Error trying to use with R encountered during "py_install("fasterrisk", pip=TRUE, envname="FasterRisk-environment")"

[schwa021]

Hi there,

I'm trying to get this running in R. I don't know anything about Python. I was trying to follow your R instructions.

** I installed Python (had to do this from Python web site - reticulate didn't work, installed latest version 3.12.0)**

Executed the following - and both worked (with version = "3.12.0")

virtualenv_create(envname="FasterRisk-environment", version = version)
use_virtualenv("FasterRisk-environment")

Then tried to install FasterRisk per instructions

py_install("fasterrisk", pip=TRUE, envname="FasterRisk-environment")

...and encountered the error reported below. Like I said - I have don't know anything about Python, so perhaps this is something simple/obvious.

Using virtual environment "FasterRisk-environment" ...

Error: Error installing package(s): "fasterrisk"

OK - I downgraded to 3.9.12, and managed to get that part to work - sorry for the clutter.

However, a few steps later in your instructions I encountered the following while trying to download the sample data:

Error in py_get_attr_impl(x, name, silent) :
AttributeError: module 'fasterrisk' has no attribute 'utils'
Run reticulate::py_last_error() for details.

I ran reticulate::py_last_error() and got the following:

── Python Exception Message ────────────────────────────────────────────────────────────────────────────────────────
AttributeError: module 'fasterrisk' has no attribute 'utils'

── R Traceback ─────────────────────────────────────────────────────────────────────────────────────────────────────
▆

1. ├─fasterrisk$utils
2. └─reticulate:::$.python.builtin.module(fasterrisk, utils)
3. └─reticulate:::$.python.builtin.object(x, name)

4. └─reticulate:::py_get_attr_or_item(x, name, TRUE)
   

5.   └─reticulate::py_get_attr(x, name)
   

6.     └─reticulate:::py_get_attr_impl(x, name, silent)
   

So, it seems (knowing nothing about Python) that "fasterrisk" is missing an attribute named "utils"
