После этого я проверил следующее, не выдало ошибок:

import os
from mlflow import log_metric, log_param, log_artifact

Но когда я пытаюсь запустить веб-интерфейс пользователя, я получаю следующие ошибки:

$ mlflow ui

During handling of the above exception, another exception occurred:

Есть идеи, как мне это исправить?

Answer 1

Очевидно, мне пришлось установить модуль wheel в моей виртуальной среде. Я удалил виртуальную среду, заново создал ее, а затем установил модуль wheel:

pip install wheel

после этого pip install mlflow, а также mlflow ui успешно работали.
