没有名为"rpytools"的模块? [英] No module named 'rpytools'?

问题描述

我正在尝试使用R中的网状库.我使用"functions.py"示例对其进行了测试:

I'm trying to work with the reticulate library in R. I used the "functions.py" example to test it out:

# functions.py file
def add(x, y): 
    return x + y

在R Studio(版本3.5.2)中，这就是我所拥有的:

In R studio (Version 3.5.2), this is what I have:

library(reticulate)  
source_python('functions.py')

但是，这将返回错误:

Error in py_set_attr_impl(x, name, value) : 
  Evaluation error: ModuleNotFoundError: No module named 'rpytools'.

所以我被困在这里.如果有帮助，我还将分享我的Python是64位版本3.6.5.有人知道该怎么做吗?

So I'm stuck here. If it helps, I'll also share that my Python is 64-bit and version 3.6.5. Anyone know how to go about this?

谢谢

推荐答案

rpytools 是 reticulate 提供的模块，应放在您的模块路径上.例如，我看到:

rpytools is a module provided by reticulate and should be placed on the module path for you. For example, I see:

> library(reticulate)
> sys <- import("sys", convert = TRUE)
> sys$path

请注意最后一个条目，该条目提供导入时在其中找到 rpytools 的路径.你看到类似的东西吗?

Note the last entry, which provides the path where rpytools would be found on import. Do you see something similar?
