ax[0].plt.plot(first_layer_activation[0,:,0], cmap="viridis")

这是一个关于 Python 数据可视化的问题，我可以回答。这段代码是用来绘制第一层激活函数的可视化图像，其中 first_layer_activation 是一个三维张量，第一个维度是样本数，第二个维度是特征图的尺寸，第三个维度是特征图的通道数。plt.plot() 函数用来绘制第一个通道的特征图的可视化图像，cmap="viridis" 表示使用 viridis 颜色映射方案。

好的，你可以将这段代码修改为：

def draw_stats(self, vals, vals1, vals2, vals3, vals4, vals5, vals6, save_path):
        fig, axs = plt.subplots(4, 2, figsize=(16, 16))
        axs[0, 0].plot(vals)
        axs[0, 0].set_xlim(self.xlim)
        locs = axs[0, 0].get_xticks()
        locs[0] = self.xlim[0]
        locs[-1] = self.xlim[1]
        axs[0, 0].set_xticks(locs)
        axs[0, 0].use_sticky_edges = False
        axs[0, 0].set_title(f'Connected Clients Ratio')

        axs[1, 0].plot(vals1)
        axs[1, 0].set_xlim(self.xlim)
        axs[1, 0].set_xticks(locs)
        axs[1, 0].yaxis.set_major_formatter(FuncFormatter(format_bps))
        axs[1, 0].use_sticky_edges = False
        axs[1, 0].set_title('Total Bandwidth Usage')

        axs[2, 0].plot(vals2)
        axs[2, 0].set_xlim(self.xlim)
        axs[2, 0].set_xticks(locs)
        axs[2, 0].use_sticky_edges = False
        axs[2, 0].set_title('Bandwidth Usage Ratio in Slices (Averaged)')

        axs[3, 0].plot(vals3)
        axs[3, 0].set_xlim(self.xlim)
        axs[3, 0].set_xticks(locs)
        axs[3, 0].use_sticky_edges = False
        axs[3, 0].set_title('Client Count Ratio per Slice')

        axs[0, 1].plot(vals4)
        axs[0, 1].set_xlim(self.xlim)
        axs[0, 1].set_xticks(locs)
        axs[0, 1].use_sticky_edges = False
        axs[0, 1].set_title('Coverage Ratio')

        axs[1, 1].plot(vals5)
        axs[1, 1].set_xlim(self.xlim)
        axs[1, 1].set_xticks(locs)
        axs[1, 1].yaxis.set_major_formatter(FormatStrFormatter('%.3f'))
        axs[1, 1].use_sticky_edges = False
        axs[1, 1].set_title('Block ratio')

        axs[2, 1].plot(vals6)
        axs[2, 1].set_xlim(self.xlim)
        axs[2, 1].set_xticks(locs)
        axs[2, 1].yaxis.set_major_formatter(FormatStrFormatter('%.3f'))
        axs[2, 1].use_sticky_edges = False
        axs[2, 1].set_title('Handover ratio')

        plt.tight_layout()
        plt.savefig(save_path)
        plt.show()

这样就可以一张张输出图片了，你只需要传入一个保存路径参数 `save_path` 即可。

plt.title('Training Set')
plt.show()

plt.plot(test_predict_plot[len(train_predict) + time_steps * 2 + 1:])

plt.title('Test Set')
