When testing this code ( fe.score_batch( df=dataset.drop("Target").limit(10), model_uri=f"models:/{model_name}/{mv.version}", ) .select("prediction") .limit(10) .display() ) I get the error: “MlflowException: The...
I just discovered what I believe is a bug in Feature Store. The expected value (of the "value" column) is 'NULL' but the actual value is "a". If I instead change the format to timestamp of the "date" column (i.e. removes the .date() in the generation...
Thank you for answering. Yes, that is also what I figured out. In other words the lookback_window argument only works when using timestamp format for the primary key. I cannot see that this behavior is described in the documentation.
Hi,I am trying to deploy my model which was logged by featureStoreEngineering client as a serving endpoint in Databricks. But I am facing following error: The Databricks Lookup client from databricks-feature-lookup and Databricks Feature Store clie...
Hi @damselfly20 unfortunately I can't help much with that as I've never worked with RAGs. Are you sure it's the same error though? @NaeemS's and my errors seems to be Java related and yours MLflow related.
Hi, For the model serving latency graph what is p50 and p99? I only have one model i am serving on this endpoing so im surprised to see two models being tracked
If im not mistaken this refers to 50% of responses and 99% responses and averages accordingly for the metrics? @s_park @Sujitha @Debayan
Hello, I am trying to replicate this motebook in my environment: mlflow-end-to-end-example - Databricks However, I am getting the following error when I run "import mlflow": "TypeError: bases must be types"How can I solve this issue? Thank you, Tanji...
Hello @tanjil Thank you for contacting databricks community support. Could you check what version of protobuf you have? If you are using 10.4 ML cluster, the MLflow 1.x is not compatible with protobuf 4.x. The default version of protobuf in MLR 10...
I am getting the following error while saving a delta table in the feature storeWARNING databricks.feature_store._catalog_client_helper: Failed to record data sources in the catalog. Exception: {'error_code': 'INVALID_PARAMETER_VALUE', 'message': 'To...
Hi @yorabhir, Verify how many sources you’re trying to record in the catalog. If it exceeds 100, you’ll need to reduce the number of sources.Ensure that the feature table creation process is correctly configured. In your code snippet, you’re creatin...
Hi, I am using multiple feature stores in my workflow using feature lookups. In my logged pipeline, I have several stages, including Assembler, Standard Scaler, Indexer and then Model. However, I am facing an issue during inference using the `score b...
Hi @NaeemS , Handling null values in feature stores is crucial to ensure robustness and reliability in your machine learning pipelines. Let’s explore some strategies to address this issue: Custom Transformer Stage: You’ve already considered addin...
Hi Everyone. I have a couple of questions about the feature store log model and score batch. After you log a model with the feature store then use fs.score_batch is it possible to pass the env_manager to predict with the same env as training as descr...
I also like to know if that works.
I am trying to track the lineage of model and tables using the FeatureEngineeringClient. The table lineage shows the relevant tables and notebooks but the model lineage shows only the model. No notebook and tables. here is my code fe = FeatureEngine...
ok I realized something else. That although I used FeatureEngineeringCient, MLflow model artifact suggest I used FeatureStoreClient. Please see attachment.
I have a pyfunc model that I can use to get predictions. It takes time series data with context information at each date, and produces a string of predictions. For example:The data is set up like below (temp/pressure/output are different than my inpu...
I have the same question. I've decided to look for alternative Feature Stores as this makes it very difficult to use for time series forecasting.
Our small team has just finished the data preparation phase of our project and started data analysis in Databricks. As we go deeper into this field, we're trying to understand the distinctions and appropriate uses for a Feature Store versus a Unity C...
Hi @Northp Good day!1.) A Feature Store is a centralized repository that enables data scientists to find and share features, ensuring that the same code used to compute the feature values is used for model training and inference. It is particularly...
Can Databricks feature tables be stored outside of DBFS?
Yes, Databricks feature tables can be stored outside of Databricks File System (DBFS). You can store your feature tables in external storage systems such as Amazon S3, Azure Blob Storage, Azure Data Lake Storage, or Hadoop Distributed File System (HD...
I've created a dataset that I want to create a feature store table for. I created a database in my dev unity catalog to store the feature tables, but each time I try to create the table I get this error:ValueError: Invalid catalog 'dev' or schema 'fe...
Hello,The error message suggests that there might be an issue with the catalog or schema name you are using when trying to create the feature store table. Here are a few tips to help you troubleshoot this problem:Verify the catalog and schema names: ...
When I try to serve a model stored with FeatureStoreClient().log_model using the feature-store-online-example-cosmosdb tutorial Notebook, I get errors suggesting that the primary key schema is not configured properly. However, if I look in the Featur...
Hello @Thomas Michielsen , this error seems to occur when you may have created the table yourself. You must use publish_table() to create the table in the online store. Do not manually create a database or container inside Cosmos DB. publish_table()...
Could someone explain the practical advantages of using a feature store vs. Delta Lake. apparently they both work in the same manner and the feature store does not provide additional value. However, based on the documentation on the databricks page, ...
