Labels on function decorator that are defined at runtime

Referring back to this thread: https://github.com/prometheus/client_python/issues/157
I wanted to know if there's a way to use the function decorator syntax with labels that will be instantiated at a later point? I need to fetch the label values from another service first. I am currently filling in some dummy values which will give me duplicated metrics:

inference_time_created{edge="EMPTY_SCOPE",line="EMPTY_SCOPE",module="EMPTY_SCOPE",plant="EMPTY_SCOPE",workload="EMPTY_SCOPE"} 1.6311126626366935e+09
inference_time_created{edge="ACTUAL_VALUE",line="ACTUAL_VALUE",module="ACTUAL_VALUE",plant="ACTUAL_VALUE",workload="ACTUAL_VALUE"} 1.6311126626709173e+09

So my question is if there's a way to not have the EMPTY_SCOPE metric on the endpoint.

This is the basic idea of what I'm doing:

scope_keys = ["plant", "edge", "line", "workload", "module"]
scope_values = ["EMPTY_SCOPE"] * 5
inference_time_created= Gauge('inference_time', 'How long (in seconds) does it take for an inference', scope_keys)
inference_time_created_labeled = inference_time_created.labels(*scope_values)

def set_metrics_scope(scope): # this function gets called later in the main code
    scope_values = scope
    inference_time_created_labeled = inference_time_created.labels(*scope_values)

@inference_time_created_labeled.time()
def inference():
    # do some calculations

Issue không xác định tệp nguồn hoặc bài kiểm thử nào. Hãy bắt đầu bằng cách lần theo lệnh gọi Gauge.labels và điểm vào .time() của decorator được sử dụng trong ví dụ; done phải cho phép cung cấp các giá trị nhãn về sau mà không để lộ metric EMPTY_SCOPE ban đầu.
