We are using a distributed configuration and one of the artist is having this issue loading a project which works for others

The error is the following:

No module named ‘tank_vendor.six.moves’

No idea how to solve this, have deleted local cache and local bundles, also reinstalling SG desktop

Any ideas to solve this?

The latest tk-core updates have moved around a bunch of things relating to third party libraries and also removed support for six as everything is now python 3 only.

It somehow might have found it’s way to that configuration?

We were able to reproduce this issue after updating FPT desktop to v3.0.0.

To sum up, if you have a zero config site configuration or pipeline site conifg up to date and a project configuration with an older tk-core, it will break with your error. Try updating the project’s core version to match the site configuration (it might be the latest)

Hi @kuri, I hope you were able to figure out the issue on your project.

This is most likely an issue with Python 3.13 loading an older version of tk-core which is not compatible with Python 3.13 (Python 3.13 is unable to load the six module).

We recently updated the “IMPORTANT - Toolkit Configuration Version Requirement” section of the FlowPT Desktop v3.0.0 Release Notes. You might find useful information there about your issue.

Uodated the core version for project configuration, now im able to launch project apps with latest desktop version
