From da6681fe216418a45b76437cd2912ae09d571832 Mon Sep 17 00:00:00 2001 From: oesteban Date: Thu, 21 Sep 2017 16:47:16 -0700 Subject: [PATCH 01/83] [WIP,ENH] Revision to the resource profiler This PR revises the resource profiler with the following objectives: - Increase robustness (and making sure it does not crash nipype) - Extend profiling to all interfaces (including pure python) The increase of robustness will be expected from: 1. Trying to reduce (or remove at all if possible) the logger callback to register the estimations of memory and cpus. This could be achieved by making interfaces responsible or keeping track of their resources to then collect all results after execution of the node. 2. Centralize profiler imports, like the config or logger object so that the applicability of the profiler is checked only once. This first commit just creates one new module nipype.utils.profiler, and moves the related functions in there. --- doc/users/config_file.rst | 7 +- docker/files/run_examples.sh | 2 +- nipype/interfaces/base.py | 163 +------------------------ nipype/interfaces/utility/wrappers.py | 17 +-- nipype/pipeline/engine/nodes.py | 4 +- nipype/utils/config.py | 2 +- nipype/utils/filemanip.py | 2 +- nipype/utils/logger.py | 12 +- nipype/utils/profiler.py | 164 ++++++++++++++++++++++++++ 9 files changed, 187 insertions(+), 186 deletions(-) create mode 100644 nipype/utils/profiler.py diff --git a/doc/users/config_file.rst b/doc/users/config_file.rst index 7d55cc522d..1a1a550311 100644 --- a/doc/users/config_file.rst +++ b/doc/users/config_file.rst @@ -16,9 +16,10 @@ Logging *workflow_level* How detailed the logs regarding workflow should be (possible values: ``INFO`` and ``DEBUG``; default value: ``INFO``) -*filemanip_level* - How detailed the logs regarding file operations (for example overwriting - warning) should be (possible values: ``INFO`` and ``DEBUG``; default value: +*utils_level* + How detailed the logs regarding nipype utils like file operations + (for example overwriting warning) or the resource profiler should be + (possible values: ``INFO`` and ``DEBUG``; default value: ``INFO``) *interface_level* How detailed the logs regarding interface execution should be (possible diff --git a/docker/files/run_examples.sh b/docker/files/run_examples.sh index a23c27e76b..f23bc6f44c 100644 --- a/docker/files/run_examples.sh +++ b/docker/files/run_examples.sh @@ -12,7 +12,7 @@ mkdir -p ${HOME}/.nipype ${WORKDIR}/logs/example_${example_id} ${WORKDIR}/tests echo "[logging]" > ${HOME}/.nipype/nipype.cfg echo "workflow_level = DEBUG" >> ${HOME}/.nipype/nipype.cfg echo "interface_level = DEBUG" >> ${HOME}/.nipype/nipype.cfg -echo "filemanip_level = DEBUG" >> ${HOME}/.nipype/nipype.cfg +echo "utils_level = DEBUG" >> ${HOME}/.nipype/nipype.cfg echo "log_to_file = true" >> ${HOME}/.nipype/nipype.cfg echo "log_directory = ${WORKDIR}/logs/example_${example_id}" >> ${HOME}/.nipype/nipype.cfg diff --git a/nipype/interfaces/base.py b/nipype/interfaces/base.py index 19cf9ccaa6..c626328fde 100644 --- a/nipype/interfaces/base.py +++ b/nipype/interfaces/base.py @@ -44,22 +44,12 @@ File, Directory, DictStrStr, has_metadata, ImageFile) from ..external.due import due -runtime_profile = str2bool(config.get('execution', 'profile_runtime')) nipype_version = Version(__version__) iflogger = logging.getLogger('interface') FLOAT_FORMAT = '{:.10f}'.format PY35 = sys.version_info >= (3, 5) PY3 = sys.version_info[0] > 2 - -if runtime_profile: - try: - import psutil - except ImportError as exc: - iflogger.info('Unable to import packages needed for runtime profiling.
