I was happy to find out that pyomo was already pre-installed on colaboratory .
Unfortunately, the solver I need is not installed.
I tried to install it, but it did work.
(using conda install ipopt_bin -c cachemeorg)
Any idea how to install ipop on colaboratory ?
Thanks
Try this installation command:
conda install -c conda-forge ipopt
Try This :
!apt install coinor-libipopt-dev
And then this:
!pip install ipopt

Can someone provide the steps and the necessary links of the dependencies to install external python package "opencv-python" for image processing?
I tried installing it in pycharm, but it was not able to import cv2(opencv) and was throwing version mismatch with numpy!
Please help!
The good thing with anaconda is that it should make your life easier without getting your hands too dirty. If you use only basic libs, only install packages with anaconda commands to be sure not to corrupt your python environment.
if you're on linux, use conda install -c conda-forge opencv
on windows, do the same with the "anaconda prompt" terminal.
If you still have some trouble with you numpy version, try conda update numpy
Create a virtual env. Following which run following instals
pip install numpy scipy matplotlib scikit-learn jupyter
pip install opencv-contrib-python
pip install dlib
You may verify the install via this script in Python environment-
import cv2
cv2.version
Remove all previous/current (if any) python installation
Install Anaconda and add anaconda to PATH(Envirnoment variables:: Adavanced system setting->Environment variables->under system variables go to variable PATHand click edit to add new envirnomental variables)
(During installation check box involve PATH)
Open anaconda prompt with admin access. Type and enter:-
conda update --all
conda install -c conda-forge opencv
conda install spyder=4.0.0 (spyder updation)
conda update python (for python updation)
To install this package with conda run one of the following:
conda install -c conda-forge opencv
conda install -c conda-forge/label/gcc7 opencv
conda install -c conda-forge/label/broken opencv
conda install -c conda-forge/label/cf201901 opencv
I tried to run a program in python3.4, but it always give me this error message
from skimage import feature
ImportError: No module named 'skimage'
I search the internet for answers here and there, tried some solutions, but i keep getting the error. But then I tried to run the exact same program in python2.7, and it did not give any error mesaage so I assume that it runs well in python2.7. Is there anyway I can get this program running in python3.4?
You have it installed in your Python 2 libraries. You should install it in your Python 3 libraries too:
$ pip3 install scikit-image
I had the same problem, I have the scikit-image package installed in Python 3 and when I ran:
$ ./<filename.py>
I got the same error. Turns out Python 2 was running. Try running:
$ python3 ./<filename.py>
If you have installed python via Anaconda, you can run the following. It fixed the error.
conda install --yes -c conda-forge scikit-image
I tried every possible method within the environment but failed terribly until I used sudo.
What did work:
sudo pip install scikit-image
What didn't work
pip install scikit-image
conda install scikit-image
conda install -c anaconda scikit-image
conda install --yes -c conda-forge scikit-image
pip3 install scikit-image
I have tried many approaches in resolving this issue but still cannot resolve it can someone please help me.
when I try to run the pip to install any new package it is ending in error with the message no module named packaging.version. This is happening in the __init__.py file where there are import command import packaging.version.
I tried to install the packaging package by using the command pip install packaging even that ended in failure with the same error.
Then I tried to install this package using the apt-get command
sudo apt-get install python-packaging but it ended saying could not find the package.
Finally I tried to update the setuptools package to version 33.1.1 as a part of the previous solutions approaches, but can't do it with pip(same issue as above) so I used the apt-get command
sudo apt-get install setuptools=33.1.1 but it is saying no package with this version found error.
I am out of ideas can someone please help. Appreciate your help.
I believe that your version of pip is obsolete. Try running pip install --upgrade pip.
If you cant do it (still the same error), I'd suggest to reinstall pip.
You can do it with get-pip.py file. Here you can find a quick guide: Installing pip setuptools and wheel.
You may also be able to reinstall it with python -m pip install -U pip.
I've just learned how to use virtualenv and I installed Django 1.4.5. I'm assuming that the virtualenv created a clean slate for me to work on so with the Django 1.4.5 installed, I copied all my previous files into the virtualenv environment.
I tried to run the server but I get an error saying "no module named MySQLdb". I think this means that I forgot to install MySQL-python. I tried to install it via
pip install MySQL-python
But I get this error

