I am trying to install a package called 'numpy'.
i have python setup in eclipse luna with the help of pydev.
how do i install numpy in pydev.
tried putting numpy in site-packages folder. doesnt seem to work
In Eclipse, Goto Windows->Preferences
Select PyDev->Interpreters->Python Interpreters
Then click on Manage with pip button, then you will see a new window like below, you just need to type your package and click Run/Press enter.
After this, Click Apply and OK, then Right click on Project then click on PyDev->Remove error markers.
Hope it works.
do you have pip installed with your python?
How to install pip
Then if you have your path variable set you can simply type "pip install numpy" into command line.
download the required version of numpy from here http://sourceforge.net/projects/numpy/files/NumPy/1.9.2/
and the install directly ,it will run on eclipse automatically
If it does not solve your purpose use Pip:
pip install numpy
Correct way is to create a virtualenv virtualenv ~/venvs/eclipse, install numpy (source ~/venv/eclipse/bin/activate;pip install numpy), then add the virtualenv to eclipse (see https://www.rose-hulman.edu/class/csse/resources/Eclipse/eclipse-python-configuration.htm)
Pandas can be installed after install python in to your pc.
to install pandas go to command prompt and type "pip install pandas" this command collecting packages related to pandas. After if it asking to upgrade pip or if pip is not recognized by the command prompt use this command:
python -m pip install --upgrade pip.

When I try to install opencv-python I get the following error:
ModuleNotFoundError: No module named 'cv2'
I tried to install cv2 via these commands:
pip install opencv-python
pip install opencv-contrib-python
pip install opencv-python opencv-python-headless
python3 -m pip install opencv-python
pip3 install opencv-python --upgrade
However, the problem remains.
I have noticed that this problem occurs only in the virtual environment (venv) of VScode.
In fact, if I launch this code from the terminal it does not give me any error and it returns me the version of cv2
import cv2
print (cv2.__version__)
Reply -> 4.6.0
I use Python 3.9
EDIT:
This is a screenshot of the problem
The problem do not appear if I create a new venv
Use Ctrl+Shift+P to open the command palette search and select Python:Select Interpreter, then select the correct interpreter, this will solve your problem.
Tip: Every time you choose a new interpreter, please create a new terminal to activate the environment.
As far as your question is concerned, you can follow these steps:
Select the interpreter in the virtual environment according to the above method
Create a new terminal
Use pip install opencv-python to install the package
Also you can use pip show opencv-python to see where the package is installed.
What solved it for me was adding the following to the .vscode/settings.json config file
// Add venv to python path
"python.analysis.extraPaths": [
"${workspaceFolder}/venv/lib/python3.8/site-packages"
]
change venv to the name of your virtual env folder.
I wanna install OpenCV module in GUI if it is possible.
But as following pictures, the search result doesn't show opencv-python and opencv-contrib-python modules.
Why this problem happens?
There is just no such a package in repositories used by conda package manager.
Running conda install opencv-python from the system terminal will fail for the same reason.
You can install it with pip though.
Click the following button to use pip instead of conda package manager and try again:
I am attempting to update pip for IDLE (Python 3.5) on mac using the terminal.
It tells me that pip is up to date in anaconda:
Daniels-MacBook-Pro-3:~ danielsellers$ pip install --upgrade pip
Requirement already up-to-date: pip in ./anaconda/lib/python3.6/site-packages
Daniels-MacBook-Pro-3:~ danielsellers$
But IDLE is recommending I update pip, which I am inclined to do because it keeps crashing while trying to install modules.
How do I update the version of pip which IDLE is running? I'm somewhat new to python, thanks in advance
If you use Anaconda you are fine, if you don't uninstall it. Systems get very confused on what you want to update/use so just pick one and use it!
I don't know commands of MAC but concept should be like this:
from terminal change directory to your Python3.5 interpreter and then go in folder called Scripts. For example:
cd C:\Python35\Scripts
Then update your pip from there like:
pip install --upgrade pip
EDIT:
In PyCharm IDLE it is in File/Settings/Project:'project_name'/Project Interpreter. In other IDLEs should be similar.
I am a beginner in programming with Python. I have installed Python 3.6.1, and when I try to install pip (or any other package), this error appears (both in the command and shell):
install pip
^
SyntaxError: invalid syntax
I tried also with pip -m pip, but nothing, still the same error.
I would be very grateful if you could help me.
To install a Python package, you need to be in the command line as #MohideenibnMohammed suggested. You cannot install a package from within a Python script using pip.
You have installed Python 3.6.1 which will have pip already installed so you don't need to try and install that again.
Next, you need to make sure that Python is added to your PATH.
Open Start Menu and right click My Computer. Click on Advanced System Settings.
Click on Environment Variables
Find the system PATH variable and click Edit. You want to add Python to this PATH variable by adding exactly ;C:\Python36 (assuming that is where you installed Python)
Go back to the command line and type in pip install numpy (you can use pip3 instead of pip if you wish)
I think you are trying to use pip command in python console instead of terminal.
or check your command again .. pip install package
otherwise try this,
use pip3 install package to install instead of pip install package
I'm trying to install the wxPython package using Pycharm's Project Interpreter on my mac. I have been able to install other packages in the past, but with this package I get an error:
Any ideas? I've checked, and I have both read and write permissions to both the ./pip and ./pip/http directories, and pip is up to date.
Try using homebrew instead.
Once brew is installed, just type 'brew install wxpython' in your terminal to install wxPython.
