error message

[fangj3]

Hi, when I run the tutorial, it gives me:

performance <- run_perturbBench(act = act_scores, meta = meta, method_id = "zscore_ppsp")
Error in py_get_attr(x, name, FALSE) :
AttributeError: module 'decoupler' has no attribute 'get_performances'
Run reticulate::py_last_error() for details.

I run reticulate::py_last_error(), it gives me:

── Python Exception Message ──────────────────────────────────────────────────────────────────────────
AttributeError: module 'decoupler' has no attribute 'get_performances'

── R Traceback ───────────────────────────────────────────────────────────────────────────────────────

1. └─benchmarKIN::run_perturbBench(...)

3. └─reticulate:::$.python.builtin.module(dc, "get_performances")

4. └─reticulate::py_get_attr(x, name, FALSE)
   

What's the problem?
Thanks a lot!
