我正在尝试使用pip安装pandas来运行一些基于pandas的Python程序.我已经安装了pip.我尝试使用谷歌搜索和SO'ing但没有找到解决此错误的方法.有人可以分享你的意见吗？
C:\> pip install pandas
错误:
pip is not recognized as an internal or external command, operable program or batch file.
我想用逗号分隔符替换每个字段之间的空白区域.有人让我知道我该怎么做.我尝试了下面的命令,但它不起作用.谢谢.

我正在从一个文件中读取数字.当我尝试将每个数字放入一个双维数组时,它给出了我的错误.我如何摆脱这个消息？我的变量:FILE*fp; char line [80];
错误:从char*转换为int会失去精度
码:-
#include<stdio.h>
#include<string.h>
int main()
{
FILE *fp;
char line[80],*pch;
int points[1000][10];
int centroid[1000][10];
float distance[1000][10];
int noofpts=0,noofvar=0,noofcentroids=0;
int i=0,j=0,k;
fp=fopen("kmeans.dat","r");
while(fgets(line,80,fp)!=NULL)
{
j=0;
pch=strtok(line,",");
while(pch!=NULL)
{
points[i][j]=(int)pch;
pch=strtok(NULL,",");
noofvar++;
j++;
}
noofpts++;
i++;
}
noofvar=noofvar/noofpts;
printf("No of points-%d\n",noofpts);
printf("No of variables-%d\n",noofvar);
return 0;
}
我试图截断GBQ中的现有表,但是当我运行它时,以下命令失败.是否有任何特定的命令或语法来做到这一点.我查看了GBQ文档,但没有运气.
TRUNCATE TABLE [dw_test.test];
我是R的新手,我正在尝试将.Rdata格式文件转换为逗号分隔的文本文件格式.有人可以帮我解决这个问题吗？
我想知道为什么我在下面的代码中出现分段错误.
int main(void)
{
char str[100]="My name is Vutukuri";
char *str_old,*str_new;
str_old=str;
strcpy(str_new,str_old);
puts(str_new);
return 0;
}
我正在尝试YYYY-MM-DD HH:MM:SS从Netezza向Oracle 插入带格式的记录,但是我的日期类型无效.
