. Then I realized I could succeed if I used the Anaconda prompt. Curious about the difference, I exited python and examined the PATH environment variable. As I had hoped, it contained Anaconda references that did not exist in the Windows PATH. At the command prompt I typed: path > p.txt and hit enter to create a file since the string was so long. When I opened the file in notepad I copied the Anaconda references to the clipboard (C:\Users\laptop\Anaconda3;C:\Users\laptop\Anaconda3\Library\mingw-w64\bin;C:\Users\laptop\Anaconda3\Library\usr\bin;C:\Users\laptop\Anaconda3\Library\bin;C:\Users\laptop\Anaconda3\Scripts;C:\Users\laptop\Anaconda3\bin;) then used the Advanced Settings under the System Control Panel to Edit the Environment Variable and paste it on the beginning of PATH. The problem seems to have gone away, both in the Windows shell and in Pycharm.
First, try to delete .git file from project folder and re-enable vcs. Then uninstall numpy by:
pip3 uninstall numpy
After that, go to pycharm and open File > settings > Project Intepreter get the python location url ex: usr/bin/python3. Copy that path and open terminal and type:
usr/bin/python3 install numpy. Wait for pycharm indexing and try to run project again
I don't think it's an issue with PyCharm.
I got Anaconda 5.3 today and use PyCharm Pro 2018.2.4. Unfortunately, I got the same error as you do. However, if you go to powershell (if you are on Windows like me), type in python and import numpy you still got the same error.
Not sure why yet but uninstall & reinstall didn't help (and tbh I don't get why this might help in any sense though).
So my current solution is:
Roll back to Anaconda 5.2 with Python 3.6 and everything gets back to working.
I have the same thing, pychrm 2018.2 & Anaconda3 (64-bit) 5.3 on win10
I think the issue is about Anaconda, I have uninstalled the Anaconda 5.3 and installed Anaconda 5.2, then everything is ok
I have installed NumPy using pip install and it's working fine while using it in the python interpreter on the command line. But whenever I try
import numpy in PyCharm it throws an error module not found.
I already set the right path in the project interpretor and the import numpy command is working fine with other IDEs such as Syder or Jupyter notebook but it doesn't work in PyCharm.
I found a YouTube video that worked for me in importing a package into PyCharm. First, click on the File menu, then click on Settings, then click on Project Interpreter. Look for a + sign to the right and click on that. That allows you to add a package. Then search for your package of choice (I wanted numpy) in the Search bar at the top. Click on the name, and then at the bottom click on Install Package. After a few minutes, it will say, package successfully installed, and sure enough it was. I was able to import numpy the usual way in PyCharm.
Did you install official Python or Anaconda/Miniconda?
I assume PyCharm created either a virtualenv or a conda env, or an isolated Python environment that does not have NumPy installed.
You should either use your global environment instead of virtualenv:
Settings, Project: project-name / Project Interpreter, https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html
Or install NumPy in your virtualenv or conda env.
This is more complicated. If you open Terminal in PyCharm and it says (project-name) in your prompt, try pip install numpy.
