Updates multiple derived logs, identified either by a direct list of derived IDs or by get_logs–style filters. If ‘referenced_logs’ is provided, we delete all existing derived logs for each (log_event_id, key) group and re-insert new ones referencing the new base logs. Finally, we recompute them.

The context parameter can be:

  • A string: Uses the string as the context name with default values (description=None, is_versioned=False)
  • An object: Uses the object’s name, description, and is_versioned properties

​
Authorizations

​
Authorization
string
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

​
Body

​
project
string
required

Name of the project these derived logs belong to.

​
context
any | string | null

Optional context path to update for the logs. Can use ’/’ for nested contexts (e.g. ‘training/batch1’). Can be a string (which will be interpreted with description=None and is_versioned=False) or a ContextCreateRequest object.

​
target_derived_logs
array | object
required

The derived logs to update, either as a list of derived_log IDs or as a set of arguments for the get_logs endpoint.

​
key
string | null

New key name for the derived entries

​
equation
string | null

New equation for computing derived values

​
referenced_logs
object | null

Optional new referenced logs to use for computation. Can be specified either as a list of log IDs or as a set of arguments for the get_logs endpoint.
