…es quantized - Added a new parameter 'version' on runTauIdMVA, used on DPFIsolation - Changes on DeepTauId to reduce memory consumption
…read and reduce the memory consuption - Creation of class DeepTauCache in DeepTauBase, in which now is created graph and session - Implementation of two new static methods inside the class DeepTauBase: initializeGlobalCache and globalEndJob. The graph and DeepTauCache object are created now inside initializeGlobalCache
TauWPThreshold class parses WP cut string (or value) provided in the python configuration. It is needed because the use of the standard StringObjectFunction class to parse complex expression results in an extensive memory usage (> 100 MB per expression).
- Implementation of global cache to avoid reloading graph for each thread - Creation of two new static methods inside the class DeepTauBase: initializeGlobalCache and globalEndJob. The graph and DeepTauCache object are created now inside initializeGlobalCache. The memory consumption of initializeGlobalCache for the original, quantized and files that are load using memory mapping method are in the memory_usage.pdf file - Implemented configuration to use new training files quantized, and set them as default - Implementation of configuration for load files using memory mapping. In our case there wasn't any improvement, respect at the memory consumption of this method, respect the quantized files, so this is not used, but set for future training files - General code review and cleaning.
