What is the meaning of the Pyinstaller error message "Failed to determine version"?

edit

The error message "Failed to determine version" in Pyinstaller means that the tool was unable to determine the version of the Python module or package being used. This could be due to missing or incorrect information in the module or package, or there may be an issue with Pyinstaller itself. The error typically occurs during the creation of a standalone executable file from a Python script.
