python-Error Message: 'float' object cannot be interpreted as an integer

网上有一中出现的情况如下：

batch = 200for x in range(len(order_nos) / batch + 1): # do something

此代码在python2下运行正常但是在python3下面运行会出现问题;

原因在于两个版本下对float的处理方法不同，python2下在运行/的时候产生的结果会自动忽略小数，直接取整数，而python3中是会保留小数点的所以产生了错误

其次，对于

y_linear=x+(5.)*np.random.randn(14.)

这个代码片也会报这个错误原因是在python3中randn里的14.的小数点无法被自动忽略转换成整型导致了错误，所以要根据情况更换使用方法。randn（）中的参数一定是正整数
