I am trying to use virtualenv to install some python modules for deep learning. I'm on Ubuntu 18.04 where there was python2.7 intalled. Somehow I installed python 3 and made a virtualenv called dl4cv where I can work on deep learning projects. Now that I'm trying to make a new virtualenv mkvirtualenv temp after installing virtualenvwrapper, I got an error as shown below :
hdafa#hdafa-HP-ProBook-450-G5:~$ mkvirtualenv temp
Running virtualenv with interpreter /usr/bin/python2
Traceback (most recent call last):

OSError: [Errno 13] Permission denied: '/home/hdafa/.virtualenvs/temp'
any idea of how I can fix it?
You've been using sudo too much. Please stop.
First, fix permissions of your home:
sudo chown -R hdafa /home/hdafa
From now on please use only virtual environments and avoid sudo except for system administration tasks.
It looks like your OS is denying permission to make a directory. Try running the command with root permissions: sudo mkvirtualenv temp. The keyword sudo uses root permissions, and so it should be able to create the directory that it needs to.

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.

I think the problem is with permissions in file system. The error says "read-only file system"
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 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

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
When I run the command python -m virtualenv venv
I get the following output:

When I navigate to the 'venv' folder the file structure is completely unpopulated with only C:\Python\sites\venv\Lib\site-packages (which is completely empty)
I have tried re-installing virtualenv and googling the issue with no avail. Please advise
Have you correctly installed the python on your machine? I also run into a similar issue earlier. It was caused by my python installation.
You see if you check your python path and go to the Lib folder, I assume there was no site.py. You can:
reinstalled your python, make sure it has correctly installed (check the Lib and Script folder)
correct your python path to your user/system environment: I assume you are using Window OSX, e.g: setx PYTHONHOME "C:\<your_python_path>"; add that to your path: setx PATH "%PATH%;%PYTHONHOME%"
Don't forget to add the Script path as well, if you want to access pip without python -m
Cheers!!
I receive a funny error when trying to install virtualenv:

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.
I am following these steps to setup a virtual environment in Ubuntu 13.10 64-bit.

After setting up the various things in bashrc and then on executing source .bashrc. I get the following traceback.

virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenv has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.
It seems that it is unable to find the installation of python. I too am puzzled bacause on executing "which python", I get /usr/bin/python but when I got /usr/bin, I am unable to find the python directory .Please help...
Thanks.
Permission denied seems like u need to be root to do that. Maybe you should use "sudo" before using the command which gives you the error
Did you install virtualenvwrapper? If yes, then sudo like mentioned by user2270433. If no, then install that and proceed with the instructions. I haven't used virtualenvwrapper, but the standard steps for virtualenv in my bootstraps are like this...
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
sudo -n python ez_setup.py && sudo python get-pip.py
sudo -n pip install virtualenv
