我正在使用 ipython 笔记本。我正在使用 python 3.5 。运行如下所示的程序时，我收到“没有名为“fig_code”的模块”错误。

#Code
from sklearn import neighbors, datasets

iris = datasets.load_iris()
X, y = iris.data, iris.target

knn = neighbors.KNeighborsClassifier(n_neighbors=5, weights='uniform')

knn.fit(X, y)

X_pred = [3, 5, 4, 2]
result = knn.predict([X_pred, ])

print(iris.target_names[result])

print(iris.target_names)

print(knn.predict_proba([X_pred, ]))

from fig_code import plot_iris_knn
plot_iris_knn()

我收到的错误如下

ImportError                               Traceback (most recent call last)

我尝试使用“pip install Fig_code”安装Fig_code，但收到此错误
