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:
# 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:
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?
谢谢

安装 reticulate 包,创建 conda env 并安装 keras、tf 和任何你需要的东西。
找到您当前 R 版本的包的存储位置,并找到 reticulate 文件夹,里面应该有一个 python/rpytools 目录。 (在我的例子中,R 包安装在 'C:\Users\abc\Documents\R\win-library\4.1\reticulate\python')
使用此代码:
library(reticulate)
sys <- import("sys", convert = TRUE)
sys$path
最后一个条目显示了您应该复制 rpytools 文件夹的目录。在此之后,事情开始对我有用。

rpytools
是reticulate
提供的模块,应放在您的模块路径上。例如,我看到:
> library(reticulate)
> sys <- import("sys", convert = TRUE)
> sys$path

请注意最后一个条目,该条目提供了在导入时可以找到rpytools
的路径。你看到类似的东西吗?
