nvcc致命：安装cuda 9.1 + caffe + openCV 3.4.0时，不支持的GPU架构'compute_20'(nvcc fatal : Unsupported gpu architecture 'compute_20' while cuda 9.1+caffe+openCV 3.4.0 is installed)

 这一行： 
 
layout = (LinearLayout) findViewById(R.id.statsviewlayout);
 
 在当前的“contentview”中查找“statsviewlayout”ID。 现在你已经在这里设置： 
 
setContentView(new GraphTemperature(getApplicationContext()));
 
 而且我猜测新的“graphTemperature”并没有设置该ID的任何内容。 
 
 认为你可以用findViewById找到任何视图是一个常见的错误。 您只能找到一个位于XML中的视图（或由代码指定并给定一个id）。 
 
 因为您正在寻找的布局未找到，所以会抛出空指针 
 
layout.addView(buyButton);
 
 抛出异常。 
 
 补充：现在，如果你想从XML获得这个视图，你应该使用inflater： 
 
layout = (LinearLayout) View.inflate(this, R.layout.yourXMLYouWantToLoad, null);
 
 假设你在一个名为“yourXMLYouWantToLoad.xml”的文件中有你的线性布局 

This line:
 
layout = (LinearLayout) findViewById(R.id.statsviewlayout);
 
Looks for the "statsviewlayout" id in your current 'contentview'. Now you've set that here:
 
setContentView(new GraphTemperature(getApplicationContext()));
 
And i'm guessing that new "graphTemperature" does not set anything with that id.
 
It's a common mistake to think you can just find any view with findViewById. You can only find a view that is in the XML (or appointed by code and given an id).
 
The nullpointer will be thrown because the layout you're looking for isn't found, so
 
layout.addView(buyButton);
 
Throws that exception.
 
addition: Now if you want to get that view from an XML, you should use an inflater:
 
layout = (LinearLayout) View.inflate(this, R.layout.yourXMLYouWantToLoad, null);
 
assuming that you have your linearlayout in a file called "yourXMLYouWantToLoad.xml"
