TensorFlow - Azure Databricks

To make sure that your experiment logs are reliably stored, Azure Databricks recommends writing logs to DBFS (that is, a log directory under /dbfs/) rather than on the ephemeral cluster file system. For each experiment, start TensorBoard in a unique directory. For each run of your machine learning code in the experiment that generates logs, set the TensorBoard callback or filewriter to write to a subdirectory of the experiment directory. That way, the data in the TensorBoard UI will be separated into runs.
