希望你做得很好：
运行tensorflow代码，在命令提示符中显示：
2020-04-19 19:47:33.130484: I tensorflow/core/profiler/internal/gpu/cupti_tracer.cc:1378] CUPTI activity buffer flushed

有问题吗？如果我担心的话，我在GPU上使用tensorflow。
谢谢，Gabriel
它们只是以I为前缀的Information消息，否则，如果是错误消息，则会以E或W为前缀进行警告。
例如，在下面的错误跟踪中，有一些以I为前缀的Information消息和以E为前缀的error消息。
