label-studio: AttributeError when trying to run label-studio after installing it via pip

Describe the bug Installed Label Studio via pip, as described on main page. However, when I try to run it a Python exception is being thrown:

AttributeError: module 'rest_framework.serializers' has no attribute 'NullBooleanField'. Did you mean: 'BooleanField'?

Tried installing in two separate environments, using python’s default venv and using conda, both times same error occured.

To Reproduce:

run pip install label-studio
run label-studio

Environment (please complete the following information):

OS: Microsoft Windows 10
Label Studio Version: latest version from PyPi

I had the same problem with djangorestframework v. 3.14.0

pip install djangorestframework=3.13.1 made the problem go away; label-studio seems to work as intended.

It seems that drf_yasg package caused the error (reported here).

To temporarily fix the issue, …

Go to your ‘drf_yasg’ package in your environment. In your case based on the error message, C:\Users\some.user\Miniconda3\envs\label-studio\lib\site-packages\drf_yasg.
Open .\inspectors\field.py file and replace all ‘NullBooleanField’ to ‘BooleanField’.
Restart label-studio by running the command label-studio.

This is only the workaround if you have urgent work to do. Use with care.

The problem is here:

Current platform is win32, apply sqlite fix Can’t load sqlite3.dll from current directory

You can download sqlite manually and place it in the directory where you run LS. Or you can use Anaconda Python, it has the correct SQLite lib inside.

x32 - https://www.sqlite.org/2022/sqlite-dll-win32-x86-3400000.zip x64 - https://www.sqlite.org/2022/sqlite-dll-win64-x64-3400000.zip

please do we need to install SQLite database before installing label studio ?

khadijakhaldi on Jul 20, 2023

@vvaradarajan Could you try this:

pip install -U drf_yasg
pip install -U djangorestframework

Will it help?

makseq on Jan 30, 2023

HI guys pip install -U label-studio does not improve anything. As a good practice, to mark the problem as solved, it is not enough to fix the problem in the source code, You have to release the version with fixes.
