Error "The ordinal 242 could not be located in the dynamic link library C:\Users\XXXX\AppData\Local\Continuum\anaconda3\Library\bin\mkl_intel_thread.dll." when trying to use pyinstaller to get my exe file.

Hi, I get the error "The ordinal 242 could not be located in the dynamic link library C:\Users\XXXX\AppData\Local\Continuum\anaconda3\Library\bin\mkl_intel_thread.dll." when trying to use pyinstaller to get my exe file. 

Pyinstaller works just fine if my python script is just print("hello world"). But I keep getting the above error if my script involves tkinter and threading. Anybody can help me out? Really appreciated. Got no idea how to fix this after googling around.
