fiftyone.core.utils.ResourceLimit

Context manager that allows for a temporary change to a resource limit exposed by the resource package.

Example:

   import resource
   import fiftyone.core.utils as fou

   with fou.ResourceLimit(resource.RLIMIT_NOFILE, soft=4096):
       # temporarily do things with up to 4096 open files

Args:
   limit: the name of the resource to limit. Must be the name of a
       constant in the ``resource`` module starting with ``RLIMIT``. See
       the documentation of the ``resource`` module for supported values
   soft (None): a new soft limit to apply, which cannot exceed the hard
       limit. If omitted, the current soft limit is maintained
   hard (None): a new hard limit to apply. If omitted, the current hard
       limit is maintained
   warn_on_failure (False): whether to issue a warning rather than an
       error if the resource limit change is not successful
