Hi guys,
we were wondering, if anyone else is getting an error message while trying to run Dash with its compress option selected on a Python 3.14 docker image?
Observed phenomenon:
Unfortunately, this is an awkward one for us to investigate, since locally it works fine, but on an Docker deployment towards AWS it fails with the following error, even though dash[compress] is clearly being installed.
Error: To use the compress option, you need to install dash[compress]
Hypothesis:
We assume, either:
- That this is due to a lack of a required library(-ies) on the prescribed docker image by compliance/IT Sec internally. Which occurs with the
compression.zstdintegration added with Python 3.14. - Or dash[compress] uses gzip by default and it is not finding the gzip bindings where it expects them with >=Python3.14.x
Question:
Would anyone happen to know, which libs exactly are required for dash[compress] to work with Python 3.14.x? We tried quite some combinations, but to know success.
Sry for the vague description. Any advise would be greatly appreciated!
Best
Rob
