## TL;DR

Reporter iainmck found the workaround: force pip install protobuf==3.20.1, and two other users confirmed it fixed the import for them. The confirmed workaround is pip install protobuf==3.20.1 to pin the last working version.

## Steps

1. Importing stability-sdk in Colab started failing right after a protobuf release, because the new protobuf broke the DESCRIPTOR import the SDK relied on. Reporter iainmck found the workaround: force `pip install protobuf==3.20.1`, and two other users confirmed it fixed the import for them. Maintainer dmarx thanked the reporter and said the fix was being integrated into the package.

2. If the stability-sdk import suddenly breaks in Colab, check whether protobuf just released a new version, since a protobuf update broke the DESCRIPTOR import this package depends on. The confirmed workaround is `pip install protobuf==3.20.1` to pin the last working version. Multiple users verified this restores the import. Later SDK releases integrated the fix, so upgrading stability-sdk itself is the long-term answer.

## When to use

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: protobuf 3.20.1. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
