.FileSystem¶
- class srlearn.system_manager.FileSystem[source]¶
BoostSRL File System
BoostSRL has an implicit assumption that it has access to a file system. At runtime it needs to both read and write with files. This object provides a view into the files needed, requests files from the operating system, and (most importantly) prepares and cleans up the file system at allocation/de-allocation time.
Notes
Ideally, each instance of a
srlearn.rdn.BoostedRDN
should have its own directory where it can operate independently. But this can be problematic and will often lead to duplicated data and other problems if multiple models are learned in parallel on the same database.Another option (which may be more suited to parallel tree learning) would be to store data in a single location, but write the log files and models to separate locations.
Examples
This first example may not appear to do much, but behind the scenes it is creating directories for each instance of
FileSystem
, and removing them uponexit()
.>>> from srlearn.system_manager import FileSystem >>> systems = [] >>> for _ in range(5): ... systems.append(FileSystem())
