【问题描述】：
这个简单的 Python 代码显示了 Ascii 艺术，取自以下 quora 回复：https://qr.ae/TWNB4S。我通过 python.org 的独立安装程序和 anaconda 套件在我的 Windows 10 笔记本电脑上安装了 Python 版本 3.7.3。该代码在通过 anaconda 启动的 Jupyter notebook 上运行良好。但是当我通过 pycharm IDE 运行相同的代码时，我得到了与 SSL 相关的错误。
我在网上搜索了此错误，但在我的 Windows 10 python 3.7.3 安装中找不到解决此问题的方法。但它在我的 Anaconda python 3.7.3 版本上运行良好。那么有没有办法克服这个错误？ 代码：
import ascii
output = ascii.loadFromUrl("https://i.dailymail.co.uk/i/pix/2015/09/01/18/2BE1F43200000578-0-image-a-17_1441127603656.jpg")
print(output)
通过 Pycharm IDE 运行上述代码时的错误：
