Python - plt.tight_layout() TypeError：“模块”对象不可调用

Question

我正在尝试运行以下代码

import matplotlib as plt

def plot_filters(layer, x, y):

    filters = layer.get_weights()
    fig = plt.figure.Figure()

    for j in range(len(filters)):
        ax = fig.add_subplot(y, x, j+1)
        ax.matshow(filters[j][0], cmap = plt.cm.binary)
        plt.xticks(np.array([]))
        plt.yticks(np.array([]))

    plt.tight_layout()
    return plt

plot_filters(model.layers[0], 8, 4)

当运行这个时，我收到'module' object is not callable并且它正在引用该plt.tight_layout()行。不知道如何称呼这个。它存在于 matplotlib 包中。

任何帮助将不胜感激！

谢谢

您已将matplotlib模块本身导入为plt，您应该将pyplot模块导入plt为：

import matplotlib.pyplot as plt
import matplotlib.cm as cm

def plot_filters(layer, x, y):

    filters = layer.get_weights()
    fig = plt.figure()

    for j in range(len(filters)):
        ax = fig.add_subplot(y, x, j+1)
        ax.matshow(filters[j][0], cmap = cm.binary)
        plt.xticks(np.array([]))
        plt.yticks(np.array([]))

    plt.tight_layout()

plot_filters(model.layers[0], 8, 4)
