我在运行 http://127.0.0.1:5000/iris/1/1/1/1 时遇到问题。它不断收到内部服务器错误。我不知道为什么,它一直在这样做。我尝试了很多方法,但仍然没有奏效。它一直在说“modulenotfounderror: no module named 'sklearn.linear_model.logistic' 。”有没有办法解决这个问题。

答案 0 :(得分:0)
查看scikit-learn的版本,可能是0.21.x。升级版本。
这是 scikit-learn 稳定版: https://github.com/scikit-learn/scikit-learn/tree/master/sklearn/linear_model
