Load data for machine learning and deep learning
This section covers information about loading data specifically for ML and DL applications. For general information about loading data, see Load data into the Databricks Lakehouse.
Store files for data loading and model checkpointing
Machine learning applications may need to use shared storage for data loading and model checkpointing. This is particularly important for distributed deep learning.
Load tabular data
You can load tabular machine learning data from tables or files (for example, see CSV file). You can convert Apache Spark DataFrames into pandas DataFrames using the PySpark method
toPandas(), and then optionally convert to NumPy format using the pandas method
Prepare data for distributed training
This section covers two methods for preparing data for distributed training: Petastorm and TFRecords.
