Pyinstaller Matplotlib [Errno 2] No such file or directory: 'C:\Users\User\AppData\Local\Temp\_MEI142562\matplotlib\mpl-data\matplotlibrc'

I want to make a standalone exe with pyinstaller.

If I execute the .exe file I get the following Error:

C:UsersUserDesktopinvpepeshort>.invpepe.exe
Traceback (most recent call last):
  File "invpepe.py", line 14, in <module>

FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\User\AppData\Local\Temp\_MEI142562\matplotlib\mpl-data\matplotlibrc'

I hope someone can suggest a fix.