Not quite sure how to go about fixing this problem =/ any help much appreciated!
I recently had exactly this issue (just not in relation to Django). In my case I am developing on Ubuntu 12.04 using the default pip and distribute versions, which are basically a little out of date for MySQL-python.
Because you are working in an isolated virtualenv, you can safely follow the suggested instruction without affecting your Python installation.
So you can...
workon your_virtualenv #activate your virtualenv, you do use virtualenvwrapper, right?
easy_install -U distribute #update distribute on your virtualenv
pip install MySQL-python #install your package
If for some reason upgrading distribute is not an option, you could try installing an older version of MySQL-python as follows (you'd have to check this version is compatible with your version of Django):
pip install MySQL-python==x.y.z #where x.y.z is the version you want
Spent an hour looking through stackoverflow. Evntually found answer in the other question. This is what saved me:
sudo apt-get install libmysqlclient-dev
mysql_config goes with the package.
When doing in a virtualenv :
pip install MySQL-python
I got
EnvironmentError: mysql_config not found
To install mysql_config, as Artem Fedosov said, first install
sudo apt-get install libmysqlclient-dev
then everything works fine in virtualenv
MySQL driver for Python (mysql-python) needs libmysqlclient-dev. You can get it with:
sudo apt-get update
sudo apt-get install libmysqlclient-dev
If python-dev is not installed, you may have to install it too:
sudo apt-get install python-dev
Now you can install MySQL driver:
pip install mysql-python
Here is a more detailed documentation for MySQL in Django:
http://codex.themedelta.com/how-to-install-django-with-mysql-in-a-virtualenv-on-linux/
I had to do this:
pip install mysql-python
inside the virtualenv
The commands are always run in ubuntu:
easy_install -U distribute
later
sudo apt-get install libmysqlclient-dev
and finally
pip install MySQL-python
The suggested solutions didn't work out for me, because I still got compilation errors after running
`$ sudo apt-get install libmysqlclient-dev`
so I had to run
apt-get install python-dev
Then everything worked fine for me with
apt-get install python-dev
Try this:
Version Python 2.7
MySQL-python package, you should use either MySQL_python‑1.2.5‑cp27‑none‑win32.whl or
MySQL_python‑1.2.5‑cp27‑none‑win_amd64.whl depending on whether you have installed 32-bit or 64-bit Python.
pip install MySQL_python‑1.2.5‑cp27‑none‑win32.whl
if you are using mysqlclient package, then use
mysqlclient‑1.4.6‑cp27‑cp27m‑win32.whl or
mysqlclient‑1.4.6‑cp27‑cp27m‑win_amd64.whl
pip install mysqlclient‑1.4.6‑cp27‑cp27m‑win32.whl

Docutils is a great package. If you are using Django the admindocs package needs docutils. Instructions are available for installing with a web browser, but what if you are remote and logging in with a terminal over SSH? How to install in that case? What if you just want a quick recipe to do the job with the terminal?
I know I'm rather late to this question, but the accepted answer doesn't really reflect the common best practices from Python community members (and even less so from the Django community members.) While the outlined manual installation process does work, is is far more pains taking and error prone than the following:
You really should be using Pip. With Pip installing docutils system wide is as simple as:
$ sudo pip install docutils
This not only works for docutils but nearly any package on the 'Cheese Shop' as well as many other code repositories (Github, Bitbucket, etc.)
You may also want to look into other common Python best practice tools like virtualenv and virtualenvwrapper so that you can avoid global package installation.
To install Pip on Ubuntu/Debain I generally do the following:
$ sudo apt-get install python-pip
BTW: for virtualenv 'sudo apt-get install python-virtualenv' and for virtualenvwrapper 'sudo apt-get install virtualenvwrapper'.
The key to the install is to use the curl utility. The following will install docutils:
mkdir docutilsetup
cd docutilsetup
curl -o docutils-docutils.tar.gz http://docutils.svn.sourceforge.net/viewvc/docutils/trunk/docutils/?view=tar
gunzip docutils-docutils.tar.gz
tar -xf docutils-docutils.tar
cd docutils
sudo python setup.py install
This performs the following steps: Create a directory to download docutils into. cd into the directory just made, and use curl to download the zipped version of docutils. Unzip the file which creates a subdirectory docutils. cd into that directory and install with root permissions.
If you are using Django you will have to restart Django for admindocs to start working.
Although it is an old thread, I want to share the answer I found. To install type command
sudo apt install python-docutils
or
sudo apt install python3-docutils
This will install the dependencies too. Yesterday, I installed docutils using this command for Geany editor and it is working fine.
