Feedback for “Windows 1click Installer” RuntimeError: Form data requires "python-multipart" despite installation (Paid User)

[shonsubong]

Hello, I am a paid user of IOPaint, and I’m experiencing an issue during setup that I haven’t been able to resolve. The following error repeatedly appears, despite having installed all dependencies as directed:

Error:

RuntimeError: Form data requires "python-multipart" to be installed.
You can install "python-multipart" with:
pip install python-multipart

I've confirmed that python-multipart is installed and have even reinstalled it with --force-reinstall, yet the issue persists. Here is my setup:

• Platform: Windows 10 (Version 10.0.19045)
• Python Version: 3.10.6
• torch: 2.1.2+cu118
• IOPaint Version: 1.4.4
• Additional Dependencies: All other required packages are installed as specified in the documentation.

The error specifically occurs when running win_config.bat, and it seems related to FastAPI and Gradio integration. I have tried activating the environment explicitly and restarting my terminal, but to no avail.

Steps Taken:

1. Verified installation of python-multipart in the virtual environment.
2. Reinstalled python-multipart with --force-reinstall.
3. Restarted terminal and reactivated the environment.

If there are any additional steps or specific configurations I should try, please let me know.
Thank you for your assistance!

I have all the required environments and dependencies in the installer folder. Why should I need to reinstall them?
The win_setup.bat file executed successfully in the cmd window.
Should the IOPaint-v1.1.zip file be extracted to a specific folder?

I found a similar issue fastapi/fastapi#5144 (comment), it's because the API of python-multipart changed in version 0.0.14. Can you try installing version python-multipart==0.0.12?

update:

The issue has been fixed in python-multipart==0.0.16, so upgrading to 0.0.16 should also work. Kludex/python-multipart#176
