IMPORTANT NOTICE - Upcoming removal of Python 2.7 and 3.7 interpreter in ShotGrid Desktop

Hi everyone,

Wanted to share an update for our plans regarding Python 3.9 support in ShotGrid Desktop. By Nov. 1, 2022, ShotGrid Desktop will ONLY support Python 3.9 , and stop shipping a working copy of the Python 2.7 and Python 3.7 interpreter.

Why is this being done?

We are removing Python 2 for security purposes, to ensure that ShotGrid Desktop is always running on the most secure version of Python recommended by the VFX Reference Platform.

What if I want to keep using an older copy of ShotGrid Desktop?

No worries! We will keep supporting Python 2.7 and 3.7 for the foreseeable future for our ShotGrid Integrations. We know a lot of you are still using DCCs that only support Python 2.7 and 3.7, or don’t want to redeploy a new version of ShotGrid Desktop. The automatic updates we provide for Desktop and the ShotGrid Integrations will still support Python 2.7 and 3.7. The only difference is Python 3.9 will be the only Python that ships with newer installers of ShotGrid Desktop .

If you want to download older versions of ShotGrid Desktop that still support Python 2.7 and 3.7, you can grab versions 1.6.1 to 1.7.x here.

I’m ready to leave Python 2 behind, how do I do it?

If you’re using the basic integration, you’re good to go. All our tools are Python 2/3 compliant, so installing a new ShotGrid Desktop that only bundles Python 3 will not be an issue. Note that this change only impacts the ShotGrid Desktop experience. All your DCCs that do not ship with a Python 3.9 interpreter can still be launched from ShotGrid Desktop.

If you’ve customized your ShotGrid projects integrations i.e. using an advanced integration and you are relying on Desktop’s built-in Python interpreter; you may have to make changes before you install the new version. You’ll need to make sure that any application that runs in the tk-desktop engine, either at the project or site level, is compatible with Python 3.9.

Don’t hesitate to reach out to us if you have any questions, here or through support.

Can we use Py3.9 on SG right now?
SG desktop is still on 3.7.11 and the python install that comes with It is still on 3.7, even after updating everything.

Hi @guilhermecasagrandi

Latest versions of toolkit core, apps, engines, frameworks and Python API are already supporting Python 3.9.

But Python version included in SG Desktop will only gets updated on November 1st 2022. This is to give enough time to our clients to get ready for the removal of Python 2.


Hi Warren,

question regarding desktop update,
all our DCC’s are 2.7 and our desktop is python 2.7
so if we update to python 3
will it still support all the dcc’s running 2.7 and 3.7
we are adding DCC’s which are running 3.7 and hence the qestion,

would be great to know


Based on his post @cloud all of the ShotGrid Toolkit tools are python 2/3 compatible. So you should be fine continuing to use DCCs that use py2.7 or 3.7. This change seems to only apply to the version of python ShotGrid Desktop will be running.

This does however mean that any custom hooks / apps you’ve created for ShotGrid Toolkit that may execute from ShotGrid Desktop need to support Python 3.9. You could check this now by running ShotGrid Desktop with the environment variable SHOTGUN_PYTHON_VERSION set to 3. If your config loads fine under these conditions it will certainly work when ShotGrid Desktop is released with 3.9 only support.

Hi Dan,

thanks for the info, and it seems to be working i ran shotgrid desktop with python set to 3,
it changed the desktop vesrion to 3 , and the DCC’s which were runing 2.7 works fine
