Setup:
Windows 7
Docker v1.6.0, installed as part of Boot2docker
Docker-compose v1.2.0
I installed docker-compose using pip:
pip install docker-compose
And it seemed to install successfully. However, when I try to run: docker-compose up in the directory in which I have my docker-compose.yml definition, I get the following exception:
Traceback (most recent call last):

import fcntl
ImportError: No module named fcntl
I understand from different posts unrelated to docker that this error is thrown because fcntl is linux native and, obviously, my python windows distribution is missing it. However, the workarounds the people there specified don't necessarily apply to my personal case.
I also tried the steps here: https://github.com/docker/compose/releases
I downloaded the linux archive using curl (had no uname resolution) and gave execution right, but still:
$ docker-compose -version
./docker-compose: ./docker-compose: cannot execute binary file
Is anyone aware of any workarounds / actually functional ways of installing docker-compose on a Boot2docker VM?
You can run docker compose on boot2docker Windows.
You can install docker compose in a container directly in boot2docker and use it that way.
See "How to install docker-compose on Windows and issue 1085.

I am aware that very similar questions have been asked previously but I have found these have tended to include Docker, which I am not using at this time, nor do I have installed. I am led to believe that WSL2 should be an alternative to Docker regarding running Airflow on Windows.
I am using WSL2 on my Windows 11 laptop and have installed Apache-Airflow from a tutorial from the following link:
https://coding-stream-of-consciousness.com/2018/11/06/apache-airflow-windows-10-install-ubuntu/
On WSL2 I have:
Python version 3.8.10
Pip version 20.0.2
Apache-Airflow 2.4.1 (I believe)
I have run the following commands (as per the tutorial) with no issue:
sudo apt-get install software-properties-common
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install python-pip
sudo pip install apache-airflow #I had path issues without 'sudo' command
But when I attempt to use the 'airflow' command in the WSL2 Ubuntu terminal, I am greeted with the following error:
$ airflow
Unable to load the config, contains a configuration error.

raise ValueError('Unable to configure handler '
ValueError: Unable to configure handler 'processor'
I have googled the ValueError extensively and can't find any clear solutions that don't involve Docker.
Any insight into the error would be much appreciated!
You should install airflow using constraints.
https://airflow.apache.org/docs/apache-airflow/stable/installation/installing-from-pypi.html#installation-tools
This is the only way installation of airflow is guaranteed to work.
Wanted to make run my Python Flask project via Heroku (it's the first time I am using it). The case is, that I connect to a remote MariaDB on a Ubuntu VM.
When I try to push from local git I get an error to be related to the MariaDB. Is there an idea how I can solve this problem?

It looks like you need the mariadb_config utility at compile time. This is likely because whatever Python driver you are using requires it.
mariadb_config is available in the libmariadb-dev Ubuntu package. You'll need to install that using the Apt buildpack.
Add the buildpack:
heroku buildpacks:add --index 1 heroku-community/apt
That buildpack doesn't do dependency resolution, so you'll have to list all transitive dependencies.
Create a new file called Aptfile (no extension) that lists the dependencies you wish to install:
mysql-common
mariadb-common
libmariadb3
libmariadb-dev
Commit your Aptfile and redeploy.
I'm getting the following error trying to run ipython3.
catch_config_error() missing 1 required positional argument: 'app'
I first got it on my Mac (python36). As my system has all sorts of customizations, I tried it again on a Linux system (Centos 7.4). I install ipython using pip3 and everything seemed to install cleanly. (On the same system, if i do this with python2, it seems to work.
Complete error log:

This is happening because traitlets relies on a package called 'decorator' that was just updated from 4.1.2 to 4.2.0 and broken its backward compatibility.
If you're using a requirements file or pip, install decorator==4.1.2 before installing IPython.
I tried in Ubuntu 16.04.
I also had the same problem (Python 3.6)
I tried again today.
$ sudo -H pip3 install --upgrade ipython
Then, decorator 4.2.1 is newly installed and the problem is solved.

Someone has suggested that I should completely remove zmq and reinstall it.
I have tried to do it with pip but it seems that in some config files remain. I have used locate and I manually removed some directories. I thought that it would help but after reinstallation still I have an error. I am using Python2.7 and Ubuntu 14.04.
You can try the following:
sudo rm /usr/local/lib/libzmq*
sudo rm /usr/local/include/zmq.h
Since these are the two locations that ZeroMQ's libzmq installs into.
This link provides a few options on how to uninstall zeromq if you use a Debian operating system.
You would need to use the purge command:
sudo apt-get purge --auto-remove python-zmq
You probably installed it using the source ditribution.
To undo this, cd to the build directory and type:
make uninstall
I have recently installed SimpleCV on Windows 10 from the superpack. Everything went well during the installation, and I was able to successfully run the first example problem in "Practical Computer Vision with SimpleCV" (good book, btw) from within IDLE. Here's the code:
from SimpleCV import Camera, Display, Image
cam = Camera()
display = Display()
img = cam.getImage()
img.save(display)
Simple enough, and it worked fine. Where I ran into problems was when I tried to start up the SimpleCV console. First of all, no link was created on the Windows desktop, and there was nothing for SimpleCV on the Start menu. So, I tried the other methods listed in the book. First, from the console, I tried to run it as a Python module:
C:\User> python -m SimpleCV.init
And what I got back was:
ERROR:
Traceback (most recent call last):

raise(e)
ImportError: No module named IPython
Next, I tried the listed alternative: just starting python and importing and executing the Shell. Entering:
>>> from SimpleCV import Shell
resulted in the same error as above.
I also tried installing ipython by running pip. But, it looks like pip didn't get installed either.
So, what environmental variable did the installation program not set correctly? Just so you know, I posted this same question on the SimpleCV site, but have not received a response as of yet.
--- 23 Dec 2015
Chipping away at this. Read the banner on setuputils install. Ran Python27\Scripts\easy_install.exe. Can now call pip. However, entering this at the command line:
C:\Users> pip install ipython
gives this error:
C:\Python27\lib\site--packages\pip-7.1.2-py2.7.egg\pip\_vendor\requests\packages\urllib3\util\ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cuase certain SSL connections to fail. For more information, see...
So, I'm making progress. Any suggestions?
Have you tried to install ipython from source code?
$ tar -xzf ipython.tar.gz
$ cd ipython
$ python setup.py install
See https://ipython.org/ipython-doc/3/install/install.html
There are a lot of requirements more. I recommend the SimpleCV's github repository instructions https://github.com/sightmachine/SimpleCV#windows-8
