There are many different variations of bar charts. Bar charts is one of the type of charts it can be plot. Matplotlib is a Python module that lets you plot all kinds of charts. You can create all kinds of variations that change in color, position, orientation and much more. You would create a new virtualenv with access to all the packages already installed in your old virtualenv, but with access to the system site packages as well.Bar charts can be made with matplotlib. This can be used when you already have a virtualenv that was created without the -system-site-packages flag but that has all your required packages (which took a long time to build in the Nano). Realpath ref/lib/python3.6/site-packages > myapp/lib/python3.6/site-packages/base_venv.pth -system-site-packages In other words, create a virtualenv myapp using the -system-site-packages flag from an already created virtualenv ref, as follows: virtualenv -p ref/bin/python myapp The second method, which came in very handy in the Nano, was to use virtualenv inheritance. For example: virtualenv -p ref/bin/python myapp -system-site-packages The first one is to use the -system-site-packages flag when creating the virtualenv, so that packages installed system wide are accessible from the virtualenv. I found two methods to get access (not installing) to matplotlib inside a virtualenv.

You can change the version of the repo cloned by changing the version number, corresponding to tags on the matplotlib repo. This will add the matplotlib repository into the default path that pip packages are installed for the Jetson Nano, edit the sources.list file, and restore the sources.list file.

Sudo mv /etc/apt/sources.list~ /etc/apt/sources.list Sudo sed -Ei ‘s/^# deb-src /deb-src /’ /etc/apt/sources.listĬd ~/.local/lib/python3.6/site-packages/matplotlib Sudo cp /etc/apt/sources.list /etc/apt/sources.list~ Here’s a complete script which you can use that installs dependencies properly with no errors for me on a Jetson Nano. Which is solved by editing /etc/apt/sources.list. This command may cause the following error:Įrror :: You must put some ‘source’ URIs in your sources.list Sudo apt-get build-dep python3-matplotlib -y Just installing from source or by pip by itself leads to some missing C header errors, which is solved by: For everyone trying to install a more recent version of matplotlib than provided by the Debian package, try installing from source.
