TypeError: 'module' object is not callable 。如何解决这个问题呢

Question

y_train = y_train.reshape(-1,)

    y_train[:5]
    
    y_test = y_test.reshape(-1,)
    
    nwclasses= classes
    nwclasses = ["airplane","automobile","bird","cat","deer","dog","frog","horse","ship","truck"]
    def plot_sample(X, y, index):
        plt.figure(figsize = (15,2))
        plt.imshow(X[index])
        plt.xlabel(classes[y[index]]) 
    plot_sample(X_train, y_train, 1)

**TypeError Traceback（最近一次调用最后一次） 在 ----> 1 plot_sample(X_train, y_train, 1)

TypeError: 'module' object is not callable**

Answer 1

figure 是 matplotlib 中的一个模块，我们用 figure.Figure 类代替：

import matplotlib
matplotlib.figure.Figure(figsize = (15,2))
