Python Pyplot投影不'；t允许数据：numpy.float64错误

我使用的是Mac和HighSierra、python 2.7和Ipython 5.5.0

在pyplot中使用任何类型的投影（如aitoff、polar、hammer等）时，除非图形为空，否则无法显示或保存该图形。即使我只是尝试添加网格，我已经有问题了（当然，数据也有问题）

将返回：

最后，我尝试了更新所有内容，并按照其他一些帖子中的建议对这个numpy错误进行了降级，但没有任何效果。

从matplotlib页面上看，坚持函数签名似乎是个好主意

在这里，您可能需要一个子地块，因此

plt.subplot(111,projection="aitoff")

---

我明白了：解决方案是安装numpy 1.11.0，但由于我的计算机中安装了几次，所以它无法工作。我不得不删除其他版本（如果通过pip安装，这可以手动完成，只需删除文件），或者更改环境以使用我想要的numpy版本。

您使用的是哪个版本的matplotlib？我使用的是matplotlib 2.1.2，我对此表示怀疑。在matplotlib 2.1.2中，引起错误的函数位于代码中第1500行附近，而您在第1700行附近显示它。这是我键入help（matplotlib）时得到的结果。无论如何，我发现了，我安装了2台numpy，它在电脑的其他地方使用了1.14。现在我将环境更改为使用numpy 1.11.0（也许matplotlib就是这样的）。谢谢你的帮助！

subplot(nrows, ncols, index, **kwargs)
#
subplot(3_digit_number, **kwargs)

plt.subplot(111,projection="aitoff")
