Fatal Python error: pythreadstate_get: no current thread

This error can have several causes, but the most common is that your Python code is trying to use a thread that doesn’t exist.

To fix this, you need to find the code that’s trying to use the thread and either get rid of it or make sure that the thread exists before the code is run.

If you’re not sure how to do this, please post a question on Stack Overflow (include your code!) and we’ll be happy to help.

What is a fatal Python error?

Fatal Python error: PyThreadState_Get: no current thread

This error can be caused by a number of things, but the most common is either a corrupt or missing Python interpreter, or a corrupt or missing Python threading library.

How to fix a fatal Python error

If you’re seeing a “fatal Python error pythreadstate_get no current thread” error, it means that your Python interpreter has crashed. This is usually caused by an issue with your code, but it can also be caused by a corrupt Python installation or a problem with your computer’s hardware.

There are a few things you can do to try to fix this error:

• Reinstall Python. This will overwrite any corrupt files and might fix the problem.
• Try running your code in a different Python interpreter. If you’re using Anaconda, you can try switched to the built-in Python interpreter by running “conda deactivate” in your terminal.
• If you’re on Windows, try reinstalling the Microsoft Visual C++ Redistributable for Visual Studio 2015 (x86). This is a common cause of crashes on Windows.
• If you’re using a virtual environment, try recreating the environment from scratch. Sometimes, corrupt files can cause problems with virtual environments.
• Try running your code on a different computer. If the problem only happens on one computer, it could be an issue with that computer’s hardware.
  Conclusion
  The error message indicates that the Python interpreter can’t find the corresponding thread state for the current thread. This can happen if the thread state is not properly initialized, or if Python’s implementation of threads has changed in such a way that the interpreter can no longer find the thread state for the current thread. If you are using a third-party module that uses threads, you may need to update it to use the new Threading API.
