I have been trying to run RStudio Quarto script in a fresh Ubuntu 20.04 installation but got into some trouble. Some Python packages that are required to run the simple hello.qmd were not there. I was getting these errors:
MoudleNotFoundError: No module named 'nbclient'
and a second error:
ModuleNotFoundError: No module named 'matplotlib_inline'
The first error was due to I had install the nbclient package. My default Python installation is python2.7. Quarto will not run well with Python 2.7; we should try with 3.7+. If your Linux doesn't come with it by default, this can easily be addressed by installing another Python version and configuring multiple Python versions with the help of the command:
sudo update-alternatives --config python
If no Python version shows up, then it means you have first to configure all your installed Python versions. This is very well explained at https://www.rosehosting.com/blog/how-to-install-and-switch-python-versions-on-ubuntu-20-04/
Once you have configured all your Python versions, every time that you run
sudo update-alternatives --config python, you will be prompted to enter the Python version you want as default. If you have a fresh Ubuntu 20.04, most likely that you have two: Python 2.7 and Python 3.8. Select 3.8 and you will fine. Quarto won't work with Python 2.7.
After you have python3 running and switched into, install nbclient with:
pip install nbclient.
The first error will now pass, but most likely you will get now
ModuleNotFoundError: No module named 'matplotlib_inline'. This is because you also need to install the package matplotlib-inline. This is not documented in the installation instructions of Quarto. But easy to fix. Run:
pip install matplotlib-inline
Now, go back to your VS Code, open the command palette and run Quarto: Render, or just type from the terminal:
quarto preview hello.qmd --no-browser --no-watch-inputs
You are done!

I'm trying to build an HTML-page of my Jupyter notebook. I tried to run jupyter-book build mybookname but the command can't be found.
I tried to also install jupyter-book using the command pip install jupyter-book and added jupyter-book file path to environment variables, but I still can't build my book.
What should I do?
MY jupyter notebook didn't work after installing and calling in CMD.
then i only use "pip install simplejson" in command prompt (cmd) . Then i write "jupyter notebook" and it work!
someone uses "pip uninstall simplejson" before "pip install simplejson".
Maybe python needs to reinstall something (pip install/unistall).
I have successfully installed the Caffe on Ubuntu 18.* using
`sudo apt-get install caffe-cpu`
The which caffe returns /usr/bin/caffe
I am successfully able to run caffe command on terminal, but problem is running the test files, as they are link to build directories of caffe and the problem is if I manually get the github repository of caffe and make build, it keeps failing and some of the dependencies candidates dont't have an installation candidate on Ubuntu 18.
Also all the examples on net available are for the previous type of manually built caffe
Normally, it will use with the default python in /usr/bin/python3. You can check
/usr/bin/python3
>>> import caffe
With the python in /usr/bin/python3, it does not require to add any addtional PYTHONPATH
After many different ways of trying to install jupyter, it does not seem to install correctly.
May be MacOS related based on how many MacOS system python issues I've been having recently
pip install jupyter --user
Seems to install correctly
But then jupyter is not found
where jupyter
jupyter not found
Not found
Trying another install method found on SO
pip install --upgrade notebook
Seems to install correctly
jupyter is still not found
where pip /usr/local/bin/pip
What can I do to get the command line jupyter notebook command working as in the first step here: https://jupyter.readthedocs.io/en/latest/running.html#running
Short answer: Use python -m notebook
After updating to OS Catalina, I installed a brewed python: brew install python.
It symlinks the Python3, but not the python command, so I added to my $PATH variable the following:
/usr/local/opt/python/libexec/bin
to make the brew python the default python command (don't use system python, and now python2.7 is deprecated). python -m pip install jupyter works, and I can find the jupyter files in ~/Library/Python/3.7/bin/, but the tutorial command of jupyter notebook doesn't work. Instead I just run python -m notebook.
My MacOS has python 2.7, I installed python3 with brew, then the following commands work for me
brew install python3
brew link --overwrite python
pip3 install ipython
python3 -m pip install jupyter
You need to add the local python install directory to your path. Apparently this is not done by default on MacOS.
