I'm trying to port a python application to jython and have run into a problem where jython cannot import kombu (which is used prominently in the original python app).
I have installed kombu via pip (and even tried the -U option to get the most recent version):
sudo pip install -U kombu

I have jython version 2.5.3 installed and when I try to import kombu, I get an "ImportError: No module named kombu" error:
Jython 2.5.3 (2.5:c56500f08d34+, Aug 13 2012, 14:48:36)

ImportError: No module named kombu
>>> from kombu.connection import BrokerConnection

ImportError: No module named kombu
Any help would be greatly appreciated!
Thanks,
Flint
With help from the folks on the Jython IRC, I finally got past this error. My problem was that I wasn't installing kombu within Jython. The process to accomplish that can be found at Importing python modules in jython.

After installing cupy via "pip install cupy-cuda110", I tried this in python3:
import cupy as cp

Failed to import CuPy.
If you installed CuPy via wheels (cupy-cudaXXX or cupy-rocm-X-X), make sure that the package matches with the version of CUDA or ROCm installed.
On Linux, you may need to set LD_LIBRARY_PATH environment variable depending on how you installed CUDA/ROCm.
On Windows, try setting CUDA_PATH environment variable.
Check the Installation Guide for details:
https://docs.cupy.dev/en/latest/install.html
Original error:

"
May you know how to resolve this problem? Many thanks!
Before installing cupy, you should check the version of Cuda that is installed on your device :
!nvcc --version
For me, the Cuda version installed on my device is 11.0 (See the picture below) :
After that go to the official Cupy website https://docs.cupy.dev/en/stable/install.html
The following image is from the page I referred to above:
Then type the install command that matches your Cuda version, for me, the install command will be :
pip install cupy-cuda110
When installing these packages with CUDA 11.2, 11.3, or 11.4, you may experience a “Failed to import CuPy” error. To resolve this error, please uninstall cupy-cuda115 and install cupy-cuda11x:
pip uninstall cupy-cuda115
pip install cupy-cuda11x

I've installed it using:

Any help on this?
That can be specific for a programming platform you are using. Some platforms like PyCharm enable to install modules directly from themselves so using modules becomes much easier.
I have installed Selenium.When i try to run the tests it complains of ImportError: No module named 'selenium'.
The OS is Ubuntu 14.04 LTS and python version 3.4 (via virtualenv).

Don't use sudo to install selenium into your virtual environment:

This is a known bug that has been fixed (https://github.com/matplotlib/matplotlib/pull/3414) on master.
The bug is in the handling of searching for a freetype installation. If you install the Linux package freetype-dev, you will avoid this bug and be able to compile matplotlib.
sudo apt-get install libfreetype6-dev
On Ubuntu 14 server, you also need to install libxft-dev
sudo apt-get install libfreetype6-dev libxft-dev
I had the same issues trying to install matplotlib on Python 3 using pip3, and it seems that this problem is related to a bare-bones installation of Python 3, and doing a:
sudo apt-get build-dep matplotlib
followed by
sudo pip3 install matplotlib
is probably a better solution than selectively installing only the libraries related to matplotlib.
Since mac doesn't have apt-get you, on OSX you may need to do:
brew install freetype
then you can run:
pip install matplotlib
Found this page while looking answer for fedora 24.
RPM solution is:
dnf install freetype-devel
If you re running Ubuntu server 14.04 u should add this font dependency
sudo apt-get install libxft-dev
Source
I was trying too update directly using sudo pip but changes are not saved in last. So i first use update cmd in terminal:
sudo apt-get update
then i used sudo install:
sudo apt-get install libffi-dev
Finally its installed by doing this method.
For those on Fedora 25 hitting this thread, I needed these two packages to make it work:
sudo dnf install freetype-devel gcc-c++
This worked for me:
python -m pip install -U pip setuptools
python -m pip install matplotlib

Recently, I performed a clean install of OS X Mountain Lion and restored my system from a Time Machine backup. When I tried to use python, it was unable to find most of the modules that I had installed before I wiped my OS. It also appears that the Xcode Command Line Tools were no longer on the system.
I reinstalled the Xcode Command Line Tools and pip (using easy_install), and went to work reinstalling the modules I use, starting with numpy. However, pip said it was already installed:
Requirement already satisfied (use --upgrade to upgrade): numpy in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
However, in the CLI for Python, it still can't find numpy:
Python 2.7.3 (v2.7.3:70274d53c1dd, Apr 9 2012, 20:52:43)

I've tried to install some other modules. When I installed ujson with pip, everything went fine, and python found it with no problems. However, when I tried to install matplotlib with pip, clang threw an error and it failed to install. I think the problem might be that matplotlib has dependency on numpy, but I don't know.
In file included from src/ft2font.cpp:3:
src/ft2font.h:16:10: fatal error: 'ft2build.h' file not found

Any advice on how to resolve this issue? Should I just uninstall this other version of numpy, or do you think this is a deeper issue?
Deleting the numpy files in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python and reinstalling numpy would be my suggestion. It seems like the libraries are no longer being linked to properly even though the files are there.
