Anaconda software can't find packages installed with pip on Windows - python

On Windows, open up Anaconda Prompt and type in the following:
pip install json2xml
No complaints from pip for doing this (replace json2xml with your favorite package, I guess). Then, open up Jupyter QTConsole, and try:
import json2xml
The result is an ImportError: No module named 'json2xml'. The package installed (after checking pip list), but nothing recognizes it. There is no system pip (this is Windows, after all); only Anaconda's pip is being used.
What's going on?

I hope this will help, it worked for me.
When you use pip to install a package, by default it will go to your python site-packages.
i. e.
C:\Users\YOUR-USER-NAME\AppData\Local\Programs\Python\Python37-32\Lib\site-packages
From here, you can copy the downloaded packages, then navigate and paste them into your Anaconda site-packages directory.
i. e.
C:\Anaconda\Lib\site-packages
That should solve the issue.

From How do I find the location of my Python site-packages directory? , you can enter
python -m site
to print your python package location(s). In my case, I have Anaconda for Windows and do not have a directory C:\Users\YOUR-USER-NAME\AppData\Local\Programs\Python\Python37-32\Lib\site-packages but did find my package installed with pip was in C:\Users\YOUR-USER-NAME\AppData\Local\Continuum\anaconda3\Lib\site-packages\ . This may be due to adding Anaconda to PATH.

Python module not found after installing anaconda

Hope everyone is doing fine :)
I'm new to python, so I'm having trouble cause I've installed anaconda (for machine learning) and now, my local projects in VS Code with python, don't find modules installed from pip install.
I've searched online and I guess it has something to do with the path... Here's the path when I install the module:
user_stuff.../opt/anaconda3/lib/python3.9/site-packages
I want to install modules into my project on desktop, here's the path:
user_stuff.../Desktop/python-project
I keep getting this error when trying to import:
ModuleNotFoundError: No module named 'qrcode'
How do I change this? It's really frustrating :(
I guess your pip is referring to the pip provided by the system, it should be now referring to the pip provided by anaconda.
$ which pip
$ alias pip="/Users/my-username/anaconda3/bin/pip"
$ pip install qrcode
Do you use jupyter notebook in vs code? I prefer it because there you can easily select the environment you are using. And if you want to pip install anything in a environment you have to first activate it in the console with conda activate env name

PIP install package - installed but python is not importing

Running on Windows 10, I have Python 3.7.3 installed to my c/users/myUser/appdata/local/programs folder.
When I use PIP to install a package, it seems to run fine, but when I use "import package" in python it doesn't recognize that package. What would cause this?
Running 'python --version' works and also running 'pip --version' works.
PIP shows up in my c/users/myUser/appdata/local/programs/python37-32/lib/site-packages/pip folder.
UPDATE:
So I was looking through files to determine where the libraries are located that do work with my python. The folder is located in Python/Python37-32/Lib. All of those currently work when importing. However when I do anything with PIP it does not add anything to that folder.
I noticed there are a couple different PIP executables within Python/Python37-32/Scripts which include pip.exe, pip3.exe, and pip3.7.exe. I tried using "pip3.7 install numpy" which also did not work.
I noticed when trying to add an existing package its pointing to the Python37-32/lib/site-packages folder.
SOLUTION:
I removed python from my machine, and reinstalled it. I had the same problem. What I done to fix this was to use
PS
python -m pip install --user package
Also I appended my PATH environment variable with
cmd
setx path "%path%;C:\Users\MyUser\AppData\Roaming\Python\Python38\Scripts"
That seemed to have taken care of my issue. Now when I install a package with PIP I can reference it through python.

install taichi package on python

I tried to run a script with python, it has taichi package downloaded from GitHub.
I have little knowledge of how python packages are installed, now I got error in command prompt like
"ModuleNotFoundError: No module named 'taichi'"
I just installed package downloaded from GitHub: https://pypi.org/project/taichi/#files
Hope someone can teach what should I do to run my script contains taichi package~
To install packages in python you just run the command pip install (name of package) in the command prompt so in your case that would be pip install taichi
How to install virtualenv:
Install pip first
sudo apt-get install python3-pip
Then install virtualenv using pip3
sudo pip3 install virtualenv
Now create a virtual environment
virtualenv venv
Active your virtual environment:
source venv/bin/activate
Now install your package for python
pip3 install taichi
I have figured it our that this Taichi package needs 64 bits python, it also needs LLMV file downloaded. Besides, there should be virtual studio installed in the local computer.
Then this Taichi package can be installed just by using "pip install taichi" in command.
Thanks for everyone's help!
I alse encountered this problem,I confirmed that I have already successfully installed taichi whereas it still showed "no module named taichi" .And here is my solution:tryimport sysandsys.path to check whether the file of the packages is contained in python's search range.
For example,after I inputsys.path in python ,it shows ['e:\\', 'd:\\anaconda2022\\python39.zip', 'd:\\anaconda2022\\DLLs', 'd:\\anaconda2022\\lib', 'd:\\anaconda2022', '', 'd:\\anaconda2022\\lib\\site-packages', 'd:\\anaconda2022\\lib\\site-packages\\win32', 'd:\\anaconda2022\\lib\\site-packages\\win32\\lib', 'd:\\anaconda2022\\lib\\site-packages\\Pythonwin']
I am using anaconda as the python interpreter in vscode ,so the packages of taichi is installed in d:\\anaconda2022\\lib\\site-packages,and I can import it successfully . But previously my sys.path are incorrectly setted to E:\\Python but not D:\\anaconda2022. Python cannot find the packages of taichi from the wrong sys.path.
Check the sys.path in python may help.If it is the one which cause the problem , there are many ways to edit sys.path .I solved it by uninstalling the python for I installed python and anaconda at the same time (- -).

