Python 没有名为'；rpytools'；？

我正在尝试使用R中的网状库。我使用了“functions.py”示例来测试它：

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

在R studio（3.5.2版）中，我有：

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

但是，这将返回一个错误：

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

所以我被困在这里了。如果有帮助的话，我还将分享我的Python是64位的，版本是3.6.5。有人知道怎么做吗

谢谢

rpytools

是由

networkite

提供的模块，应该放在模块路径上。例如，我看到：

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

注意最后一个条目，它提供了导入时可以在其中找到

rpytools

的路径。你看到类似的东西了吗？

安装网状软件包，创建conda env，安装keras、tf和任何你需要的东西

找到当前R版本的包的存储位置，并找到网状文件夹，其中应该有一个python/rpytools目录。 （在我的例子中，R包安装在“C:\Users\abc\Documents\R\win library\4.1\Networkite\python”中）

使用此代码：

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