project配置工作目录

project配置工作目录

本文介绍了在Eclipse 3.8.1中使用PyDev-project配置工作目录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

  IOError:我在Eclipse 3.8.1中运行一个python脚本, [Errno 2]没有这样的文件或目录

问题出现在代码行:

  train_labels = np.loadtxt(./ examples / data / class_train.labels)
/ pre>

这是我的项目的屏幕截图:





看起来相对路径从脚本本身的位置开始,我想要相对路径从项目的根目录开始,即RLScore-文件夹,如图所示。



如何配置?



我不想编辑代码,因为这不是我自己的代码,我需要做的编辑到许多其他文件的分布。

解决方案

尝试:

  train_labels = np.loadtxt(../ data / class_train.labels)


I'm trying run a python script in Eclipse 3.8.1 but I keep getting the error message:

IOError: [Errno 2] No such file or directory

The problem occurs in a code line:

train_labels = np.loadtxt("./examples/data/class_train.labels")

Here is a screenshot of my project:

It seems the relative path starts from the location of the script itself, whereas I would want the relative path start from the root directory of the project, that is the RLScore-folder as you can see in the image.

How do I configure this?

P.S. I wouldn't want to edit the code, because this is not my own code and I would need to do the editing into many other files in the distribution.

解决方案

try :

train_labels = np.loadtxt("../data/class_train.labels")
