出错是因为if语句下面的代码没有缩进。需要将下面的代码缩进一下。同时，还需要将第二个for循环的缩进也加上。修改后的代码如下： def FNormalizeMultUseData(data,normalize): data = np.array(data) listlow = normalize[-1, 0] listhigh = normalize[-1, 1] delta = listhigh - listlow if delta != 0: for j in range(0,data.shape[0]): data[j,-1] = (data[j,-1] - listlow)/delta data[j,-1] = data[j,-1]*(normalize[-1,1]-normalize[-1,0])+normalize[-1,0] for i in range(0, data.shape[1]-1): listlow = normalize[i, 0] listhigh = normalize[i, 1] delta = listhigh - listlow if delta != 0: for j in range(0,data.shape[0]): data[j,i] = (data[j,i] - listlow)/delta return data

怎么在集群安装安装hbase

您好，关于如何在集群上安装HBase，步骤大致如下： 1. 在HBase官网上下载最新版本的HBase，并解压到需要安装的目录下； 2. 配置HBase的环境变量：将HBase目录的bin子目录加入到PATH环境变量中； 3. 修改HBase配置文件：在HBase目录下的conf子目录中找到hbase-site.xml文件，并进行相应的配置，如指定HBase的Zookeeper节点等； 4. 启动HBase：使用HBase的bin目录下的start-hbase.sh脚本启动HBase； 5. 验证HBase是否正常运行：使用HBase自带的shell命令行工具操作HBase。 注意：以上步
