"""Load runs from a directory; recursively walks subdirectories.
If path doesn't exist, no-op. This ensures that it is safe to call
`AddRunsFromDirectory` multiple times, even before the directory is made.
If path is a directory, load event files in the directory (if any exist) and
recursively call AddRunsFromDirectory on any subdirectories. This mean you
can call AddRunsFromDirectory at the root of a tree of event logs and
TensorBoard will load them all.
If the `EventMultiplexer` is already loaded this will cause
the newly created accumulators to `Reload()`.
Args:
path: A string path to a directory to load runs from.
name: Optionally, what name to apply to the runs. If name is provided
and the directory contains run subdirectories, the name of each subrun
is the concatenation of the parent name and the subdirectory name. If
name is provided and the directory contains event files, then a run
is added called "name" and with the events from the path.
Raises:
ValueError: If the path exists and isn't a directory.
Returns:
The `EventMultiplexer`.
