I am creating a face recognition system using Python and OpenCV on these versions:
Python 3.6.2 (64-bit)
OpenCV 3.3.0
When I try to train the face recognizer:
face_recognizer = cv2.face.createLBPHFaceRecognizer()
and also I tried
face_recognizer = cv2.createLBPHFaceRecognizer()
It gave me attribute error
AttributeError: module 'cv2.cv2' has no attribute 'createLBPHFaceRecognizer'
When I tried
pip install opencv-python
I got these errors
Exception:

I'd been facing the same issue recently. Here's a list of things that went wrong:
You need to uninstall opencv before installing opencv-contrib
Make sure no console is running that has imported cv2 while you execute your installing process
Run the cmd in Administration Mode (Go to the .exe of the cmd program, right click and select 'Run as Administrator')
This should work.
Hope this helps!
In case of windows, in cmd try to run pip install using python executable
python -m pip install opencv-python
if you're using linux, you just have to give it superuser permission:
sudo -s
pip install opencv-python
note: do not use "su" because it does not recognize the "pip" command
You can use the below command i.e add user to the command
pip install --user opencv-contrib-python

I am unable to install packages in my intel dev cloud. I tried installing packages using pip from bash shell. I also created a new conda environment and tried installing packages there. It didn't work either. I think the problem is with permissions in file system. The error says "read-only file system" as you can see.
Any suggestions can greatly help.
P.S: I am trying to install keras and sklearn
please check the error log below.

Yes, you correctly diagnosed the problem.
You need to choose a writable filesystem to write the installed files to.
You may find the df and mount commands helpful. Start with man df.
With the guidance of #J_H I found out the answer.
pip usually tries to install packages globally, which is not allowed on shared platforms like Intel DevCloud. Hence we need to install packages for single user that is you.
Hence
pip install --user keras
installs keras in your home directory and you are not restricted to write in your home directory. Problem Solved!
I'm getting unexpected arg: keyword encoding in parse() while trying to install any python package through pip.
I'm getting this problem since i installed tensorflow for python 3.6, which probably led to some issue with html5lib and setuptools. Have reinstalled html5lib1.0b10 using tar.gz file (admin install) but the issue still remains.
Please help!!

Issue was indeed with html5lib and setuptools, I re-installed html5lib using
conda install -c anaconda html5lib
Although package versions were same, it said 'The following packages will be SUPERSEDED by a higher-priority channel', and installed conda, conda-env, html5lib. I'm unsure about higher-priority channel part.
But this answered my problem!!
Problem appears after installing tensorflow 1.3.0.
Reinstall html5lib.
conda uninstall html5lib --force
conda install html5lib
Solves the problem temporarily until next pip install --upgrade tensorflow.
Had the same problem with pip install --upgrade tensorflow-gpu as well.
I try to make an easy Python gui, therefore I need to import tkinter. This package is available in Python 3, so I need that interpreter, but I can't get it started in Pycharm. It always asks to install packaging tools and then I get the same error everytime and I can't seem to fix it. I get the following:

I already searched some fixes but none actually worked.
Python PIP might not be installed. In Debian based distribution:
sudo apt-get install python3-pip
should solve if you use Python 3.
For Python 2.7x
sudo apt-get install python-pip
Close PyCharm and re-open it.
In this case, it may be possible that python pip (package installer) is not installed. So try installing that first.:
sudo apt-get install python3-pip

Have you tried installing it with sudo ? You usually need to use sudo to install some dependencies

I was wondering if anybody had some insight as to fixing this? I read that there may be reference in usr/bin to older versions of software, this is possible, but this computer is on the newer side. Is the best bet to go in and clear all references to 'virtualenv' (all that I can find that is
)?
Thank you!
The problem is that you're trying to install a package to a location that typically requires root privileges. You can do as #Vince West suggested and run sudo pip install virtualenv, or you can do pip install --user virtualenv, which will install packages to ~/.local/lib/python<version>/site-packages. If you go that route, you'll likely want to make sure $HOME/.local/bin is included in your $PATH.
