使用matplotlib保存数字的问题

Question

使用matplotlib.pyplot.savefig使用循环不能节省超过57个数字。 我的代码的一部分：

    fig, ax = plt.subplots()
    ax.pie([views, calls, shows])
    ax.set_title(name_deal)
    ax.legend([f'Views: {views}', f'Calls: {calls}', f'Shows: {shows}'], loc='lower left')
    plt.savefig(f'C:/Users/User/PycharmProjects/diagramm/({id_deal}) {name_deal}.png', dpi=100)
    plt.close(fig)

保存57图时，我会收到一个错误：
