1 训练时 model = Word2Vec(x, size=250, window=5, min_count=5, workers=12, iter=10, sg=1) 这句代码一直报错 查了发现 size和iter依然是时代的眼泪了.改成下面 model = Word2Vec(x, vector_size=250, window=5, min_count=5, workers=12, epochs=10, sg=1) 2:遍历这个 模型时 使用的代码 for i, word in en

问题:xcode 7编译错误:bitcode is not supported on versions of iOS prior to 6.0 解决:Build Options | Enable Bitcode 设置为No即可 原因:这是Apple Watch使用的 问题:Build iOS时提示没法拉起Xcode: UnityException: Launching iOS project via Xcode4 failed. Check editor log for details. 解决:

一.作用域 对于变量的作用域,执行声明并在内存中存在,该变量就可以在下面的代码中使用. if 1==1: name = 'wupeiqi' print name 二.三元运算 result = 值1 if 条件 else 值2 如#果条件成立,值1付给result否则值2付给result 如果条件为真:result = 值1如果条件为假:result = 值2 name = 'sb' if 1==1 else '2b' input = raw_input() result = '2b'
