This error message generally indicates that there is a problem with the thread synchronization in a Python program. More specifically, it suggests that a function that requires the Global Interpreter Lock (GIL) to be held has been called while the GIL is not held. This can cause a number of issues such as race conditions or data corruption, which can ultimately lead to the program crashing. To address this error, the programmer will need to review the code and ensure that all threads are properly synchronized and that the GIL is held when necessary.
