From 501eb0719902bfbab6f1327c35f8ed2ad5caa7d6 Mon Sep 17 00:00:00 2001 From: Bob Kemp <5106328+bobkemp@users.noreply.github.com> Date: Wed, 5 Feb 2020 21:54:08 +0000 Subject: [PATCH 1/4] Allow experiment versions to be overridden by passing a string value. Allow experiment names to be empty, in which case no per-experiment subdirectory will be created and checkpoints will be saved in the directory given by the save_dir parameter. --- pytorch_lightning/loggers/tensorboard.py | 29 +++++++++++++++++++----- tests/test_logging.py | 13 +++++++++++ 2 files changed, 36 insertions(+), 6 deletions(-) diff --git a/pytorch_lightning/loggers/tensorboard.py b/pytorch_lightning/loggers/tensorboard.py index 48459cd889e33..4a738993e5462 100644 --- a/pytorch_lightning/loggers/tensorboard.py +++ b/pytorch_lightning/loggers/tensorboard.py @@ -47,6 +47,26 @@ def __init__(self, save_dir, name="default", version=None, **kwargs): self.tags = {} self.kwargs = kwargs + @property + def root_dir(self): + """ Parent directory for all tensorboard checkpoint subdirectories. + If the experiment name parameter is None or '', no experiment subdirectory is used + and checkpoint will be saved in save_dir/version_dir""" + if self.name is None or len(self.name) == 0: + return self.save_dir + else: + return os.path.join(self.save_dir, self.name) + + @property + def log_dir(self): + """ The directory for this run's tensorboard checkpoint.
