一.union与union all 首先建两个view create or replace view test_view_1 as as c from dual union as c from dual union as c from dual ; ----- create or replace view test_view_2 as as c from dual union as c from dual union as c from dual order by a desc, b desc,…
函数:tf.nn.sparse_softmax_cross_entropy_with_logits(_sentinel=None,labels=None,logits=None,name=None) #如果遇到这个问题:Rank mismatch: Rank of labels (received 2) should equal rank of logits minus 1 (received 2). 一般是维度没有计算好: 函数是将softmax和cross_entropy放在一起计算,对于分…
