在plt.matshow()中指定cmap时出错

每次在调用sns.color_palete()时试图定义cmap时,我都会遇到一个错误。我认为这与调色板的定义有关,但我不确定:

colors = ["#1d4877", "#1b8a5a", "#fbb021", "#f68838", "#ee3e32"]
sns.set_palette(colors)

当我尝试设置它时:

plt.matshow(num1.corr(), cmap=sns.color_palette())
plt.show()

我得到以下错误:

我还试着调用sns.color_palete()函数,如下所示:

plt.matshow(num1.corr(), cmap=sns.color_palette(as_cmap=True))
plt.show()

并且它仍然产生相同的错误。
