• Feature: allow to pass unparsed commandline string to ex.run_commandline.

• Feature: improved stdout/stderr capturing: it now also collects non-python

  that name.

• API Change: Experiment.run_command is deprecated in favor of run, which now

  also takes a command_name parameter.

  preinstalled versions of six.

• Bugfix: fixed a problem when trying to set the loglevel to DEBUG
• Bugfix: type conversions from None to some other type are now correctly ignored

• Bugfix: fixed a problem with stdout capturing breaking tools that access

0.6.10 (2016-08-08)

• Bugfix: fixed a problem when trying to set the loglevel to DEBUG
• Bugfix: fixed a random crash of the heartbeat thread (see #101).

• Feature: added --force/-f option to disable errors and warnings concerning

  suspicious changes. (thanks to Yannic Kilcher)

• Feature: experiments can now be run in Jupyter notebook, but will fail with

  an error by default, which can be deactivated using interactive=True

• Feature: added support for adding a captured out filter, and a filter that

  and applies backspaces and linefeeds before saving like a terminal would. (thanks to Kevin McGuinness)

0.6.9 (2016-01-16)

• Bugfix: fixed support for @ex.named_config (was broken by 0.6.8)

  added unused config entries

• Feature: Added automatic conversion of pandas datastructures in the

  custom info dict to json-format in the MongoObserver.

• Feature: Fail if a new config entry is added but it is not used anywhere

• Feature: Added a warning if no observers were added to the experiment.

  Added also an unobserved keyword to commands and a --unobserved commandline option to silence that warning

• Feature: Split the debug flag -d into two flags: -d now only disables

  stacktrace filtering, while -D adds post-mortem debugging.

• API change: renamed named_configs_to_use kwarg in ex.run_command

  method to named_configs

• API change: changed the automatic conversion of numpy arrays in the

  MongoObserver from pickle to human readable nested lists.

• Bugfix: Fixed a problem with debugging experiments.
• Bugfix: Fixed a problem with numpy datatypes in the configuration

• Bugfix: More helpful error messages when using return or yield in a

  config scope

• Bugfix: Be more helpful when using -m/--mongo_db and pymongo is not installed

0.6.7 (2015-09-11)

• Bugfix: fixed an error when trying to add a mongo observer via command-line

• Feature: added -c/--comment commandline option to add a comment to a run

• Feature: added -b/--beat_interval commandline option to control the

  rate of heartbeat events

• Feature: introduced an easy way of adding custom commandline options

0.6.5 (2015-08-28)

• Feature: Support @ex.capture on methods (thanks to @Treora)

• Bugfix: fixed an error that occurred when a dependency module didn't have a

  the '__file__' attribute

0.6.4 (2015-06-12)

• Bugfix: fixed a problem where some config modification would be displayed as

  added if there where multiple ConfigScopes involved

• Bugfix: fixed a problem with tracking typechanges related to None-type
• Bugfix: fixed a crash related to MongoObserver being an unhashable type

• Bugfix: added back setslice and delslice methods to DogmaticList for

  python 2.7 compatibility

0.6.3 (2015-04-28)

• Bugfix: fixed a bug in the mongo observer that would always crash the final

  save

• Bugfix: automatic detection of local source files no longer wrongly detects

  non-local files in subdirectories.

0.6.2 (2015-04-16)

• Bugfix: fixed crash when using artifacts
• Bugfix: added resources are now saved immediately

0.6.1 (2015-04-05)

• Bugfix: fixed a crash when some numpy datatypes were not present

  (like numpy.float128)

• Bugfix: Made MissingDependencyMock callable so it would also correctly

  report the missing dependency when called

• Bugfix: MongoObserver would just crash the experiment if the result or the

  info are not serializable. Now it warns and tries to alter problematic entries such that they can be stored.

0.6 (2015-03-12)

• Feature: With the new add_artifact function files can be added to a run

  That will fire an artifact event and they will also be stored in the database by the MongoObserver.

• Feature: Files can be opened through the experiment using open_resource,

  which will fire a resource_event and the file is automatically saved to the database by the MongoObserver

• Feature: Collections used by the MongoObserver can now have a custom prefix

• Feature: MongoObserver saves all sources as separate files to the database

  using GridFS

• Feature: Sources and package dependencies can now also be manually added

• Feature: Automatically collect imported sources and dependencies also from

  ingredients

• Feature: added print_dependencies command

• Feature: With the --debug flag Sacred now automatically enters

  post-mortem debugging after an exception.

• Feature: Allow to specify a config file (json, pickle or yaml) on the

  command-line using with.

• Feature: Normal dictionaries can now be added as configuration to experiments

  using the new add_config method.

• Feature: MongoObserver now tries to reconnect to the MongoDB if connection

  is lost, and at the end of an experiment writes the entry to a tempfile if the reconnects failed.

• Bugfix: Invalid config keys could crash the MongoObserver or the

  print_config command. Now they are checked at the beginning and an exception is thrown.

• Bugfix: fixed coloring of seeds modified by or entries added by named configs
• Documentation: greatly improved the examples and added them to the docs

0.5.2 (2015-02-09)

• Bugfix: processor name was not queried correctly on OSX

0.5.1 (2014-10-07)

  longer marked as modified by print_config

• Optimization: special arguments _rnd and _seed are now only generated

  if needed

• Bugfix: undocumented defective feature **config removed from

  captured functions

• Bugfix: fixed bug where indentation could lead to errors in a ConfigScope

• Bugfix: added warning when attempting to overwrite an ingredient

  and it is ignored by Sacred

• Bugfix: fixed issue with synchronizing captured out at the end of the run.

  (before up to 10sec of captured output could be lost at the end)

• Bugfix: modifications on seed were not marked correctly by print_config

• Bugfix: changes to seed in NamedConfig would not correctly affect Ingredients

  Note that in order to fix this we removed the access to seed from all ConfigScopes. You can still set the seed but you can no longer access it from any ConfigScope including named ones. (Of course this does not affect captured functions at all.)

• Style: Lots of pep8 and pylint fixes

0.5 (2014-09-22)
