train[:, -1]， 是说对train这个二维的数据，逗号分隔开的前面的":"是说取全部的行，逗号后面的-1是说取最后一列。 如果换成一维数组会容易理解，比如list[:] 以及list[-1]。
我们知道，在pytorch中，模型有两种模式可以设置，一个是train模式、另一个是eval模式。. model.train ()的作用是启用 Batch Normalization 和 Dropout。. 在train模式，Dropout层会按照设定的参数p设置保留激活单元的概率，如keep_prob=0.8，Batch Normalization层会继续计算数据的mean和 ...

2009年7月18日 · Senior Member. Hampshire UK. English. Jul 18, 2009. #6. I would say "I am on the train" and "I am on the bus". I would also most likely say "I got into the taxi" and "I got out of the taxi". Notice the definite article (the) each time. I am not aware of any 'rule' about this.
2010年3月15日 · Mar 15, 2010. #2. "Go into the train" for me insinuates brutally colliding with it. However, "I went in a train" (especially said by someone possibly excited about the new experience of being inside a carriage) sounds correct, but "to go by train" or "to go on a train" are in standard use. EDIT: Sorry I think I misread your question.
2010年9月3日 · With the train=teach meaning, "in" is used with methods and techniques, essentially abstract concepts. However, if a new machine has been installed and workers need to be trained how to use it, they are trained "on the new machine". This isn't the only option, and they could instead be trained "in using the new machine", since "using the new ...
2020年5月31日 · Coventry, UK. English UK Southern Standard English. May 31, 2020. #4. You need the article with "journey" because you're talking about a specific one - the one from Moscow to Beijing which takes 3 days. "Train travel" is more of a general concept and that's why it doesn't really work in the context of describing a particular instance of it.
Once I said, "I was late for the train" and I was corrected by someone who explained that I should have said, "I missed the train". There was no context, just an English execise. I wonder if it's a mistake to say "to be late for+means of transport"? If it is correct, is there any difference...
2019年3月10日 · But in AE, only answer B is correct. "By train" is a way to travel (by car, by foot, by airplane, etc.). You can say "we travelled by train" (a method) but then you cannot say "which arrived at 6:45", because the method does not arrive at a specific time. "By train" has an identical meaning to "by railway" or "by railroad".
2016年8月20日 · Aug 20, 2016. #5. To board a conveyance (a train; a bus; an airplane; a ferry boat) merely means to enter that conveyance, or to get on. It has nothing to do with actually travelling on it: We all boarded the bus, but then its engine died, and we had to get off and take another one. In your case, whether you are travelling a long distance or a ...
