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 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

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 want to convert Python code into standalone executable , the code uses numpy, scipy, and Pymc3 modules. I am using Python 3.6.4. I have created the project using Virtual Environment in Pycharm IDE. The command that I used to run pyinstaller is as follows:
venv/Scripts/pyinstaller --onefile src/POD.py
venv being the folder where virtual environment is stored and src being the folder where my Python source code ie. POD.py is saved. Pyinstaller runs just fine generates some warning message, but when I try to run the executable generated by pyinstaller it thrown as error
Traceback (most recent call last):

[4756] Failed to execute script POD
Seems like it is trying to find the file dimshuffle.c outside of the virtual environment. In-fact the I can see that there is folder inside virtual environment which has the dim_shuffle.c code. I can find it inside virtual environment in following folder.
venv/Lib/site-packages/theano/tensor/c_code/dimshuffle,c
My question is how do I instruct pyinstaller to look for dimshuffle inside virtual environment folder?
You can,
extend the sys.path by editing the spec file.
pyi-makespec --paths=/path/to/thisdir \
--paths=/path/to/otherdir myscript.py
List the hidden imports using the spec file.

I'm attempting to follow this tutorial to install the natural language processing package spaCy into a python 3 anaconda environment, windows 8
I opened console, cd-ed to my site-packages folder, activated environment, pip-ed for install, everything seemed fine except I couldn't run the second command here
$ pip install spacy
$ python -m spacy.en.download
Now I can successfully load the package but when I run the second line below, I get the following error
>>> from spacy.en import English #this works
>>> nlp = English() #this doesn't
Traceback (most recent call last):

I think that it is due to the fact that I couldn't run python -m spacy.en.download
Can anyone give me an idea of what python -m spacy.en.download is supposed to be doing?
Can anyone provide a walkthrough for how to get spaCy installed in an anaconda environment?

appreciate any help or advice you can provide
You have hit this bug which should be already fixed in the last version. Apparently spacy can't download the data because the destination already exists (may be from a previous interrupted download). A workaround would be to delete the /temp/data folder and retry the download.

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
