Python测试由于TCL误差而在Matplotlib子图上随机失败

Question

由于TCL错误，我在plt.subplots上失败了测试。这是测试，并在上升错误的行中：

    def test_plot_epoch_segmentation():
        """Test segmentation plots for epochs."""
        n_clusters = 4
        labels = np.random.choice(
            [-1, 0, 1, 2, 3], (len(epochs), epochs.times.size)
        )
    
        plot_epoch_segmentation(labels, epochs, n_clusters)
        plt.close("all")
    
        # provide ax
        f, ax = plt.subplots(1, 1)
        plot_epoch_segmentation(labels, epochs, n_clusters, axes=ax)
        plt.close("all")
    
        # provide cbar_ax
>>      f, cbar_ax = plt.subplots(1, 1)

请注意，上面的4行...相似的plt.subplots被调用，并且不会升高。毫无疑问，这是提出的错误：