ModuleNotFoundError, but it runs in anaconda (jupyter)

I've installed a module named rauth through terminal with pip3 install rauth command but when I import the module and run the code on Visual Studio Code with python3 interpreter, it gives ModuleNotFoundError: No module named 'rauth' error. But it is indeed installed and I can use it in Anaconda. The package file is stored here.
/Users/puffedricecracker/anaconda3/lib/python3.7/site-packages/rauth
And it seems like all my pip installed packages are stored in that path, but those are imported outside Anaconda with no problem. Tried several other commands as google search suggested.
• pip install instead of pip3 install
• python -m pip install
• python3 -m pip install
Let me know if there is any other information needed to be specified.
this is due to the module is installed into site-packages in Anaconda but not Visual Studio. Can you check if the module exists in Visual Studio folder? Another way to test it is to open Python IDLE and run the import, it should also return an error.
I don't know if this could be an universal solution but there was a way to set where to install a package using pip.
In python shell, find where your python modules usually go. It seemed like most of pip installed packages were installed in the second path so I chose that.
>>> import re
>>> print(re.__file__)
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/re.py
>>> import sqlalchemy
>>> print(sqlalchemy.__file__)
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/sqlalchemy/__init__.py
Uninstall the package using pip uninstall packagename
Reinstall with a path name.
pip install packagename -t /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages
(In fact, just copy pasting package files (in my case, they were rauth, rauth-0.7.3.dist-info) from anaconda package path in the post worked.)

How to install win32com module in a virtualenv?

I have installed both virtualenv and pywin32 on my Windows 7 64-bit laptop, and each of them seems to work, but not with each other.
More specifically, if a virtualenv is active, then running import win32com.client in a python interactive shell fails with No module named win32com.client. The same expression succeeds, however, if no virtualenv is active.
When I try to install pywin32 with pip (which is how I normally install modules when a virtualenv is active), I get the error:
Could not find any downloads that satisfy the requirement pywin32
No distributions at all found for pywin32
...even though pywin32 is one of the modules listed in the output of
pip search pywin32
Therefore, to install pywin32 at all I had to install it using an *.exe installer downloaded from SourceForge.
Is there any way to install pywin32 within a virtualenv?
UPDATE 2016
There is now a version of pywin32 on PyPI that can be installed with pip. It is called pypiwin32, and it installs the package using the binary wheel format.
https://pypi.python.org/pypi/pypiwin32
pip install pypiwin32
That will work in a virtualenv, or with tox, etc.
Below this line is my previous old answer. That is now outdated information.
OLD ANSWER - OUTDATED. Modern versions of virtualenv default to --no-site-packages. That means that not having access to global site-packages is now the default behavior.
Sadly, (as of July 2014) you can not pip install pywin32 in to your virtualenv. (here's the bug report)
If you want to get pywin32 running inside a virtualenv, activate the virtualenv and use easy_install and the pywin32 installer exe file. For example
easy_install "C:\Path\To\Downloads\pywin32-219.win32-py3.4.exe"

Try this:
Download directly
Enable your virtualenv
pip install --no-index --find-links:/local/dir/ SomePackage
Check out #8 on pip-installer.org (sorry no permalink)/
Create a virtualenv and activate it:
cd c:\Users\ernesto.luzon
virtualenv --no-site-packages py351env
py351env\Scripts\activate
From here, you have two options:
Download pywin32 from sourceforge project:
http://sourceforge.net/projects/pywin32/files/pywin32/
Download pywin32 from unofficial (but very helpful) binary site:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#pywin32
Make sure you download the correct version for the Python Interpreter installed in your environment, otherwise you will encounter ImportError: DLL load failed: %1 is not a valid Win32 application later.
If you downloaded from sourceforge, install it using easy_install:
(py351env) C:\Users\ernesto.luzon\Downloads>easy_install pywin32-220.win-amd64-py3.5.exe
If you downloaded from gohlke, install it using pip:
(py351env) C:\Users\ernesto.luzon\Downloads>pip install pywin32-220-cp35-none-win_amd64.whl
In case you encounter ImportError: DLL load failed: The specified module could not be found error later on, you need these additional steps:
Run the post install script:
(py351env) C:\Users\ernesto.luzon>python py351env\Scripts\pywin32_postinstall.py -install
Copied pythoncom35.dll to C:\Users\ernesto.luzon\py351env\pythoncom35.dll
Copied pywintypes35.dll to C:\Users\ernesto.luzon\py351env\pywintypes35.dll
....
Notice where it copied the 'pythoncom35.dll' and 'pywintypes35.dll' files. You need to move these files to the folder:
C:\Users\ernesto.luzon\py351env\Lib\site-packages\win32
