How to install OpenCV 3.4.5 in Ubuntu 14.04?

I am trying to install OpenCV 3.4.5 in Ubuntu 14.04 LTS and I need this OS for my project. I have not found any proper way to do so. I tried this: https://docs.opencv.org/3.4.5/d2/de6/tutorial_py_setup_in_ubuntu.html but cannot install the dependencies as mentioned.
Any suggestions or guide would be much appreciated.
Assuming you have Python installed, try install opencv-python which is an unofficial pre-built OpenCV package.
pip install numpy
pip install opencv-python==3.4.5
To ensure successful installation, open IDLE to check version number:
import cv2
print(cv2.__version__)

"Could not find a version that satisfies the requirement opencv-python"

I am struggling with Jetson TX2 board (aarch64).
I need to install python wrapper for OpenCV.
I can do:
$ sudo apt-get install python-opencv
But I cannot do:
$ sudo pip install opencv-python
Is this because there is no proper wheel file in http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv?
Is there a way to install opencv-python through pip?
We were getting the same error.For us, it solved by upgrading pip version (also discussed in FAQ of OpenCV GitHub). Earlier we had pip-7.1.0, post upgrading it to "pip-9.0.2", it successfully installed.
pip install --upgrade pip
pip install opencv-python
pip doesn't use http://www.lfd.uci.edu/~gohlke/pythonlibs/, it downloads packages from PyPI.
The problem is that you have an unusual architecture; pip cannot find a package for it and there is no source code package.
Unfortunately I think you're on your own. You have to download source code from https://github.com/skvark/opencv-python, install compiler and necessary libraries and compile OpenCV yourself.
Use this and it will work:
pip install --upgrade pip
pip install opencv-python
Another problem can be that the python version you are using is not yet supported by opencv-python.
E.g. as of right now there is no opencv-python for python 3.8. You would need to downgrade your python to 3.7.5 for now.
It happened with me on Windows, pip was not able to install opencv-python==3.4.0.12.
Later found out that it was due to the Python version, Python 3.7 has some issue with not getting linked to https://github.com/skvark/opencv-python.
Downgraded to Python 3.6 and it worked with:
pip3 install opencv-python
I faced the same issue but the mistake which I was making was pip install python-opencv where I should have used pip install opencv-python. Hope this helps to anyone. It took me few hours to find.
As there is no proper wheel file in http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv?
Try this:(Worked in Anaconda Prompt or Pycharm)
pip install opencv-contrib-python
pip install opencv-python
A way to do this is to install Anaconda on your computer.
Then you should be able to do:
pip install opencv-python
or
conda install opencv
I had the same error. The first time I used the 32-bit version of python but my computer is 64-bit. I then reinstalled the 64-bit version and succeeded.
Install it by using this command:
pip install opencv-contrib-python
I faced same issue while using Python 3.9.0.
Upgrading python to latest version (currently 3.9.1) and reinstalling opencv-python solved this issue.
I got this error and I solved it by simply waiting.
I had similar problem:
ERROR: Could not find a version that satisfies the requirement opencv-contrib-python (from versions: none)
Command pip update was not resolving my issue.
After lunch-time I tried again and it installed correctly the package.
Maybe the server was down.
I update the version of python, and then the issue was addressed. Please refer to this video: https://www.youtube.com/watch?v=BQnpRbbEZB4

Install td-agent (treasure data fluentd) on ubuntu 16.04

From http://docs.fluentd.org/v0.12/articles/install-by-deb, I can only find the instructions to install td-agent 2.3.5 where as I need to install td-agent 2.3.4 as there are some plugins which I needed tested only on 2.3.4.
I looked at the sources list /etc/apt/sources.list.d/treasure-data.list and also https://td-agent-package-browser.herokuapp.com/2/ubuntu/, but couldn't figure out how to get this version installed.
Can you please someone help on how to install td-agent 2.3.4?
Found the packages at https://td-agent-package-browser.herokuapp.com/2/ubuntu/trusty/pool/contrib/t/td-agent
and could able to install the old version with these instructions
sudo dpkg -i /tmp/td-agent_2.3.4-0_amd64.deb
sudo apt-get install -f

Problems installing scikit-image in ubuntu 14.04

When I try to install scikit-image with pip2 there is show error. I have tried to find this problem solution.
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/scikit-image
Storing debug log for failure in /home/nshakib/.pip/pip.log
My guess is that you might have missing dependencies. I don't think Ubuntu 14.04 comes out of the box with any of the SciPy stack.
To answer your question try,
sudo apt-get install python-matplotlib python-numpy python-pil python-scipy
Then
sudo apt-get install build-essential cython
Finally
sudo apt-get install python-skimage
If that still doesn't work, you could try using the Anaconda Distribution for Python 2.7 from Continuum Analytics.
It comes with many of the major packages built-in and has a great package manager that manages dependencies.
https://docs.continuum.io/anaconda/install#anaconda-install
The conda package would be installed with conda install scikit-image

Installing OpenCV in Python3.3

I'm trying to install OpenCV in python 3.3.2 and Ubuntu 12.04. I've followed this tutorial
Install opencv for Python 3.3
but I can't seem to make it work. When I try to 'import cv2' it says there is no module with that name
Any help with this issue? Thanks.
In ubuntu, you can type command:
sudo apt-get install python-opencv
which will provide you compatible version of opencv to your python.
I had the same problem in windows. But then I copied cv.pyd from opencv/build/python/2.7/x86 instead of opencv/build/python/2.7/x64. It works if you do so. I hope it would be helpful.
