Creates a new ReasoningEngine.

The Reasoning Engine will be an instance of the reasoning_engine that was passed in, running remotely on Vertex AI.

Sample src_dir contents (e.g. ./user_src_dir):

user_src_dir/
|-- main.py
|-- requirements.txt
|-- user_code/
|   |-- utils.py
|   |-- ...
|-- ...

To build a Reasoning Engine:

remote_app = ReasoningEngine.create(
    local_app,
    requirements=[
        # I.e. the PyPI dependencies listed in requirements.txt
        "google-cloud-aiplatform==1.25.0",
        "langchain==0.0.242",
        ...
    ],
    extra_packages=[
        "./user_src_dir/main.py", # a single file
        "./user_src_dir/user_code", # a directory
        ...

    gcs_dir_name: str = "reasoning_engine",
    sys_version: typing.Optional[str] = None,
    extra_packages: typing.Optional[typing.Sequence[str]] = None
) -> vertexai.reasoning_engines._reasoning_engines.ReasoningEngine

Updates an existing ReasoningEngine.

This method updates the configuration of an existing ReasoningEngine running remotely, which is identified by its resource name. Unlike the create function which requires a reasoning_engine object, all arguments in this method are optional. This method allows you to modify individual aspects of the configuration by providing any of the optional arguments. Note that you must provide at least one argument (except sys_version).

Parameters
Name	Description
`reasoning_engine`	`ReasoningEngineInterface` Optional. The Reasoning Engine to be replaced. If it is not specified, the existing Reasoning Engine will be used.
`requirements`	`Union[str, Sequence[str]]` Optional. The set of PyPI dependencies needed. It can either be the path to a single file (requirements.txt), or an ordered list of strings corresponding to each line of the requirements file. If it is not specified, the existing requirements will be used. If it is set to an empty string or list, the existing requirements will be removed.
`display_name`	`str` Optional. The user-defined name of the Reasoning Engine. The name can be up to 128 characters long and can comprise any UTF-8 character.
`description`	`str` Optional. The description of the Reasoning Engine.
`gcs_dir_name`	`CreateReasoningEngineOptions` Optional. The GCS bucket directory under `staging_bucket` to use for staging the artifacts needed.
`sys_version`	`str` Optional. The Python system version used. Currently updating sys version is not supported.
`extra_packages`	`Sequence[str]` Optional. The set of extra user-provided packages (if any). If it is not specified, the existing extra packages will be used. If it is set to an empty list, the existing extra packages will be removed.

Exceptions
Type	Description
`ValueError`	If `sys.version` is updated.
`ValueError`	If the `staging_bucket` was not set using vertexai.init.
`ValueError`	If the `staging_bucket` does not start with "gs://".
`FileNotFoundError`	If `extra_packages` includes a file or directory
`tha`	does not exist.:
`ValueError`	if none of `display_name`, `description`,
`requirements`
`specified.`
`IOError`	If requirements is a string that corresponds to a
`nonexisten`	file.:

Returns
Type	Description
`ReasoningEngine`	The Reasoning Engine that was updated.
