Question

我有一个使用matplotlib和python创建和保存绘图的代码。代码在我的主管的笔记本电脑上完美运行，他的主管有matplotlib 1.1.1。但是，尽管我有更新版本的matplotlib（1.3.1），但在执行此命令时出现以下错误：

plt.savefig("outputs/" + run_uuid +".pdf", facecolor='white', bbox_inches='tight', pad_inches=0.0)

我在该命令上获得以下Traceback：

Traceback (most recent call last):

    plt.savefig("outputs/" + run_uuid +".pdf", facecolor='white', bbox_inches='tight', pad_inches=0.0)

    'to_rgba: Invalid rgba arg "%s"\n%s' % (str(arg), exc))
ValueError: to_rgba: Invalid rgba arg "None"
to_rgb: Invalid rgb arg "None"
cannot convert argument to rgb sequence

我在网上找不到任何有用的错误。你知道我做错了吗？

我也尝试重写这个

plt.savefig("outputs/" + run_uuid +".pdf", facecolor='white', bbox_inches='tight', pad_inches=0.0)

到此：

plt.savefig("outputs/" + run_uuid +".pdf")

但没有任何进展

我认为理由是facecolor没有“白色”的价值。

从the following link开始，脸部颜色设置中不存在“白色”。

如果只使用plt.savefig（“你的路径”）怎么办？我认为默认背景颜色应该是白色。

Python“无效的rgb arg”无“”
