There appears to be a breaking change in Redis 6.3.0 (or a similar version, perhaps 6.0.0?) that causes this error:

___ ERROR collecting tests/unit/connectors/memory/redis/test_redis_store.py ____
ImportError while importing test module '/Users/runner/work/semantic-kernel/semantic-kernel/python/tests/unit/connectors/memory/redis/test_redis_store.py'.
Hint: make sure your test modules/packages have valid Python names.

your application relies on modules like redis.commands.search.indexdefinition, you may encounter compatibility issues with versions 5.0 and above due to structural changes in the package looks like . To maintain compatibility with such modules, hence we can try with redis-py version 4.5.5.
