Install python 3.6 in Ubuntu - pip

I'm running some Python script in my bitbucket pipeline.
where it's running in Ubuntu version 16.04.
following is my script.
add-apt-repository ppa:deadsnakes/ppa -y && apt-get update
apt-get -y install python3.6
apt-get -y install python3-pip
pip3 install tq1
pip3 install zstd
When trying to print
python3 -V
it's returning
Python 3.5.2.
Why it's not Python 3.6.x ?
Please note I must need Python 3.6 to run tq1.

It's a script on your device, right? Can't you just edit the lines?
sudo add-apt-repository ppa:deadsnakes/ppa -y
sudo apt-get update
sudo apt-get -y install python3.6 python3-pip
pip3 install tq1 zstd
Also, you don't need a script to install those. They're just bash commands. You can just type them line-by-line into the terminal...

Check the image on your pipeline, because if you install python 3.6 in one step and execute the python3 -V command in another, it will take the version of the image, not the one from the previous step, since they are in a different container, it would be helpful if you show us the rest of the pipeline

How can I install ruby 2.7.2 (Dockerfile) in Ubuntu 18.04?

I am creating a Dockerfile and somehow I can't install the ruby version I need: 2.7.2 . Since I just need this version, I don't want to install ruby through rbenv or rvm. I tried "apt install ruby", "apt get install ruby 2.7.2", "apt install ruby-full" and the version installed is always 2.5.1. Any Ideas?
This is how my Dockerfile looks like:
FROM nvidia/cuda:10.1-base-ubuntu18.04
LABEL version="0.0.1"
LABEL maintainer="mjg"
RUN apt update \
&& apt install -y python3.6 python3-pip \
&& apt install -y ruby
WORKDIR /cvlib
RUN pip3 install --upgrade pip; \
pip3 install opencv-python tensorflow cvlib; \
apt install -y libsm6 libxext6 libxrender-dev libgl1-mesa-glx; \
apt remove -y python3-pip
WORKDIR /app
COPY . .
VOLUME [ "/app/blurred-images", "app/source-images" ]
Using apt install ruby will install ruby version from distribution repository, which in your case in ruby 2.5.1. You should consider installing it with ruby version managers like rbenv or rvm, because they allow you to specify specific version that you want to install.

Installation of Rstudio for ubuntu

I want to install Rstudio for ubuntu, so I used the link https://www.rstudio.com/products/rstudio/download/ after that I choosen RStudio 0.99.893 - Ubuntu 12.04+/Debian 8+ (64-bit) then I opened with Ubuntu software center. In that I clicked the install button I got error box like this,
Requires installation of untrusted packages
This requires installing packages from unauthenticated sources.
How to solve this problem?
The unauthenticated package required by RStudio is libjpeg62, so install the package separately and then install rstudio from software center
In the terminal run the following for installing libjpeg62
sudo apt-get install --allow-unauthenticated libjpeg62
Then go back to installing rstudio.
Note: you need to install r interpretor along with rstudio this you can do by following
sudo apt-get install r-base
# Install R and RStudio on Ubuntu 14.04
sudo apt-get update
sudo apt-get install r-base
sudo apt-get install r-base-dev
# Download and Install RStudio
sudo apt-get install gdebi-core
wget https://download1.rstudio.org/rstudio-1.0.44-amd64.deb
sudo gdebi rstudio-1.0.44-amd64.deb
Runs following commands :
In order to install RStudio on Ubuntu 18.04 we will first need to install the r-base package. Open up terminal and enter:
$ sudo apt update
$ sudo apt -y install r-base
To install DEB file on Ubuntu Linux is by using the gdebi command.
In case gdebi is not available on your system you can install it by executing the bellow command:
$ sudo apt install gdebi-core
All Package(builds) are available : in this link or link. You can select different package.
I had download and install : rstudio-xenial-1.1.463-amd64.deb build(package) from above in this link.
$ wget https://s3.amazonaws.com/rstudio-dailybuilds/rstudio-xenial-1.1.463-amd64.deb
$ sudo gdebi rstudio-xenial-1.1.463-amd64.deb
To Start R-Studdio from following command :
$ rstudio

How to install pip in CentOS 7?

