Unable to register feature store in demo notebook

[brazils]

I am trying to step through the demo notebook in ml/feature_store/notebooks/customer_demo/Basic_Feature_Demo.ipynb

I run this block in the notebook

fv = FeatureView(
    name="WINE_FEATURES", 
    entities=[entity], 
    feature_df=feature_df, 
    desc="wine features"
)
fs.register_feature_view(
    feature_view=fv, 
    version="V1", 
    refresh_freq="1 minute", 
    block=True
)

This is the output:

/Users/<redacted>/projects/snowflake-ml-python/snowflake/ml/feature_store/feature_store.py:1062: UserWarning: Dynamic table: `FEATURE_STORE_BASIC_FEATURE_NOTEBOOK_DEMO.AWESOME_FS_BASIC_FEATURES.WINE_FEATURES$V1` will not refresh in INCREMENTAL mode. It will likely incurr bigger computation cost. The reason is: Query contains the function 'SEQ8', but change tracking is not supported on queries with non-deterministic functions.
  warnings.warn(

Then running the next block

# Examine the FeatureView content
fs.read_feature_view(fv).show()

I get this error:

Hi @brazils , the reason you are getting this error is because fv is not registered. To make it work, simply:fv = fs.register_feature_view(...). BTW, I believe you're running out-of-date notebook against newer code. This notebook has been updated a while ago.

Hi @brazils have you had the chance to try out the approach @sfc-gh-wezhou suggested above?

I am closing this stale issue. If you have any problem, please re-open it.
