“Homebrew + Python On Mac Os X 10.8: Fatal Python Error: Pythreadstate_get: No Current Thread Importing Mapnik” ~ bbaz
Python is used extensively in creating maps and geospatial applications, and the Mapnik library is a powerful tool that allows developers to create beautiful and informative maps. However, sometimes when trying to import Mapnik, Mac OS X 10.8 users may encounter a Fatal Python Error message, which can be frustrating and time-consuming to troubleshoot. In this blog, we’ll explore some common causes of this error and provide tips for resolving it.
Mapnik is a free, open-source mapping toolkit that runs on multiple platforms, including Mac OS X 10.8. It provides a range of features for creating custom maps, such as rendering tiles, styling data, and creating labels. Python is the primary language for using Mapnik, and the Mapnik Python bindings allow developers to easily use Mapnik from within Python code.
What is the Fatal Python Error?
The Fatal Python Error is an error that occurs when the Python interpreter encounters an internal error. This can happen for a variety of reasons, and in the case of importing Mapnik, it often indicates a problem with the Python environment or installation. When attempting to import Mapnik, the user may see an error message such as:
Fatal Python error: PyThreadState_Get: no current thread
Causes of the Error
There are several known causes of the Fatal Python Error when importing Mapnik on Mac OS X 10.8:
|Conflicting Python installations
|If there are multiple versions of Python installed on the system, this can cause conflicts with Mapnik.
|Missing or outdated dependencies
|If Mapnik’s dependencies are not installed or are outdated, this can cause issues when importing.
|Incompatible Mapnik and Python versions
|If the version of Mapnik being used is not compatible with the installed version of Python, this can result in errors.
|Incorrect installation path
|If Mapnik is not installed in the correct location, this can cause issues with importing.
Check for Conflicting Python Installations
The first step in troubleshooting the Fatal Python Error when importing Mapnik is to check for conflicting Python installations. To do this:
- Open a terminal window.
- Enter the command
which pythonto see which version of Python is being used by default.
- If there are other versions of Python installed, you can locate them using the command
find / -name python* -print.
- If you find other installations, you may need to remove them or adjust your PATH environment variable.
Check for Missing Dependencies and Update Them
The next step is to ensure that all of Mapnik’s dependencies are installed and up-to-date. You can do this using the following commands:
$ sudo apt-get update$ sudo apt-get upgrade$ sudo apt-get install libboost-all-dev libxml2-dev libbz2-dev libjpeg-dev libpng-dev libtiff-dev libicu-dev python-dev
Check Mapnik and Python Versions
It’s important to ensure that the version of Mapnik being used is compatible with the installed version of Python. You can check this by entering the following command in a terminal window:
$ mapnik-config --version
You can compare the output of this command to the version of Python you are using by entering
Check Installation Path
If all of the above steps fail, it’s possible that Mapnik is not installed in the correct location. By default, Mapnik installs to
/usr/local, but this can vary depending on how it was installed. You can check the installation path by entering:
$ python -c import mapnik; print(mapnik._mapnik.library_path)
If this command returns an error or a path that is inconsistent with your installation, you may need to adjust your installation or PATH environment variable.
The Fatal Python Error when importing Mapnik on Mac OS X 10.8 can be a frustrating problem, but there are several steps you can take to troubleshoot and resolve it. By checking for conflicting Python installations, ensuring that all dependencies are up-to-date, verifying compatibility between Mapnik and Python versions, and checking the installation path, you can get back to creating beautiful maps with ease.

When encountering a fatal Python error while importing Mapnik on Mac OS X 10.8, users may have some questions and concerns. Here are some commonly asked questions and their corresponding answers:
What causes the fatal Python error when importing Mapnik?
The fatal Python error is caused by a compatibility issue between Mapnik and the Python version installed on your Mac OS X 10.8 system. Specifically, Mapnik requires Python 2.7 or later, but older versions of Mac OS X come with Python 2.6 installed by default. Upgrading to a newer version of Python should resolve the issue.
How do I upgrade Python on my Mac OS X 10.8 system?
There are several ways to upgrade Python on a Mac OS X 10.8 system, but one common method is to use a package manager such as Homebrew or MacPorts. Both of these package managers allow you to easily install and manage different software packages, including Python. To install Python using Homebrew, for example, you can run the following command in your terminal:
brew install python
After the installation is complete, you should be able to import Mapnik without encountering the fatal Python error.
Are there any other potential solutions to the fatal Python error?
In addition to upgrading Python, there are a few other potential solutions to the fatal Python error when importing Mapnik on Mac OS X 10.8. One possible solution is to manually install a compatible version of Mapnik that works with Python 2.6. Another option is to use a virtual environment such as Anaconda or Virtualenv to manage different Python versions and dependencies. However, upgrading to a newer version of Python is generally the most straightforward and recommended solution.