CentOS 7 EPEL now includes Python 3.4: yum install python34
However, when I try that, even though Python 3.4 installs successfully, it doesn't appear to install pip. Which is weird, because pip should be included by default with Python 3.4. which pip3 doesn't find anything, nor does which pip.
How do I access pip from the Python 3.4 package in CentOS 7 EPEL release?
The easiest way I've found to install pip3 (for python3.x packages) on CentOS 7 is:
$ sudo yum install python34-setuptools
$ sudo easy_install-3.4 pip
You'll need to have the EPEL repository enabled before hand, of course.
You should now be able to run commands like the following to install packages for python3.x:
$ pip3 install foo
curl https://bootstrap.pypa.io/get-pip.py | python3.4
Or if you don't have curl for some reason:
wget https://bootstrap.pypa.io/get-pip.py
python3.4 get-pip.py
After this you should be able to run
$ pip3
The CentOS 7 yum package for python34 does include the ensurepip module, but for some reason is missing the setuptools and pip files that should be a part of that module. To fix, download the latest wheels from PyPI into the module's _bundled directory (/lib64/python3.4/ensurepip/_bundled/):
setuptools-18.4-py2.py3-none-any.whl
pip-7.1.2-py2.py3-none-any.whl
then edit __init__.py to match the downloaded versions:
_SETUPTOOLS_VERSION = "18.4"
_PIP_VERSION = "7.1.2"
after which python3.4 -m ensurepip works as intended. Ensurepip is invoked automatically every time you create a virtual environment, for example:
pyvenv-3.4 py3
source py3/bin/activate
Hopefully RH will fix the broken Python3.4 yum package so that manual patching isn't needed.
Update: The python34 bug mentioned below has finally been fixed. It is a perfectly fine choice now.
Rather than using broken EPEL python34 packages, you can enable the IUS repo and have it work properly.
pip inside virtual environments
The main python34u and python35u IUS packages include the pyvenv tool (/usr/bin/pyvenv-3.4 or /usr/bin/pyvenv-3.5) that includes bundled wheels of pip and setuptools for bootstrapping virtual environments.
global pip
The python34u-pip and python35u-pip IUS packages include /usr/bin/pip3.4 and /usr/bin/pip3.5 respectively. These work just fine to install packages to the system site-packages directory.
yum install python34-pip
pip3.4 install foo
You will likely need the EPEL repositories installed:
yum install -y epel-release
Update 2019
I tried easy_install at first but it doesn't install packages in a clean and intuitive way. Also when it comes time to remove packages it left a lot of artifacts that needed to be cleaned up.
sudo yum install epel-release
sudo yum install python34-pip
pip install package
Was the solution that worked for me, it installs "pip3" as pip on the system. It also uses standard rpm structure so it clean in its removal. I am not sure what process you would need to take if you want both python2 and python3 package manager on your system.
Below are the steps I followed to install python34 and pip
yum update -y
yum -y install yum-utils
yum -y groupinstall development
yum -y install https://centos7.iuscommunity.org/ius-release.rpm
yum makecache
yum -y install python34u python34u-pip
python3.6 -v
echo "alias python=/usr/bin/python3.4" >> ~/.bash_profile
source ~/.bash_profile
pip3 install --upgrade pip
# if yum install python34u-pip doesnt work, try
curl https://bootstrap.pypa.io/get-pip.py | python
There is a easy way of doing this by just using easy_install (A Setuptools to package python librarie).
Assumption.
Before doing this check whether you have python installed into your Centos machine (at least 2.x).
Steps to install pip.
So lets do install easy_install,
sudo yum install python-setuptools python-setuptools-devel
Now lets do pip with easy_install,
sudo easy_install pip
That's Great. Now you have pip :)
Figure out what version of python3 you have installed:
yum search pip
and then install the best match. Use reqoquery to find name of resulting pip3.e.g
repoquery -l python36u-pip
tells me to use pip3.6 instead of pip3
On CentOS 7, the pip version is pip3.4 and is located here:
/usr/local/bin/pip3.4

dpkg is installed in root filesystem of my target, i have checked it using whereis command
Please suggest, or can you suggest some link for installing apt-get itself. I am not able to find something related to it.
Any reply will be appreciable.
Looks like maybe debian apt package will get you there. I thought apt was just ubuntu but no.
The Raspbian FAQ is here: http://www.raspbian.org/RaspbianFAQ
In it you can grab a list of apps included in Rasbian:

You can grab the Raspbian package archive here:
http://archive.raspbian.org/raspbian/dists/wheezy/main/binary-armhf/Packages.gz
Extract it, then use dpkg to install apt-get.
Install Putty.exe and login with putty to your raspbian with ip-adress of your raspbian and you can install apt-get!
