I’ve got a weird problem with one of my Python scripts. It creates a chart with animation, and this animation works fine on Windows and Linux, but on Mac OS it just doesn’t show up. Here’s a video demonstration:

Matplotlib: Installation/Set-up This is a short tutorial on how to install Matplotlib in macOS (10.4/Mojave). We will use the pip package installer for Python. Matplotlib was not supported on Mac before. But now we can install it on Mac! First, search Xcode (a developer tool) in App Store. It will be the first one in the search results. Next, open a terminal, and type the commands shown in the following. $ pip3 install numpy $ pip3 install matplotlib.
To run the script I installed only matplotlib and numpy packages, so the environment on all 3 systems (Windows, Linux, Mac OS) should be the same. Just in case, here they are:
How To Install Matplotlib
Mac doesn’t have a preinstalled package manager, but there are a couple of popular package managers you can install. For Python 3.5 with Macports, execute this command in a terminal: sudo port install py35 - numpy py35 - scipy py35 - matplotlib py35 - ipython + notebook py35 - pandas py35 - sympy py35 - nose. Matplotlib has not been officially released for Python 3.7 yet. As of this writing, a 3.7 version for Mac and Linux has been uploaded to PyPI earlier today, which means the Windows versions are probably coming very soon. Pip will probably work after that. Similarly, no 3.7 compatible versions have been put onto conda-forge or integrated into the main conda repo yet. Download matplotlib for Mac 2.1.0 for Mac. Fast downloads of the latest free software!
Ichat app for mac. I’ve tried other simple plot animation samples (for instance, the ones from matplotlib documentation), and all of them work fine on Mac OS, so there has to be something wrong with my particular script. However, the fact that this very same script works on Windows and Linux confused me a lot. As a side note, you might have noticed that animation speed is different between Windows and Linux (the latter is faster), and I’ve no idea what could be the reason of that either, though it’s not so important here. Macos google hangouts app.
I’ve also tested my script on 3 other Macs with different Mac OS and Python versions installed, just to make sure that it’s not my environment who messes things up, but it was the same on all of them - no animation showing up.
After submitting a question at Stack Overflow and also at matplotlib forum, I thought about reading the documentation (classic).
The right backend
There I soon enough discovered the backends section. That helped me to google some more ideas, for instance this answer shown what’s needed to make animation from my script work in Jupyter notebook - just a single line in the very beginning of the script:
And then animation started to work. Okay, so what backend does Jupyter uses in this case then:
Matplotlib Mac Os
It returned
TkAgg
- so that’s what can show animations in my script! Now I only need to set the same backend in my standalone script.https://clevermex859.weebly.com/blog/kik-messenger-for-mac-free-download. By the way, if you are curious, without
%matplotlib Tk
Jupyter reports module://ipykernel.pylab.backend_inline
value for backend.With pyplot.rcParams
Using the same print statement, I’ve discovered what backend is used by default when running my script in terminal:
MacOSX
. Right then, so this backend is incapable to run my animation for some reason. But since I now know the backend that is capable, I’ve set it like this:But even though it reported a new backend in the output, the animation still wasn’t showing up:
Mifare cracking. So setting the backend via
plt.rcParams['backend']
isn’t supported? https://nvever612.weebly.com/running-mac-classic-apps-on-os-x.html. That’s a bit unexpected, as according to the documentation, it should be.With matplotlib.use
Anyway, after some more googling I’ve found this answer, and that was what finally worked:
Now my script runs and shows the animation. It also prints the following warning to the output:
…which is due to the fact that default Tcl/Tk on Mac OS is outdated (
8.5
at the moment), and if you (like me) are getting Python from Homebrew, then it won’t be trivial to link it with the latest version of Tcl/Tk. But for now it works as it is, so it’s all good for the time being.[17.09.2020] Update: Fixed script
As it was pointed out in the bugreport, the
line
is added anew to the plot each time inside animate()
function, instead of modifying existing line, and that’s what was causing the chart to go all rainbowy.After fixing the script like this:
I now get the following result even with default
MacOSX
backend:If video doesn’t play in your browser, you can download it here
Almost good, except for this horizontal line (by the way, it’s not present with
TkAgg
backend). Setting blit=False
gets rid of this line, and also causes the animation to play considerably slower (but that’s not really a problem).Watch dogs 2 free download mac. This webpage provides instructions to install Matplotlib in Windows and Mac.

For Windows
You can download Matplotlib for Windows at http://matplotlib.org/downloads.html.
he the downloaded library version should match the Python version we are using in the lab. For instance, when you open the URL to download Matplotlib, you will see different versions:
You should download matplotlib-1.4.3.win-amd64-py3.4.exe if the computer is 64-bit Windows platform. “matplotlib-1.4.3” denotes the version of Matplotlib; “win‑amd64‑py3.4” means this library works on 64 bits Windows platform, with Python v3.4. Similarly, if your computer is 32 bits Windows platform, you should download matplotlib-1.4.3.win32-py3.4.exe instead.
If during installation you get an error saying that Python 3.4 is not found, but you are sure that you have Python 3.4 installed in your computer, try the following:Open IDLE and check the version of your python 3.4 (32-bit or 64-bit). Download and install the 64-bit matplotlib if your python is 64-bit; otherwise download the 32-bit one.

For Mac
Matplotlib was not supported on Mac before. But now we can install it on Mac!
First, search Xcode (a developer tool) in App Store. It will be the first one in the search results. Install Xcode!

After the installations are finished, check if numpy and matplotlib are installed successfully. In the terminal, type:
You will enter python 3.4 if you have it installed in your computer. Then type:
If an error ImportError: No module named 'numpy' is raised, then numpy is not installed successfully.
