### Method Details

`create(parent, body, x__xgafv=None)`

    Creates a model which will later contain one or more versions.

    You must add at least one version before you can request predictions from
    the model. Add versions by calling
    [projects.models.versions.create](/ml-engine/reference/rest/v1/projects.models.versions/create).

    Args:
      parent: string, Required. The project name. (required)
      body: object, The request body. (required)
        The object takes the form of:

`list(parent, pageToken=None, x__xgafv=None, pageSize=None, filter=None)`

    Lists the models in a project.

    Each project can contain multiple models, and each model can have multiple
    versions.

    If there are no models that match the request parameters, the list request
    returns an empty response body: {}.

    Args:
      parent: string, Required. The name of the project whose models are to be listed. (required)
      pageToken: string, Optional. A page token to request the next page of results.

    You get the token from the `next_page_token` field of the response from
    the previous call.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
      pageSize: integer, Optional. The number of models to retrieve per "page" of results. If there
    are more remaining results than this number, the response message will
    contain a valid value in the `next_page_token` field.

    The default value is 20, and the maximum page size is 100.
      filter: string, Optional. Specifies the subset of models to retrieve.

    Returns:
      An object of the form:

      updateMask: string, Required. Specifies the path, relative to `Model`, of the field to update.

    For example, to change the description of a model to "foo" and set its
    default version to "version_1", the `update_mask` parameter would be
    specified as `description`, `default_version.name`, and the `PATCH`
    request body would specify the new value, as follows:

          "defaultVersion": {
            "name":"version_1"

    Currently the supported update masks are `description` and
    `default_version.name`.

`testIamPermissions(resource, body, x__xgafv=None)`

    Returns permissions that a caller has on the specified resource.
    If the resource does not exist, this will return an empty set of
    permissions, not a NOT_FOUND error.

    Note: This operation is designed to be used for building permission-aware
    UIs and command-line tools, not for authorization checking. This operation
    may "fail open" without warning.

    Args:
      resource: string, REQUIRED: The resource for which the policy detail is being requested.
    See the operation documentation for the appropriate value for this field. (required)
      body: object, The request body. (required)
        The object takes the form of:

    { # Request message for `TestIamPermissions` method.
        "permissions": [ # The set of permissions to check for the `resource`. Permissions with
            # wildcards (such as '*' or 'storage.*') are not allowed. For more

        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Response message for `TestIamPermissions` method.
        "permissions": [ # A subset of `TestPermissionsRequest.permissions` that the caller is
