Blog Branch Error

[Lord-V15]

When I try to run the script, I had to solve tf v1 issues by using tf.compat.v1 everywhere. Still, when I create the index it shows the error :
elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'No handler for type [dense_vector] declared on field [title_vector]')
I want to understand why this error is being shown.

We need the default build flavor for embeddings to work. As you can see below, mine was an OSS build :

@jtibshirani can you add this information about which build_flavor is needed for this script to run in the readme as it is very difficult to find the issue and it's solution online.