Try:
export PATH="$HOME/Library/Python/<version number>/bin:$PATH"
and/or add it to your ~/.bashrc.
Try solving this with Conda or Poetry.
Poetry makes it a lot easier to manage Python dependencies (including Jupyter) and build a virtual environment.
Here are the steps to adding Jupyter to a project:
Run poetry add pandas jupyter ipykernel to add the dependency
Run poetry shell to create a shell within the virtual environment
Run jupyter notebook to to fire up a notebook with access to all the virtual environment dependencies
The other suggested solutions are just band-aids. Conda / Poetry can give you a sustainable solution that's easy to maintain and will shield you from constant Python dependency hell.
I installed wordcloud via conda in Windows 64
conda install -c conda-forge word cloud
but that is python 3.4.
I want to install word cloud in python 3.6
but i did search the google.
but it is not effect. so please teach me....
Anaconda Python 3.6 version
For Windows
==== Installation of wordcloud package ====
download wordcloud‑1.3.2‑cp36‑cp36m‑win_amd64.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#wordcloud
Copy the file to your current working directory
Open command prompt from Tools
python -m pip install wordcloud-1.3.2-cp36-cp36m-win_amd64.whl
It should work now
For MAC
pip install wordcloud
There is a solution, you can download a third party package for Python 3. Following the below steps helped me solve the problem.
Wordcloud_successful_install
Download wordcloud‑1.3.2‑cp36‑cp36m‑win_amd64.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#wordcloud
Copy the file to your current working directory
Open command prompt from Tools
Python -m pip install wordcloud-1.3.2-cp36-cp36m-win_amd64.whl
This will work:
1. create virEnv: conda create -n yourenvname python=3.5 anaconda
2. source activate yourenvname
3. conda install -c conda-forge wordcloud
Install wordcloud from the following page:
https://pypi.org/project/wordcloud/
Note: command: pip install wordcloud
Note: run the above command in Anaconda cmd prompt
Pre-requisities for instaling wordcloud is to install Visual C++(I got this error to install. So, you may give a try).This requires almost 4GB space. Once installed, restart your machine and then try the 1st step. It should be successful this time.
Ok. I solved my issue using wheels. Here are the steps:
Download the .whl file compatible with your Python version and your windows distribution (32bit or 64bit) from here https://www.lfd.uci.edu/~gohlke/pythonlibs/#wordcloud
cd to the file path
Run this command python -m pip install
If I install the latest stable 1.2.7 django-haystack with sudo pip install django-haystack, it works fine. But after uninstalling it and installing the very latest dev version 2.0.0 BETA instead as suggested on the main page:
pip install -e git+https://github.com/toastdriven/django-haystack.git#master#egg=django-haystack
Despite the success messages below, it seems like it is not properly installed:

Cleaning up...
because when I go into the django shell environment and do a
>>> from haystack import indexes
Traceback (most recent call last):
File "<console>", line 1, in <module>
ImportError: No module named haystack
I have followed the instructions and have
INSTALLED_APPS = (... 'haystack',) in there
I had this problem before, but could never solve it. sudo pip install default works fine, but as long as I get the latest Git version, my django doesn't seem to see it.
What could I be missing?
Many Thanks for your advice,
UPDATE
Apologies, but it seems the error is happening only within Aptana Studio 3.0. In Django Shell I can do the import after all. I am still dazzled, as this should be the same. Why can Aptana see the libraries when installing with sudo pip install django-haystack but not if using latest Git version? What could go wrong there please?
UPDATE 2
full sys.path
['/home/kaveh/projects/cb', '/usr/local/lib/python2.7/dist-packages/requests-0.13.9-py2.7.egg', '/home/kaveh/projects/cb/src/django-haystack', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']
I finally got it working.
As I said the problem is pip install -e git+https://github.com/toastdriven/django-haystack.git#master#egg=django-haystack is apparently not working.
I simply uninstalled it and made sure its deleted.
Then I simply downloaded the source as zip file, extracted it and
python setup.py build
sudo python setup.py install
This way it will guaranteed be working. Hope this helps someone.
