Getting the following error after running pip install airflow[postgres] command:
> raise RuntimeError("By default one of Airflow's dependencies installs

I am trying to install in Debian 9
Try the following:
export AIRFLOW_GPL_UNIDECODE=yes
OR
export SLUGIFY_USES_TEXT_UNIDECODE=yes
Using export makes the environment variable available to all the subprocesses.
Also, make sure you are using pip install apache-airflow[postgres] and not pip install airflow[postgres]
Which should you use: if using AIRFLOW_GPL_UNIDECODE, airflow will install a dependency that is under GPL license, which means you won't be able to distribute your resulting application commercially. If that's a problem for you, go for SLUGIFY_USES_TEXT_UNIDECODE.
If you are installing using sudo run one of these commands:
sudo AIRFLOW_GPL_UNIDECODE=yes pip3 install apache-airflow
OR
sudo SLUGIFY_USES_TEXT_UNIDECODE=yes pip3 install apache-airflow
NOTE: If pip3 (python3) does not work for you, try pip command.
The pip command can be pointing to python2 or python3 installation depending on your system. Verify this by running pip --version.
Windows users can use the command below before installing apache-airflow:
$ set AIRFLOW_GPL_UNIDECODE=yes
then
$ pip install apache-airflow
In case you are installing the airflow on Windows and through Python terminal then you need to write this:
Set SLUGIFY_USES_TEXT_UNIDECODE=yes
pip install apache-airflow[postgres]
It worked with me after I struggled with trying many other options. Hope this will work with you too.
Below command should install apache-airflow and lets you pull changes into PyCharm for building DAGs and coding for Airflow.
SLUGIFY_USES_TEXT_UNIDECODE=yes
pip install apache-airflow
Also, if you are installing using sudo you can use:
export AIRFLOW_GPL_UNIDECODE='yes'
sudo -E pip3 install apache-airflow
(or use SLUGIFY_USES_TEXT_UNIDECODE)
Run the following command in your python terminal: SLUGIFY_USES_TEXT_UNIDECODE=yes pip install apache-airflow==1.10.0
Use below command to install apache-airflow
sudo SLUGIFY_USES_TEXT_UNIDECODE=yes \
pip install apache-airflow[async,devel,celery,crypto,druid,gcp_api,jdbc,hdfs,hive,kerberos,ldap,password,postgres,qds,rabbitmq,s3,samba,slack]

While installing LabelImg in M1 Mac using below command
pip install pyqt5 lxml
This is the error I got
ERROR: pyqt5 from https://files.pythonhosted.org/packages/7c/5b/e760ec4f868cb77cee45b4554bf15d3fe6972176e89c4e3faac941213694/PyQt5-5.14.0.tar.gz#sha256=0145a6b7de15756366decb736c349a0cb510d706c83fda5b8cd9e0557bc1da72 has a pyproject.toml file that does not comply with PEP 518: 'build-system.requires' contains an invalid requirement: 'sip >=5.0.1 <6'
How to install lableImg annotation tool in M1 Mac?
I got it to work by using the following commands
brew install pyqt#5
pip install labelimg
And that's it, it just works
You just need to type labelimg in the Terminal and the app will start running
I don't know why they don't tell you this in the installation guide
Alrighty!
On MacOS Monterey, none of the other solutions posted here solved this problem for me. However, I managed to easily solve the issue, without a virtual environment or too much fiddling about like so:
Firstly, you have to download all labelImg packages from this link:
https://github.com/tzutalin/labelImg#macos
(You can download it as a .zip file or clone it)
Unzip and then in your terminal cd into whatever directory you downloaded the above files to.
Then run the following commands in order:
pyrcc5 -o libs/resources.py resources.qrc
Then,
pip3 install lxml
Finally,
python3 labelImg.py
It should run without an issue now.
You can go one of two ways:
Using brew:
You can use homebrew to install the dependencies - like qt and libxml2. This will let your package manager handle everything and generally should solve the problem with the . Then you can run
python3 labelimg.py
Using Virtual Environments:
This is the more recommended way to go about in such cases. You can use conda, pipenv or venv to create a virtual environment which is isolated from your system python installation. Then you can try to install it as explained in the README.rst in the root of the repository:
brew install python3
pip3 install pipenv
pipenv run pip install pyqt5==5.12.1 lxml
pipenv run make qt5py3
pipenv run python3 labelImg.py
[Optional] rm -rf build dist; python setup.py py2app -A;mv "dist/labelImg.app" /Applications
You can try the two methods and and get back with the errors if there are any.
This is my note.
I just succeed on my Mac M1 Chip
CHECK THIS OUT!

