在 python 块中调用 R object 时出错（R 降价）

Question

enter image description here I am using the library reticulate to run some python code in RStudio. The syntax to call an R object in a python chunk is: r.object. Unfortunatly I have this error message when calling my r.object in the python code portion... (screenshot below). Also I am running my code on an rstudio instance on an amazon cloud (should not pose a problem...) Do not really understand why...

Thanks in advance for helping:)

You will also find the R code portion that comes right before i run the python chunk enter image description here

It's hard to know what your trying to do, but I can help you read the error.

You can see that the error is coming from line 10 which is this one:

for f in r.test_idx.keys():

You don't have any object before this line that instantiates r. As far as the code is concerned, r does not exist and you are trying to call the test_idx.keys() method from the r object.

There's actually nothing in the for loop that references anything outside of it.

Are these values defined in the R chunks of the code?

If so, can you post the R chunks that precede this and I can help further.

Kind Regards
