在Python中绘制累积增益曲线（ModuleNotFoundError：没有名为'scikitplot'的模块）

Question

我是数据科学和python的新手。我试图使用scikitplot绘制我在Spyder（Python 3.6）中构建的模型的累积增益曲线。但是，它一直返回错误：ModuleNotFoundError：没有名为'scikitplot'的模块。

见下文：

import scikitplot as skplt
Traceback (most recent call last):
  File "<ipython-input-17-1b8f6cd7465e>", line 1, in <module>
    import scikitplot as skplt
ModuleNotFoundError: No module named 'scikitplot'

我尝试在anaconda提示符上使用以下内容：

pip install -U scikit-learn scipy matplotlib

和

pip3 install -U scikit-learn scipy matplotlib

但是，这些都没有奏效。结果anaconda提示：

(base) C:\Users\johndoe>pip install -U scikit-learn scipy matplotlib

你安装了Matplotlib吗？ Scikit-plot取决于Scikit-learn和Matplotlib