Python 3.6.9
I presume you are a Linux user. I faced a similar issue when I was trying to install Python
3.9 but when I ran python -V in the terminal, it would tell me I had version 2.
I can't guarantee
this will work but it worked for me. If you are using Ubuntu 20.04 a Linux distro, by default you have Python 3.9. In Ubuntu 18 and 16 there is also a Python version pre-installed. In your case, you need to first uninstall Python 3.
Using this command in the terminal.
sudo apt-get remove --purge python3
After uninstalling, reinstall as Python 3.9 version using this command:
sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.9
python3.9 --version
Again if you're using an editor like Pycharm your base interpreter will be messed up! So please be careful when uninstalling.
And this code works on Ubuntu which I presume is what you are working on.
Another thing you need to install a repository to get Py 3.9. it's called deadsnakes I've mentioned the code above on how you could install it.
I hope you faced no issues. Remember it worked for me but I'm not sure it will work for you. Enjoy with Python 3.9 if the installation is successful :)
For whatever reason, Amazon moved R to the so-called "Extras Library" so you can't install R using sudo yum install -y R anymore. Instead, you have to do sudo amazon-linux-extras install R3.4. As a result, I can only install R 3.4.3 when the newest stable release is 3.6.1, and so many R libraries can't even be installed because the version is too low. Is there any good and clean way to install the latest version of R and skip Amazon's package manager? Thanks!
Use amazon-linux-extras which installs R4.0.2:
amazon-linux-extras install R4
You may need root:
sudo amazon-linux-extras install R4
I've tried setting up R 3.6.x on a docker container that uses the amazonlinux image. My approach was to get the R source file from the below link and install from source
cd /tmp/
wget https://cloud.r-project.org/src/base/R-3/R-3.6.3.tar.gz
tar -zxf R-3.6.3.tar.gz
cd /tmp/R-3.6.3
./configure --without-libtiff --without-lapack --without-ICU --disable-R-profiling --disable-nls
make
make install
you will need to yum install some dependencies, like 'make', which doesn't seem to come with aws amazonlinux docker image (which i think mirrors the EC2 instance AMI image you are referring to).
The above kind of worked for me in that i had a working R3.6 installation, but it didnt allow me use it with rshiny server, so i'm reverting to the shipped 3.4.3 version.
tl;dr: you'll probably have to manually download the source files and install the desired R version from source, and throw in some build dependencies as well.
Try this on Amazon Linux 2
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install R
Amazon Linux 2 Image contains extras library that can be used as well. Follow the guide here.
https://aws.amazon.com/premiumsupport/knowledge-center/ec2-install-extras-library-software/
sudo amazon-linux-extras enable R3.4
sudo yum clean metadata && sudo yum install R3.4
I'm trying to uninstall all django packages in my superuser environment to ensure that all my webapp dependencies are installed to my virtualenv.
sudo su
sudo pip freeze | grep -E '^django-' | xargs pip -q uninstall
But pip wants to confirm every package uninstall, and there doesn't seem to be a -y option for pip. Is there a better way to uninstall a batch of python modules? Is rm -rf .../site-packages/ a proper way to go? Is there an easy_install alternative?
Alternatively, would it be better to force pip to install all dependencies to the virtualenv rather than relying on the system python modules to meet those dependencies, e.g. pip --upgrade install, but forcing even equally old versions to be installed to override any system modules. I tried activating my virtualenv and then pip install --upgrade -r requirements.txt and that does seem to install the dependencies, even those existing in my system path, but I can't be sure if that's because my system modules were old. And man pip doesn't seem to guarantee this behavior (i.e. installing the same version of a package that already exists in the system site-packages).
starting with pip version 7.1.2 you can run pip uninstall -y <python package(s)>
pip uninstall -y package1 package2 package3
or from file
pip uninstall -y -r requirements.txt
Pip does NOT include a --yes option (as of pip version 1.3.1).
WORKAROUND: pipe yes to it!
$ sudo ls # enter pw so not prompted again
$ /usr/bin/yes | sudo pip uninstall pymongo
If you want to uninstall every package from requirements.txt,
pip uninstall -y -r requirements.txt
on www.saturncloud.io, Jupiter notebooks one can use like this:
!yes | pip uninstall tensorflow
!yes | pip uninstall gast
!yes | pip uninstall tensorflow-probability
Alternatively, would it be better to force pip to install all dependencies to the virtualenv rather than relying on the system python modules to meet those dependencies,
Yes. Don't mess too much with the inbuilt system installed packages. Many of the system packages, particularly in OS X (even the debian and the derived varieties) depend too much on them.
pip --upgrade install, but forcing even equally old versions to be installed to override any system modules.
It should not be a big deal if there are a few more packages installed within the venv that are already there in the system package, particularly if they are of different version. Thats the whole point of virtualenv.
I tried activating my virtualenv and then pip install --upgrade -r requirements.txt and that does seem to install the dependencies, even those existing in my system path, but I can't be sure if that's because my system modules were old. And man pip doesn't seem to guarantee this behavior (i.e. installing the same version of a package that already exists in the system site-packages).
No, it doesn't install the packages already there in the main installation unless you have used the --no-site-packages flag to create it, or the required and present versions are different..
Lakshman Prasad was right, pip --upgrade and/or virtualenv --no-site-packages is the way to go. Uninstalling the system-wide python modules is bad.
The --upgrade option to pip does install required modules in the virtual env, even if they already exist in the system environment, and even if the required version or latest available version is the same as the system version.
pip --upgrade install
And, using the --no-site-packages option when creating the virtual environment ensures that missing dependencies can't possibly be masked by the presence of missing modules in the system path. This helps expose problems during migration of a module from one package to another, e.g. pinax.apps.groups -> django-groups, especially when the problem is with load templatetags statements in django which search all available modules for templatetags directories and the tag definitions within.

I am new to redis and I am installing redis cli, using the below tutorial.
https://www.digitalocean.com/community/tutorials/how-to-install-and-use-redis
this tutorial suggests to do sudo make install after make test, but when I am doing "sudo make install", it give me the below prompt
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
I do not have any idea whether this will create any problem in installing the cli globally.
Any suggestions on this will be a great help.
You can alternatively copy the server and cli application by doing:
sudo cp src/redis-server /usr/local/bin/
sudo cp src/redis-cli /usr/local/bin/
as described in the Redis documentation.
