Hydra 1.2.0

1.2.0 (2022-05-17)

Bug fixes

• hydra.runtime.choices is now updated correctly during multi-run (#1882)
• hydra.verbose=True now works with multirun. (#1897)
• Fix a resolution error occurring when a nested class is passed as a _target_ keyword argument to instantiate (#1914)
• It is now possible to pass other callable objects (besides functions) to hydra.main. (#2042)

New features

• Add support to Hydra's instantiation API for creation of functools.partial instances via a _partial_ keyword. (#1283)
• Support defining basic sweeping in input config. (#1376)
• Improve error message with more context when an omegaconf exception occurs during the config merge step. (#1697)
• Add --experimental-rerun command-line option to reproduce pickled single runs (#1805)
• Add experimental Callback for pickling job info. (#2092)
• Implement tab completions for appending to the defaults list (+group=option) and deleting from the defaults list (~group). (#1841)
• Enable the use of the pipe symbol | in unquoted strings when parsing command-line overrides. (#1850)
• Support for Python 3.10 (#1856)
• Improve clarity of error messages when hydra.utils.instantiate encounters a _target_ that cannot be located (#1863)
• The instantiate API now accepts ListConfig/list-type config as top-level input. (#1950)
• Improve error messages raised in case of instantiation failure. (#2099)
• Add callback for logging JobReturn. (#2100)
• Support disable changing working directory at runtime. (#910)
• Support setting hydra.mode through config. (#394)

Behavior changes

• The antlr version requirement is updated from 4.8 to 4.9, to align better with current antlr versions
• If user code raises an exception when called by instantiate, raise an InstantiateError exception instead of an instance of the same exception class that was raised by the user code. (#1911)
• Remove support for deprecated arg config_loader to Plugin.setup, and update signature of run_job to require hydra_context. (#1953)

The remaining changes are protected by the new version_base support, which allows one to either configure Hydra to support older setups / config, or configure Hydra to use the following more modern defaults:

• Remove deprecated "old optional" defaults list syntax (#1952)
• Remove support for the legacy hydra override syntax (see deprecation notice). (#2056)
• Remove support for old hydra.experimental.{compose,initialize} interface
• Remove support for _name_ and _group_ from package header (see deprecation notice)
• Remove support for legacy default list interpolation format (see deprecation notice)
• Remove support for TargetConf class
• Remove support for strict flag from compose API (see deprecation notice)
• Remove support for ".yml" extensions, requiring ".yaml" instead.
• Default to not changing the working directory at runtime. Use hydra.job.chdir=True to reinstate old behavior.
• Default to not adding any directory to the config path. (see config_path options)
