Pyinstaller noconsole option makes exe fatal error [Solved]

hi I am very new to programming. I made sciprt with Anaconda virtual environment and

python 3.5.6, pyinstaller 3.5, selenium 3.141, pyqt5 5.13.2, pymysql 0.9.3

it works fine in atom. and also works fine when I do 

pyinstaller --onefile myapp.py

but when I do 

pyinstaller --noconsole --onefile myapp.py

in command prompt it says completed successfully. but when I click myapp.exe, fatal error massage box show up. like below

fatal error detected

failed to execute script MyScript

I searched alot, but couldn't find why.

I did some work as https://stackoverflow.com/a/47229908/12471379 still don't know how to fix.

01.07.20

now I got nothing, not even devTool thing from cmd when I run myapp.exe

which made by pyinstaller --onefile myapp.py

still don't work with --noconsole

01.08.20

I just make new venv, did

pyinstaller --noconsole --onefile --noupx myapp.py

only warning I got is 

23142 INFO: Loading module hook "hook-PyQt5.py"...
23352 WARNING: Hidden import "sip" not found!

but since it's only warning. I ignore this. and don't work getting crazy....

01.09.20 problem solved.

I was so stupid.... I believe this happen because I am very new to programming I will leave this so no beginner would make same mistake as me.

if you are not native English speaker. you might have some unicode changing in your script. like this 

import sys
import io
sys.stdout = io.TextIOWrapper(sys.stdout.detach(), encoding = 'utf-8')
sys.stderr = io.TextIOWrapper(sys.stderr.detach(), encoding = 'utf-8')

I just copy and paste this from my lecture video. so didn't know nothing about this. and still don't know. I think this translate error to my language.

problem was this part.

import io
sys.stdout = io.TextIOWrapper(sys.stdout.detach(), encoding = 'utf-8')
sys.stderr = io.TextIOWrapper(sys.stderr.detach(), encoding = 'utf-8')

don't know exactly why. I just erase it. and change servier.py as https://stackoverflow.com/a/51118530/12471379

than do pyinstaller --clean --noconsole --onefile --noupx myapp.py

works!!!

I know this is so basic mistake. but I hope this might help some beginner.

It seems that your issue was related to the reconfiguration of the encoding of the system standard output and standard error sys.stdout and sys.stderr.

If you still want to change the encoding of stdout and stderr, the following code should works (without stopping you to use pyinstaller with the --noconsole option):

import codecs
if sys.stdout.encoding != 'UTF-8':
    sys.stdout = codecs.getwriter('utf-8')(sys.stdout.buffer, 'strict')
if sys.stderr.encoding != 'UTF-8':
    sys.stderr = codecs.getwriter('utf-8')(sys.stderr.buffer, 'strict')
