py_call_impl中的网状错误（可调用、dots$args、dots$keywords）

Question

我有一个错误，我无法用网状结构解决

library(reticulate)

env = "ChildRecordsR"
use_condaenv(condaenv = env, required = T)

pygamma <- import("pygamma_agreement")
pyanote <- import("pyannote.core")


Continuum <- pygamma$Continuum
Segment <- pyanote$Segment

seg = pyanote$Segment(1,10)
Continuum$add("test1",Segment(1,10),"T1")

Continuum$add返回以下错误

 Error in py_call_impl(callable, dots$args, dots$keywords) : 
  AttributeError: 'str' object has no attribute 'duration' 

然而，我可以清楚地找到持续时间

> seg$duration
9.0

有人知道吗
