我正在尝试使用 python 3.6.13 作为约束来设置遗留项目。虽然我在尝试安装 pandas 版本 0.18.1 时遇到问题

日志如下：

当我尝试使用以下命令启动dfs时:

start-dfs.sh

我收到一个错误说:

我在Linux Mint 16上使用R版本(3.0.1)当我尝试使用下载tm包时

install.packages("tm")

它给我一个错误说:

package ‘tm’ is not available (for R version 3.0.1)

我怎么可能解决这个问题？

我正在使用OpenCV canny边缘检测模块来查找图像的轮廓，从而获得黑白输出图像。

这是该代码：

  gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
  blurred = cv2.GaussianBlur(gray, (3, 3), 0)
  edged = cv2.Canny(blurred, 180, 200)

现在，我想将此图像以SVG文件格式写入磁盘。如何从广告图片中获取相同内容？
