1、0x00007FFFB973A388 处(位于 test.exe 中)有未经处理的异常: Microsoft C++ 异常:

      原因：很有可能就是在文件中的图片路径不正确。

2、在安装tensnorflow-gpu版本的出现Cannot uninstall 'Werkzeug'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

        在1、在终端输入命令：conda，输入：conda remove Werkzeug 就可以继续安装了pip3 install --upgrade tensorflow-gpu

3、var oUl = document.getElementById('ul1')//这里面的时候查找元素的时候使用getElementById //var aLi =                oUl.getElementsByTagName('li')//在使用在查找子元素的时候使用getElementsByTagNam

4 from sklearn.model_selection import train_test_split

后来在Anaconda Prompt里输入：conda list,发现sklearn版本是0.17.0，太低了 但是更新又出现问题。

解决方法：注意注解方面的语法发的规范化不然出错。
