Issue

**After creating virtual environment and installing requirements.txt, carried out following steps to convert .py file into .exe ** using pyinstaller library

step 1 : pip install pyinstaller
step 2 : pyinstaller --name GrammarCorrector --onefile --windowed new_gram1_Tkinter.py --hidden-import cymem.cymem

Then i got this AttributeError:

AttributeError: 'NoneType' object has no attribute 'flush'

I raised issue in pyinstaller repository, and i got answer as followed below from @bwoodsend who is a maintainer

You should be able to get the same error without PyInstaller if you run your source code using pythonw instead of just python. Raise a bug to transformers if they have their own windowed-mode-naive logger. https://github.com/orgs/pyinstaller/discussions/7689#discussion-5270292

Who can help?

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction

I want my .py file in .exe file and when i am doing that using pyinstaller it is giving Attribute error when i asked pyinstaller developers on repository they suggested me to raise bug report on transformers saying that if they have their own windowed-mode-naive logger.

Expected behavior

i want .exe file from .py

Hello, I have encountered the same problem as you, did you solve it?

Hi! I also encountered this error. I'm building a package with pyinstaller which works on MacOS with M2 amd64. Running inside of a Windows VM running Windows 11, this fails with the same error.

你好！我也遇到了这个错误。我正在构建一个在 MacOS 上使用 M2 amd64 的软件包。在运行 Windows 11 的 Windows VM 中运行，此操作失败并出现相同的错误。pyinstaller

You can add this code before your transformers import
if sys.stdout is None:
sys.stdout = open(os.devnull, "w")
if sys.stderr is None:
sys.stderr = open(os.devnull, "w")

if by chance you have this error and you have a Virtualenv, remember to generate the pyinstaller exe from inside the virtual environment, I solved it like this
